Aircraft hijacking

Last updated

Aircraft hijacking (also known as skyjacking, plane jacking, air robbery, air piracy, or aircraft piracy, with the latter term being used within the special aircraft jurisdiction of the United States) is the unlawful seizure of an aircraft by an individual or a group. [1] Dating from the earliest of hijackings, most cases involve the pilot being forced to fly according to the hijackers demands. However, in rare cases, the hijackers have flown the aircraft themselves and used them in suicide attacks; most notably in the September 11 attacks, and in several cases, planes have been seized by the official pilot or co-pilot. [2] [3] [4]

Jurisdiction is the practical authority granted to a legal body to administer justice within a defined field of responsibility, e.g., Michigan tax law. In federations like the United States, areas of jurisdiction apply to local, state, and federal levels; e.g. the court has jurisdiction to apply federal law.

United States Federal republic in North America

The United States of America (USA), commonly known as the United States or America, is a country comprising 50 states, a federal district, five major self-governing territories, and various possessions. At 3.8 million sq mi (9.8 million km2), the United States is the world's third or fourth largest country by total area and is slightly smaller than the entire continent of Europe's 3.93 million sq mi (10.2 million km2). With a population of more than 327 million people, the U.S. is the third most populous country. Most of the country is located contiguously in North America between Canada and Mexico.

Crime unlawful act forbidden and punishable by criminal law

In ordinary language, a crime is an unlawful act punishable by a state or other authority. The term "crime" does not, in modern criminal law, have any simple and universally accepted definition, though statutory definitions have been provided for certain purposes. The most popular view is that crime is a category created by law; in other words, something is a crime if declared as such by the relevant and applicable law. One proposed definition is that a crime or offence is an act harmful not only to some individual but also to a community, society or the state. Such acts are forbidden and punishable by law.


Unlike carjacking or sea piracy, an aircraft hijacking is not usually committed for robbery or theft. Individuals driven by personal gain often divert planes to destinations where they are not planned to go. [5] Some hijacking situations intend to use passengers or crew as hostages, either for monetary ransom or for some political or administrative concession by authorities. Various motives have driven such occurrences, such as demanding the release of certain high-profile individuals or for the right of political asylum (notably Flight ET 961). Hijackings involving hostages have produced violent confrontations between hijackers and the authorities, during negotiation and settlement. In the case of Lufthansa Flight 181 and Air France Flight 139, the hijackers were not satisfied and showed no inclination to surrender, resulting in attempts by special forces to rescue passengers. [6]

Carjacking is a robbery in which the item taken over is a motor vehicle.

Piracy Act of robbery or criminal violence at sea

Piracy is an act of robbery or criminal violence by ship or boat-borne attackers upon another ship or a coastal area, typically with the goal of stealing cargo and other valuable items or properties. Those who engage in acts of piracy are called pirates. The earliest documented instances of piracy were in the 14th century BC, when the Sea Peoples, a group of ocean raiders, attacked the ships of the Aegean and Mediterranean civilizations. Narrow channels which funnel shipping into predictable routes have long created opportunities for piracy, as well as for privateering and commerce raiding. Historic examples include the waters of Gibraltar, the Strait of Malacca, Madagascar, the Gulf of Aden, and the English Channel, whose geographic structures facilitated pirate attacks. A land-based parallel is the ambushing of travelers by bandits and brigands in highways and mountain passes. Privateering uses similar methods to piracy, but the captain acts under orders of the state authorizing the capture of merchant ships belonging to an enemy nation, making it a legitimate form of war-like activity by non-state actors.

Hostage person or entity which is held by one of two belligerent parties to the other or seized as security for the carrying out of an agreement, or as a preventive measure against certain acts of war

A hostage is a person seized by a criminal abductor in order to compel another party such as a relative, employer, law enforcement or government to act, or refrain from acting, in a certain way, often under threat of serious physical harm to the hostage(s) after expiration of an ultimatum. The 1911 edition of the Encyclopædia Britannica defines a hostage as "a person who is handed over by one of two belligerent parties to the other or seized as security for the carrying out of an agreement, or as a preventive measure against certain acts of war."

In most jurisdictions of the world, hijacking a plane is punishable by life imprisonment or a long prison sentence. In most jurisdictions where the death penalty is a legal punishment, aircraft hijacking is a capital crime, including in China, India, and the U.S. states of Georgia and Mississippi.

Georgia (U.S. state) State of the United States of America

Georgia is a state located in the southeastern region of the United States. Georgia is the 24th largest and 8th-most populous of the 50 United States. Georgia is bordered to the north by Tennessee and North Carolina, to the northeast by South Carolina, to the southeast by the Atlantic Ocean, to the south by Florida, and to the west by Alabama. The state's nicknames include the Peach State and the Empire State of the South. Atlanta, a "beta(+)" global city, is both the state's capital and largest city. The Atlanta metropolitan area, with an estimated population of 5,949,951 in 2018, is the 9th most populous metropolitan area in the United States and contains about 60% of the entire state population.

Mississippi State of the United States of America

Mississippi is a state located in the southeastern region of the United States. Mississippi is the 32nd largest and 34th-most populous of the 50 United States. Mississippi is bordered to the north by Tennessee, to the east by Alabama, to the south by the Gulf of Mexico, to the southwest by Louisiana, and to the northwest by Arkansas. Mississippi's western boundary is largely defined by the Mississippi River. Jackson is both the state's capital and largest city. Greater Jackson, with an estimated population of 580,166 in 2018, is the most populous metropolitan area in Mississippi and the 95th-most populous in the United States.


Airplane hijackings have occurred since the early days of flight. These can be classified in the following eras: 1929–1957, 1958–1979, 1980–2000 and 2001–present. Early incidents involved light planes but this later involved passenger aircraft as commercial aviation became widespread.

Commercial aviation transport system providing air transport for hire

Commercial aviation is the part of civil aviation that involves operating aircraft for hire to transport passengers or multiple loads of cargo.


Between 1929 and 1957, there were fewer than 20 incidents of reported hijackings worldwide and several occurred in Eastern Europe. [7] One of the first unconfirmed hijackings occurred in December 1929. J. Howard "Doc" DeCelles was flying a postal route for a Mexican firm Transportes Aeras Transcontinentales, ferrying mail from San Luis Potosí to Torreon and then on to Guadalajara. A lieutenant named Saturnino Cedillo, the governor of the state of San Luis Potosí, ordered him to divert. Several other men were also involved, and through an interpreter, DeCelles had no choice but to comply. He was allegedly held captive for several hours under armed guard before being released. [8]

Eastern Europe Eastern part of the European continent

Eastern Europe is the eastern part of the European continent. There is no consistent definition of the precise area it covers, partly because the term has a wide range of geopolitical, geographical, cultural, and socioeconomic connotations. There are "almost as many definitions of Eastern Europe as there are scholars of the region". A related United Nations paper adds that "every assessment of spatial identities is essentially a social and cultural construct". One definition describes Eastern Europe as a cultural entity: the region lying in Europe with the main characteristics consisting of Greek, Byzantine, Eastern Orthodox, Russian, and some Ottoman culture influences. Another definition was created during the Cold War and used more or less synonymously with the term Eastern Bloc. A similar definition names the formerly communist European states outside the Soviet Union as Eastern Europe. The majority of historians and social scientists view such definitions as outdated or relegated, but they are still sometimes used for statistical purposes.

San Luis Potosí State of Mexico

San Luis Potosí, officially the Free and Sovereign State of San Luis Potosí, is one of the 31 states which, with the Federal District, comprise the 32 Federal Entities of Mexico. It is divided in 58 municipalities and its capital city is San Luis Potosí City.

Torreón Municipal seat in Coahuila, Mexico

Torreón is a city and seat of Torreón Municipality in the Mexican state of Coahuila. As of 2015, the city's population was 679,288. The metropolitan population as of 2015 was 1,497,734, making it the ninth-biggest metropolitan area in the country and the largest metropolitan area in state of Coahuila, as well as one of Mexico's most important economic and industrial centers. The cities of Torreón, Gómez Palacio, Lerdo, Matamoros, Francisco I. Madero, San Pedro, Bermejillo, and Tlahualilo form the area of La Laguna or the Comarca Lagunera, a basin within the Chihuahuan Desert.

The first recorded aircraft hijack took place on February 21 1931, in Arequipa, Peru. Byron Richards, flying a Ford Tri-Motor, was approached on the ground by armed revolutionaries. He refused to fly them anywhere during a 10-day standoff. Richards was informed that the revolution was successful and he could be freed in return for flying one of the men to Lima. [9] The following year, in September 1932, a Sikorsky S-38 with registration P-BDAD, still bearing the titles of Nyrba do Brasil was seized in the company's hangar by three men, who took a fourth as a hostage. Despite having no flying experience, they managed to take-off. However, the aircraft crashed in São João de Meriti, killing the four men. Apparently, the hijack was related to the events of the Constitutionalist Revolution in São Paulo and it is considered to be the first hijack that took place in Brazil.

Arequipa Region capital in Peru

Arequipa is a city located in the province and the eponymous department of Peru. It is the seat of the Constitutional Court of Peru and often dubbed "legal capital of Peru." It is the second most populated city in Peru, after Lima, with an urban population of 1,008,290 inhabitants according to the 2017 national census.

Peru Republic in South America

Peru, officially the Republic of Peru, is a country in western South America. It is bordered in the north by Ecuador and Colombia, in the east by Brazil, in the southeast by Bolivia, in the south by Chile, and in the west by the Pacific Ocean. Peru is a megadiverse country with habitats ranging from the arid plains of the Pacific coastal region in the west to the peaks of the Andes mountains vertically extending from the north to the southeast of the country to the tropical Amazon Basin rainforest in the east with the Amazon river.

Lima Capital city in Peru

Lima is the capital and the largest city of Peru. It is located in the valleys of the Chillón, Rímac and Lurín rivers, in the central coastal part of the country, overlooking the Pacific Ocean. Together with the seaport of Callao, it forms a contiguous urban area known as the Lima Metropolitan Area. With a population of more than 9 million, Lima is the most populous metropolitan area of Peru and the third-largest city in the Americas, behind São Paulo and Mexico City.

On October 28 1939, the first murder on a plane took place in Brookfield, Missouri. The victim was Carl Bivens, a flight instructor, who was teaching a man named Earnest P. "Larry" Pletch. While airborne in a Taylor Club monoplane, Pletch shot Bivens twice in the back of the head. Pletch later told prosecutors, "Carl was telling me I had a natural ability and I should follow that line", adding, "I had a revolver in my pocket and without saying a word to him, I took it out of my overalls and I fired a bullet into the back of his head. He never knew what struck him." The Chicago Daily Tribune stated it was one of the most spectacular crimes of the 20th century. Pletch pleaded guilty and was sentenced to life in prison. However, he was released on March 1 1957 after serving 17 years, and lived until June 2001. [8] [10] [11]

In 1942, two New Zealanders, a South African and an Englishman achieved the first confirmed in-air hijack when they violently captured an Italian seaplane that was flying them to a prison camp. As they approached an Allied base, they were strafed by Spitfires and forced to land on the water. However, all on board survived to be picked up by a British boat. [12]

In the years following World War II, Philip Baum, an aviation security expert suggests that the development of a rebellious youth "piggybacking on to any cause which challenged the status quo or acted in support of those deemed oppressed", may have been a contributor to attacks against the aviation industry. [8] The first hijacking of a commercial flight occurred on the Cathay Pacific Miss Macao on July 16 1948. [13] After this incident and others in the 1950s, airlines recommended that flight crews comply with the hijackers demands than risk a violent confrontation. [8] There were also various hijacking incidents and assaults on planes in China and the Middle East. [8]

The first hijacking of a flight for political reasons happened in Bolvia, affecting the airline Lloyd Aereo Boliviano on September 26 1956. The DC-4 was carrying 47 prisoners who were being transported from Santa Cruz, Bolivia to El Alto, in La Paz. A political group was waiting to take them to a concentration camp located in Carahuara de Carangas, Oruro. The 47 prisoners overpowered the crew and gained control of the aircraft while airborne and diverted the plane to Tartagal, Argentina. Prisoners took control of the aircraft and received instructions to again fly to Salta, Argentina as the airfield in Tartagal was not big enough. Upon landing, they told the government of the injustice they were subjected to, and received political asylum.


Between 1958 to 1967, there were approximately 40 hijackings worldwide. [7] Beginning 1958, hijackings from Cuba to other destinations started to occur, and then in 1961, hijackings to Cuba became prevalent. [7] The first happened on May 1 1961 on a flight from Miami to Key West. The perpetrator, armed with a knife and gun, forced the captain to land in Cuba. [8] [14] Elsewhere, Australia was relatively untouched by the threat of hijackings until July 19 1960. On that evening, a 22-year-old Russian man attempted to divert Trans Australia Airlines Flight 408 to Darwin or Singapore. [8] The crew were able to subdue the man after a brief struggle.

In the 1960s, there were over 200 attempts of hijackings involving U.S aircraft—77 successful and 23 unsuccessful. [14] Recognizing the danger early, the FAA issued a directive on July 28 1961, which prohibits unauthorized persons from carrying concealed firearms and interfering with crew member duties. [14] The Federal Aviation Act of 1958 was amended to impose severe penalties for those seizing control of a commercial aircraft. [14] Airlines could also refuse to transport passengers who were likely to cause danger. That same year, the FAA and Department of Justice created the Peace Officers Program which put trained marshals on flights. [14] A few years later, on May 7 1964, the FAA adopted a rule requiring that cockpit doors on commercial aircraft be kept locked at all times. [14]

Extortion attempts

In a five-year period (1968–1972) the world experienced 326 hijack attempts, or one every 5.6 days. [15] The incidents were frequent and often just an inconvenience, which resulted in television shows creating parodies. [16] Time magazine even ran a lighthearted comedy piece called "What To Do If The Hijacker Comes". [17] Most incidents occurred in the United States: there were two distinct types: hijackings for transportation elsewhere and hijackings for extortion with the threat of harm. [15] Between 1968 and 1972, there were 90 recorded transport attempts to Cuba. In contrast, there were 26 extortion attempts (see table on the right). Incidents also became problematic outside of the U.S. For instance, in 1968, El Al Flight 426 was seized by the Popular Front for the Liberation of Palestine (PFLP) militants on 23 July which lasted 40 days making it one of the longest. This record was later beaten in 1999. [18] As a result of the evolving threat, President Nixon issued a directive in 1970 to promote security at airports, electronic surveillance and multilateral agreements for tackling the problem. [14]

Furthermore, a report by the International Civil Aviation Organization (ICAO) in July 1970 revealed the need for action. Beginning of 1969 until the end of June 1970, there were 118 incidents of unlawful seizure of aircraft and 14 incidents of sabotage and armed attacks against civil aviation. This involved airlines of 47 countries and more than 7,000 passengers. In this period, 96 people were killed and 57 were injured as a result of hijacking, sabotage and armed attacks. The ICAO stated that this is not isolated to one nation or one region, but a worldwide issue to the safe growth of international civil aviation. [19] Incidents also became notorious—in 1971, a man known as D. B. Cooper hijacked a plane and extorted US$200,000 in ransom before parachuting over Oregon. He was never identified. [20] On August 20 1971, a Pakistan Air Force T-33 military plane was hijacked prior the Indo-Pakistani war of 1971 in Karachi. Lieutenant Matiur Rahman attacked Officer Rashid Minhas and attempted to land in India. Minhas deliberately crashed the plane into the ground near Thatta to prevent the diversion. [21]

Countries around the world continued their efforts to tackle crimes committed on-board planes. The Tokyo Convention, drafted in 1958, established an agreement between signatories that the "state in which the aircraft is registered is competent to exercise jurisdiction over crimes committed on board that aircraft while it is in flight". [14] While the Convention does not make hijacking an international crime, it does contain provisions which obligate the country in which a hijacked aircraft lands to restore the aircraft to its responsible owner, and allow the passengers and crew to continue their journey. [14] [22] The Convention came into force in December 1969. A year later, in December 1970, the Hague Convention was drafted which punishes hijackers, enabling each state to prosecute a hijacker if that state does not extradite them, and to deprive them from asylum from prosecution. [14]

On December 5 1972, the FAA issued emergency rules requiring all passengers and their carry-on baggage to be screened. [23] Airports slowly implemented walk-through metal detectors, hand-searches and x-ray machines, to prohibit weapons and explosive devices. [23] These rules came into effect on January 5 1973 and were welcomed by most of the public. [5] Between 1968 to 1977, there were approximately 41 hijackings per year. [7]


By 1980, airport screening and greater cooperation from the international community led to fewer successful hijackings; the number of events had significantly dropped below the 1968 level. [24] Between 1978 and 1988, there were roughly 26 incidents of hijackings a year. [7] A new threat emerged in the 1980s and this was from organised terrorists destroying aircraft to draw attention. For instance, terrorist groups were responsible for the bombing of Air India Flight 182 over the Irish coast. In 1988, Pan Am Flight 103 was bombed flying over Scotland. [7] Terrorist activity which included hijack attempts in the Middle East were also a cause of concern. [25]

During the 1990s, there was relative peace in the United States airspace as the threat of domestic hijacking was seen as a distant memory. [26] Globally, however, hijackings still persisted. Between 1993 and 2003, the highest number of hijackings occurred in 1993 (see table below). This number can be attributed to events in China where hijackers were trying to gain political asylum in Taiwan. [26] Europe and the rest of East Asia were not immune either. On December 26 1994, Air France Flight 8969 with 172 passengers and crew was hijacked after leaving Algiers. Authorities believed that the goal was to crash the plane into the Eiffel Tower. On June 21 1995, All Nippon Airways Flight 857 was hijacked by a man claiming to be a member of the Aum Shinrikyo religious cult, demanding the release of its imprisoned leader Shoko Asahara. The incident was resolved when the police stormed the plane.

On October 17 1996, the first hijacking that was brought to an end while airborne was carried out by four operatives of the Austrian special law enforcement unit Cobra on a Russian Aeroflot flight from Malta to Lagos, Nigeria, aboard a Tupolev Tu-154. The operatives escorted inmates detained for deportation to their homelands and were equipped with weapons and gloves. [27] [28] On 12 April 1999, six ELN members hijacked a Fokker 50 of Avianca Colombian Airlines Flight 9463, flying from Bogotá to Bucaramanga. Many hostages were held for more than a year, and the last hostage was finally freed 19 months after the hijacking. [29] [30]

Annual Hijack Incidents, 1993–2003 [26]


On September 11 2001, four airliners were hijacked by 19 Al-Qaeda Islamic extremists: American Airlines Flight 11, United Airlines Flight 175, American Airlines Flight 77 and United Airlines Flight 93. The first two planes were deliberately crashed into the Twin Towers of the World Trade Center and the third was crashed into The Pentagon building. The fourth, crashed in a field in Stonycreek Township near Shanksville, Pennsylvania after crew and passengers attempted to overpower the hijackers. Authorities believed that the intended target was the U.S. Capitol. In total, 2,996 people perished and more than 6,000 were injured in the attacks, making the hijackings the most deadly in modern history.

Following the attacks, the U.S formed the Transportation Security Administration (TSA) to handle airport screening at U.S airports. Government agencies around the world tightened their airport security, procedures and intelligence gathering. [31] Until the September 11 attacks, there had never been incident whereby aircraft were used as a weapon of mass destruction. The 9/11 Commission report stated that it was always assumed that a "hijacking would take the traditional form", [32] therefore, airline crews never had a contingency plan for a suicide-hijacking. [33] As Patrick Smith, an airline pilot, summarizes:

"One of the big ironies here is the success of the 2001 attacks had nothing to do with airport security in the first place. It was a failure of national security. What the men actually exploited was a weakness in our mind-set – a set of presumptions based on decades-long track record of hijackings. In years past, a hijacking meant a diversion, with hostage negotiations and standoffs. The only weapon that mattered was the intangible one: the element of surprise." [34]

Throughout the mid-2000s, hijackings still occurred but there were much fewer incidents and casualties. The number of incidents had been declining, even before the September 11 attacks. One notable incident in 2006 was the hijacking of Turkish Airlines Flight 1476, flying from Tirana to Istanbul, which was seized by a man named Hakan Ekinci. The aircraft, with 107 passengers and 6 crew, made distress calls to air traffic control and the plane was escorted by military aircraft before landing safely at Brindisi, Italy. In 2007, several incidents occurred in the Middle East and Northern Africa, one of which men claimed to be affiliated with Al-Qaeda. [35] Towards the end of the decade, AeroMexico experienced its first terror incident when Flight 576 was hijacked by a man demanding to speak with President Calderón.

Since 2010, the Aviation Safety Network estimates there have been 15 hijackings worldwide with 3 fatalities. [36] This is a considerable lower figure than in previous decades which can be attributed to greater security enhancements and awareness of September 11–style attacks. [37] [38] On June 29 2012, an attempt was made to hijack Tianjin Airlines Flight GS7554 from Hotan to Ürümqi in China. More recently was the 2016 hijacking of EgyptAir Flight MS181, involving an Egyptian man who claimed to have a bomb and ordered the plane to land in Cyprus. He surrendered several hours later, after freeing the passengers and crew. [37]


As a result of the U.S–Cuba hijacking epidemic of the late 1960s to early 1970s, international airports introduced screening technology such as metal detectors, x-ray machines and explosive detection tools. In the U.S, these rules were enforced starting from January 1973 [5] and were eventually copied around the world. These security measures did make hijacking a "higher-risk proposition" and deter criminals in later decades. [39] Until September 2001, the FAA set and enforced a "layered" system of defense: hijacking intelligence, passenger pre-screening, checkpoint screening and on-board security. The idea was that if one layer were layer to fail, another would be able stop a hijacker from boarding a plane. However, the 9/11 Commission found that this layered approach was flawed and unsuitable to prevent the September 11 attacks. [40] The U.S Transportation Security Administration has since strengthened this approach, with a greater emphasis on intelligence sharing. [41] [42]

On-board security

In the history of hijackings, most incidents involved planes being forced to land at a certain destination with demands. As a result, commercial airliners adopted a "total compliance" rule which taught pilots and cabin crew to comply with the hijackers demands. [34] Crews advise passengers to sit quietly to increase their chances of survival. The ultimate goal is to land the plane safely and let the security forces handle the situation. The FAA suggested that the longer a hijacking persisted, the more likely it would end peacefully with the hijackers reaching their goal. [43] Although total compliance is still relevant, the events of September 11 changed this paradigm as this technique cannot prevent a suicide hijacking.

It is now evident that each hijacking situation needs to be evaluated on a case-by-case basis. Cabin crew, now aware of the severe consequences, have a greater responsibility for maintaining control of their aircraft. Most airlines also give crew members training in self-defense tactics. [44] Ever since the 1970s, crew are taught to be vigilant for suspicious behaviour. For example, passengers who have no carry-on luggage, or are standing next to the cockpit door with fidgety movements. There have been various incidents when crew and passengers intervened to prevent attacks: on December 22 2001, Richard Reid attempted to ignite explosives on American Airlines Flight 63. In 2009, on Northwest Flight 253, Umar Farouk Abdulmutallab attempted to detonate explosives sewn into his underwear. In 2012, the attempted hijacking of Tianjin Airlines Flight 7554 was stopped when cabin crew placed a trolley in-front of the cockpit door and asked passengers for help. [45]

American Airlines Flight 11

In the September 11 attacks, crew on one of the hijacked planes went beyond their scope of training by informing the airline ground crew about the events on-board. In separate phone calls, Amy Sweeney and Betty Ong provided information on seat numbers of the attackers and passenger injuries. This helped authorities identify them.

Cockpit security

As early as 1964, the FAA required cockpit doors on commercial aircraft be kept locked during flight. [14] In 2002, U.S Congress passed the Arming Pilots Against Terrorism Act, allowing pilots at U.S airlines to carry guns in the cockpit. Since 2003, these pilots are known as Federal Flight Deck Officers. It is estimated that one in 10 of the 125,000 commercial pilots are trained and armed. [46] Also in 2002, aircraft manufacturers such as Airbus introduced a reinforced cockpit door which is resistant to gunfire and forced entry. [47] Shortly afterwards, the FAA required operators of more than 6,000 aircraft to install tougher cockpit doors by 9 April 2003. [31] Rules were also tightened to restrict cockpit access and make it easier for pilots to lock the doors. [48] [49] In 2015, a Germanwings plane was seized by the official co-pilot and deliberately crashed. The European Aviation Safety Agency issued a recommendation for airlines to ensure that at least two people—one pilot and a member of cabin crew—occupy the cockpit during flight. [50] The FAA in the United States enforce a similar rule. [51]

Air marshal service

Some countries operate a marshal service, which puts members of law enforcement on high-risk flights based on intelligence. [31] Their role is to keep passengers safe, by preventing hijackings and other criminal acts committed on a plane. Federal marshals in the U.S are required to identify themselves before boarding a plane, however, marshals of other countries often are not. [52] According to the Congressional Research Service, the budget for the U.S Federal Air Marshal Service was US$719 million in 2007. [31] Marshals often sit as regular passengers, at the front of the plane to allow observation of the cockpit. Despite the expansion of the marshal service, they cannot be on every plane, and they rarely face a real threat on a flight. Critics have questioned the need for them. [53]

Air traffic control

There is no generic or set of rules for handling a hijacking situation. Air traffic controllers are expected to exercise their best judgement and expertise when dealing with the apparent consequences of an unlawful interference/hijack. [54] The pilots, however, are expected to notify controllers via radio or by "squawking" a transponder code of "7500" – the universal code for a hijack in progress. [55] [56] Depending on the jurisdiction, the controller will inform the authorities such as the military who will escort the hijacked plane. Controllers are expected to keep communications to a minimum and clear the runway for a possible landing. [54]

Aircraft shoot down


In January 2005, a federal law came into force in Germany, called the Luftsicherheitsgesetz, which allows "direct action by armed force" against a hijacked aircraft to prevent a September 11–style attack. However in February 2006 the Federal Constitutional Court of Germany struck down these provisions of the law, stating such preventive measures were unconstitutional and would essentially be state-sponsored murder, even if such an act would save many more lives on the ground. The main reason behind this decision was that the state would effectively be taking the lives of innocent hostages in order to avoid a terrorist attack. [57] The Court also ruled that the Minister of Defense is constitutionally not entitled to act in terrorism matters, as this is the duty of the state and federal police forces. [58] President of Germany, Horst Köhler, urged judicial review of the constitutionality of the Luftsicherheitsgesetz after he signed it into law in 2005.


India published its new anti-hijacking policy in August 2005. [59] The policy came into force after approval from the Cabinet Committee on Security (CCS). The main points of the policy are:

United States

U.S. fighter pilots have been trained to shoot down hijacked commercial airliners if necessary. [60] In 2003, the military stated that they exercise this several times a week. [61]

Other countries

Poland and Russia are among other countries that have had laws or decrees for shooting down hijacked planes. [62] However, in September 2008 the Polish Constitutional Court ruled that the Polish rules were unconstitutional, and voided them. [63]

International law

Tokyo Convention

The Convention on Offences and Certain Other Acts Committed on Board Aircraft, known as the Tokyo Convention, is an international treaty which entered force on December 4 1969. As of 2015, it has been ratified by 186 parties. Article 11 of the Tokyo Convention states the following:

Air Canada Flight 797 1983 in-flight fire aboard an Air Canada DC-9-32 near Cincinnati, Ohio, USA

Air Canada Flight 797 was an international passenger flight operating from Dallas/Fort Worth International Airport to Montréal–Dorval International Airport, with an intermediate stop at Toronto Pearson International Airport. On June 2, 1983, the McDonnell Douglas DC-9-32 operating the service developed an in-flight fire behind the lavatory that spread between the outer skin and the inner decor panels, filling the plane with toxic smoke. The spreading fire also burned through crucial electrical cables that disabled most of the instrumentation in the cockpit, forcing the plane to divert to Cincinnati/Northern Kentucky International Airport. Ninety seconds after the plane landed and the doors were opened, the heat of the fire and fresh oxygen from the open exit doors created flashover conditions, and the plane's interior immediately became engulfed in flames, killing 23 passengers who had yet to evacuate the aircraft.

Air rage is disruptive or violent behavior on the part of passengers and crew of aircraft, especially during flight. Air rage generally covers both behavior of a passenger that is likely caused by physiological or psychological stresses associated with air travel, and when a passenger becomes unruly, angry, or violent on an aircraft during a flight. Excessive consumption of alcohol by the passengers is often a cause.

Suicide by pilot event in which a pilot deliberately crashes or attempts to crash an aircraft as a way to kill himself and sometimes passengers on board or people on the ground

Suicide by pilot is an event in which a certified or uncertified pilot deliberately crashes or attempts to crash an aircraft in a suicide attempt, sometimes to kill passengers on board or people on the ground. This is sometimes described as a murder–suicide. It is suspected as being a possible cause of the crashes of several commercial flights and is confirmed as the cause in others. Generally, it is difficult for crash investigators to determine the motives of the pilots, since they sometimes act deliberately to turn off recording devices or otherwise hinder future investigations. As a result, pilot suicide can be difficult to prove with certainty.
