Airport security repercussions due to the September 11 attacks

Last updated

After the September 11 attacks, questions were raised regarding the effectiveness of airport security at the time, as all 19 hijackers involved in 9/11 managed to pass existing checkpoints and board the airplanes without incident. In the months and years following September 11, 2001, security at many airports worldwide was escalated to deter similar terrorist plots. [1]

Changes in airport security

Prior to September 11, 2001, airport screening was provided in the U.S. by private security companies contracted by the airline or airport. In November 2001, the Transportation Security Administration (TSA) was introduced to take over all of the security functions of the FAA, the airlines, and the airports. [1] Among other changes introduced by TSA, bulletproof and locked cockpit doors became standard on commercial passenger aircraft. [2]

In some countries, for example, Sweden, Norway, and Finland, there were no or only random security checks for domestic flights in 2001 and before that. [3] On or quickly after September 11, decisions were made to introduce full security checks there. It was immediately implemented where possible, [3] but took one to two years to implement everywhere since terminals were often not prepared with room for it.

Improved security on aircraft

Cockpit doors on many aircraft are reinforced and bulletproof to prevent unauthorized access. [4] Passengers are now prohibited from entering the cockpit during flight. Some aircraft are also equipped with CCTV cameras, so the pilots can monitor cabin activity. Pilots are now allowed to carry firearms, but they must be trained and licensed. In the U.S., more air marshals have been placed on flights to improve security.

Improved security screening

On September 11, hijackers Khalid al-Mihdhar, Majed Moqed, and Nawaf al-Hazmi all set off the metal detector. Despite being scanned with a hand-held detector, the hijackers were passed through. Security camera footage later showed some hijackers had what appeared to be box cutters clipped to their back pockets. [5] Box cutters and similar small knives were allowed on board certain aircraft at the time.

Airport checkpoint screening has been significantly tightened since 2001, and security personnel are more thoroughly trained to detect weapons or explosives. In addition to standard metal detectors, many U.S. airports now employ full-body scanning machines, in which passengers are screened with millimeter wave technology to check for potential hidden weapons or explosives on their persons.[ citation needed ] Initially, early body scanners provoked quite a bit of controversy because the images produced by the machines were deemed graphic and intrusive. Many considered this an invasion of personal privacy, as TSA screeners were essentially shown an image of each passenger's naked body. Newer body scanners have since been introduced which do not produce an image, but rather alert TSA screeners of areas on the body where an unknown item or substance may be hidden. A TSA security screener then inspects the indicated area(s) manually. [6]

Identification checks

On September 11, some hijackers lacked proper identification, yet they were allowed to board due to being on domestic aircraft. After 9/11, all passengers 18 years or older, must now have valid government-issued identification in order to fly. Airports may check the ID of any passenger (and staff member) at any time to ensure the details on the ID match those on the printed boarding pass. Only under exceptional circumstances may an individual fly without a valid ID. If approved for flying without an ID, the individual will be subject to extra screening of their person and their carry-on items.[ citation needed ] TSA does not have the capability to conduct background checks on passengers at checkpoints. Sensitive areas in airports, including airport ramps and operational spaces, are restricted from the general public. Called a SIDA (Security Identification Display Area) in the U.S., these spaces require special qualifications to enter. [7]

A European Union regulation demanded airlines make sure that the individual boarding the aircraft is the same individual who checked in his or her luggage; [8] this was implemented by verifying an individual's identification both at luggage check-in and when boarding.

Some countries also fingerprint travellers or use retina and iris scanning to help detect potential criminals. [9]

Criticism

With regard to the 2015 Germanwings flight 9525 crash incident, a suicide by pilot where the captain was unable to regain access to the flight deck, some have stated that security features added to commercial airliners after 9/11 actually work against the safety of such planes. [10]

Lawsuit

In 2003, John Gilmore sued United Airlines, Southwest Airlines, and then-U.S. Attorney General John Ashcroft, arguing that requiring passengers to show identification before boarding domestic flights is tantamount to an internal passport, and is unconstitutional. [11] [12] Gilmore lost the case, known as Gilmore v. Gonzales , and an appeal to the U.S. Supreme Court was denied.

Aircraft hijacking, is the unlawful seizure of an aircraft by an individual or a group. Dating from the earliest of hijackings, most cases involve the pilot being forced to fly according to the hijacker's 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 hijacked by the official pilot or co-pilot; i.e., the Lubitz case.

Security theater is the practice of taking security measures that are intended to provide the feeling of improved security while doing little or nothing to achieve it. Examples include tightened airport security measures or other public transport security measures after major terrorist attacks.

Boarding pass

A boarding pass or boarding card is a document provided by an airline during check-in, giving a passenger permission to enter the restricted area of an airport and to board the airplane for a particular flight. At a minimum, it identifies the passenger, the flight number, and the date and scheduled time for departure. A boarding pass may also indicate details of the perks a passenger is entitled to and is thus presented at the entrance of such facilities to show eligibility.

Hand luggage

The term hand luggage or cabin baggage refers to the type of luggage that passengers are allowed to carry along in the passenger compartment of a vehicle instead of a separate cargo compartment. Passengers are allowed to carry a limited number of smaller bags with them in the vehicle, which typically contain valuables and items needed during the journey. There is normally storage space provided for hand luggage, either under seating, or in overhead lockers. Trains usually have luggage racks above the seats and may also have luggage space between the backs of seats facing opposite directions, or in extra luggage racks, for example, at the ends of the carriage near the doors.

Secondary Security Screening Selection

Secondary Security Screening Selection or Secondary Security Screening Selectee, known by its initials SSSS, is an airport security measure in the United States which selects passengers for additional inspection. People from certain countries are subject to it by default. The passengers may be known as Selectee, Automatic Selectee or the Selectee list. The number of names on the list fluctuates and is a secret, although the Transportation Security Administration apparently says there are tens of thousands of names on it.

American Airlines Flight 11 9/11 hijacked passenger flight; hit the North Tower of the World Trade Center

American Airlines Flight 11 was a domestic passenger flight that was hijacked by five al-Qaeda terrorists on September 11, 2001, as part of the September 11 attacks. Mohamed Atta deliberately crashed the plane into the North Tower of the World Trade Center in New York City, killing all 92 people aboard and ensuring the deaths of 1,402 people at and above the aircraft's impact zone. The aircraft involved, a Boeing 767-223ER, registration N334AA, was flying American Airlines' daily scheduled morning transcontinental service from Logan International Airport in Boston to Los Angeles International Airport in Los Angeles.

Germanwings Flight 9525 2015 deliberate crash of an airliner in the French Alps

Germanwings Flight 9525 was a scheduled international passenger flight from Barcelona–El Prat Airport in Spain to Düsseldorf Airport in Germany. The flight was operated by Germanwings, a low-cost carrier owned by the German airline Lufthansa. On 24 March 2015, the aircraft, an Airbus A320-211, crashed 100 km north-west of Nice in the French Alps. All 144 passengers and six crew members were killed. It was Germanwings' first fatal crash in the 18-year history of the company.

Suicide by pilot Aviation disaster in which a pilot intentionally crashes the aircraft to hurt themselves or others

Suicide by pilot is an aviation disaster 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.

Airport privacy involves the right of personal privacy for passengers when it comes to screening procedures, surveillance, and personal data being stored at airports. This practice intertwines airport security measures and privacy specifically the advancement of security measures following the 9/11 attacks in the United States and other global terrorist attacks. Several terrorist attacks, such as 9/11, have led airports all over the world to look to the advancement of new technology such as body and baggage screening, detection dogs, facial recognition, and the use of biometrics in electronic passports. Amidst the introduction of new technology and security measures in airports and the growing rates of travelers there has been a rise of risk and concern in privacy.

TSA PreCheck U.S. Transportation Security Administration traveler program

TSA PreCheck is a Trusted Traveler program initiated in October 2011 and administered by the U.S. Transportation Security Administration that allows selected members of select frequent flyer programs, members of Global Entry, NEXUS, and SENTRI, members of the US military, and cadets and midshipmen of the United States service academies to receive expedited screening for domestic and select international itineraries. As of March 2019, this program was available at more than 200 airports.
