Airport security repercussions due to the September 11 attacks

Last updated

After the September 11 attacks, there was an immediate call to action regarding the state of aviation security measures as the hijackers involved in 9/11 were able to successfully pass through security and take command of the plane. The existing security measures flagged more than half of the 19 hijackers in 9/11; however, they were cleared to board the plane because their bags were not found to contain any explosives. [1] In the months and years following September 11, 2001, security at many airports worldwide were reformed to deter similar terrorist plots. [2] [3] [1] [4]

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 country's airports. [2] The TSA increased the number of security agents employed from 16,200 to 56,000 and increased their compensation. In addition, they reformed the training for these agents. Prior to 9/11, the security staff was generally undertrained with a reported training time of 12 hours prior to 9/11; afterwards, this training was increased to more than 100 hours. [3] They also implemented verification tests of the training by projecting images of banned objects on machines to see if workers would be able to identify them. [1] The actual process of security screening was revised as well after 9/11. Passenger pre-checks became standard [1] and the percent of baggage screened for explosives increased from an approximate 5% to 100%. [3] In some countries, for example, Sweden, Norway, and Finland, there were no or only random security checks for domestic flights prior to 09/11/2001. [5] On or quickly after September 11, decisions were made to introduce full security checks there. It was immediately implemented where possible, [5] but took one to two years to implement everywhere since terminals were often not prepared with room for it. The TSA also introduced changes on the airplanes themselves, including bulletproof and locked cockpit doors and air marshals which became standard on commercial passenger aircraft. [6] [7]

Increased security on aircraft

Cockpit doors on many aircraft are reinforced and bulletproof to prevent unauthorized access. [8] 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.

Increased 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. [9] Box cutters and similar small knives were allowed onboard 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. [10]

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 in the United States must now have valid government-issued photo ID 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. Non-passengers can also no longer meet passengers at their gate inside the terminal, but rather must wait on the other side of the TSA security check. [11] [12]

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; [13] 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, although this is predominantly in relation to detection of immigration violations by inbound passengers rather than security checking of outbound passengers. [14]

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. [15]

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. [16] [17] Gilmore lost the case, known as Gilmore v. Gonzales , and an appeal to the U.S. Supreme Court was denied.

Privacy issues

Air security and restrictions after the September, 2001 terrorist attacks have helped prevent further attacks from happening, but many Americans have issues with their privacy when traveling. The Computer-Assisted Passenger Prescreening System (CAPPS), was first implemented in the late 1990's by the FFA. CAPPS flagged 6 of the 19 terrorists that were part of the attacks in 2001. The concern with CAPPS was that it also flagged 65,000 other passengers that day. Many Americans viewed this as a threat to their privacy and their information. CAPPS II was created post 9/11 and was created for the same purpose of preventing terrorist attacks and ensuring the safety of Americans. Many Americans had issues with CAPPS II because they believe that it racially and politically profiled passengers. [18] In 2004, the TSA was delayed in testing and developing CAPPS II because they could not obtain passenger data because of privacy concerns. [19]

The Computer-Assisted Passenger Prescreening System (CAPPS) is a counter-terrorism system in place in the United States air travel industry that matches passenger information with other data sources. The United States Transportation Security Administration (TSA) maintains a watchlist, pursuant to 49 USC § 114 (h)(2), of "individuals known to pose, or suspected of posing, a risk of air piracy or terrorism or a threat to airline or passenger safety." The list is used to pre-emptively identify terrorists attempting to buy airline tickets or board aircraft traveling in the United States, and to mitigate perceived threats.

The No Fly List, maintained by the United States federal government's Terrorist Screening Center (TSC), is one of several lists included in algorithmic rulesets used by government agencies and airlines to decide who to allow to board airline flights. The TSC's No Fly List is a list of people who are prohibited from boarding commercial aircraft for travel within, into, or out of the United States. This list has also been used to divert aircraft away from U.S. airspace that do not have start- or end-point destinations within the United States. The number of people on the list rises and falls according to threat and intelligence reporting. There were reportedly 16,000 names on the list in 2011, 21,000 in 2012, and 47,000 in 2013.

<span class="mw-page-title-main">Boarding pass</span> Document provided to an air-travel passenger functioning as a ticket.

A boarding pass or boarding card is a document provided by an airline during airport 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, 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.

Secure Flight is an airline passenger pre-screening program, implemented from August 2009 by the United States Transportation Security Administration (TSA). Secure Flight matches passenger information against watch lists maintained by the federal government. The initial implementation phase of Secure Flight resulted in the complete transfer of responsibility for passenger watch list matching to TSA from aircraft operators whose flights operate within the United States. The second phase of Secure Flight will result in the transfer of responsibility for passenger watch list matching to TSA for flights into, out of, and over the United States.

<span class="mw-page-title-main">American Airlines Flight 11</span> 9/11 hijacked passenger flight

American Airlines Flight 11 was a domestic passenger flight that was hijacked by five al-Qaeda terrorists on the morning of September 11, 2001, as part of the September 11 attacks. The hijacked airliner was deliberately crashed into the North Tower of the World Trade Center complex in New York City, killing everyone still alive aboard the flight and resulting in the deaths of more than one thousand people in the top 18 stories of the skyscraper in addition to causing the demise of numerous others below the trapped floors, making it not only the deadliest of the four suicide attacks executed that morning in terms of both plane and ground fatalities, but also the single deadliest act of terrorism in human history and the deadliest plane crash of all time. The aircraft involved, a Boeing 767-200(ER) with 92 passengers and crew, was flying American Airlines' daily scheduled morning transcontinental service from Boston Logan International Airport in Massachusetts to Los Angeles International Airport in California.

In the United States, border security includes the protection of ports, airports, and the country's 3,017-mile (4,855 km) land border with Canada and 1,933-mile (3,111 km) border with Mexico.

The United States has an extensive air transportation network. In 2013, there were 86 airports in the U.S. that annually handled over 1,000,000 passengers each. The civil airline industry is entirely privately owned and has been largely deregulated since 1978, while most major airports are publicly owned. The three largest airlines in the world by passengers carried are U.S.-based; American Airlines is number one after its 2013 acquisition by US Airways. Of the world's 50 busiest passenger airports, 16 are in the United States, including the top five and the busiest, Hartsfield–Jackson Atlanta International Airport. In terms of cargo, in 2015, eight of the world's thirty busiest airports were in the U.S., including the world's second-busiest, Memphis International Airport, just behind Hong Kong International Airport in Hong Kong. Private aircraft are also used for medical emergencies, government agencies, large businesses, and individuals.

Tianjin Airlines Flight 7554 was a scheduled domestic passenger flight between Hotan and Ürümqi in China's Xinjiang Autonomous Region. On 29 June 2012, an Embraer E190 operating the flight, took off from Hotan at 12:25 pm; within ten minutes, six ethnic Uyghur men, one of whom allegedly professed his motivation as jihad, announced their intent to hijack the aircraft, according to multiple witnesses. In response, passengers and crew resisted and successfully restrained the hijackers, who were armed with aluminium crutches and explosives.

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.
