Aircraft hijacking

For the fictional character, see Skyjack (Transformers). For the racehorse, see Sky Jack. For the Trumans Water EP, see Skyjacker (EP).

Aircraft hijacking (also known as air piracy or aircraft piracy, especially within the special aircraft jurisdiction of the United States, and informally as skyjacking) is the unlawful seizure of an aircraft by an individual or a group. In most cases, the pilot is forced to fly according to the orders of the hijackers. Occasionally, however, the hijackers have flown the aircraft themselves, such as the September 11 attacks. In at least three cases, the plane was hijacked[1] by the official pilot or co-pilot.[2][3][4][5]

Unlike the typical hijackings of land vehicles or ships, skyjacking is not usually committed for robbery or theft. Most aircraft hijackers intend to use the passengers as hostages, either for monetary ransom or for some political or administrative concession by authorities. Various motives have driven such occurrences, including demanding the release of certain inmates (notably IC-814), highlighting the grievances of a particular community (notably AF 8969), or political asylum (notably ET 961). Hijackers also have used aircraft as a weapon to target particular locations (notably during the September 11, 2001 attacks).

Hijackings for hostages commonly produce an armed standoff during a period of negotiation between hijackers and authorities, followed by some form of settlement. Settlements do not always meet the hijackers' original demands. If the hijackers' demands are deemed too great and the perpetrators show no inclination to surrender, authorities sometimes employ armed special forces to attempt a rescue of the hostages (notably Operation Entebbe).

Record-setting hijackings

"Golden Age"

The so-called "Golden Age" of skyjacking in the United States ran from 1968 through 1979, and into the 1970s in parts of the world, with attacks tapering off after as new regulations made boarding aircraft with weapons extremely difficult.[11]

September 11 attacks

Main article: September 11 attacks

On September 11, 2001, 19 al-Qaeda Islamic extremists hijacked American Airlines Flight 11, United Airlines Flight 175, American Airlines Flight 77, and United Airlines Flight 93 and crashed them into the Twin Towers of the World Trade Center, the southwestern side of the Pentagon, and Stonycreek Township near Shanksville, Pennsylvania (after passengers acted to stop the hijackers; its intended target was either the White House or the U.S. Capitol) in a terrorist attack. All in all, 2,996 people perished and more than 6,000 others were injured in the attacks. This casualty toll makes the hijackings the most fatal in history.

Military aircraft hijacking

Main article: Rashid Minhas

A Pakistan Air Force T-33 trainer was hijacked on August 20, 1971 before the Indo-Pakistani war of 1971 in Karachi when a Bengali instructor pilot, Flight Lieutenant Matiur Rahman, knocked out the young Pilot Officer Rashid Minhas with the intention of defecting to India with the plane and national secrets. On regaining consciousness in mid-flight, Minhas struggled for flight control as well as relaying the news of his hijack to the PAF base. In the end of the ensuing struggle he succeeded in crashing his aircraft into the ground near Thatta on seeing no way to prevent the hijack and the defection. He was posthumously awarded Pakistan's highest military award, Nishan-e-Haider (Sign of the Lion), for his act of bravery.[12][13][14][15][16] Matiur Rahman was awarded Bangladesh's highest military award, Bir Sreshtho, for his attempt to defect to join the civil war in East Pakistan (modern-day Bangladesh).[14]

Notorious hijackings

Dealing with hijackings

Most hijackings will involve the plane landing at a certain destination, followed by the hijackers making negotiable demands. Pilots and flight attendants are still trained to adopt the "Common Strategy" tactic, which was approved by the United States FAA. It teaches crew members to comply with the hijackers' demands, get the plane to land safely and then let the security forces handle the situation. Crew members should advise passengers to sit quietly in order to increase their chances of survival. They were also trained not to make any heroic moves that could endanger themselves or other people. The FAA realized that the longer a hijacking persisted, the more likely it would end peacefully with the hijackers reaching their goal;[18] often, during the epidemic of skyjackings in the late 1960s and early 1970s, the end result was an inconvenient but otherwise harmless trip to Cuba for the passengers.

Later examples of active passenger and crew member resistance occurred when passengers and flight attendants of American Airlines Flight 63 from Paris to Miami on December 22, 2001, teamed up to help prevent Richard Reid from igniting explosives hidden in his shoes. Another example is when a few passengers and flight attendants teamed up to subdue Umar Farouk Abdulmutallab who attempted to detonate explosives sewn into his underwear aboard Northwest Flight 253 on December 25, 2009. Flight attendants and pilots now receive extensive anti-hijacking and self-defense training designed to thwart a hijacking or bombing.[19]

In 2012, six hijackers hijacked Tianjin Airlines flight 7554. Two of the hijackers died from severe injuries sustained during a fight with passengers and crew who attempted to subdue them. A doctor led elderly and children away from the violence. The hijackers had weapons which they used to attack cabin crew and passengers.

Six policemen were on board the aircraft. They helped remove explosives and weapons from the hijackers. A group of resourceful passengers protected the cockpit door using a beverage cart that was rolled in front of the door. The pilot heard screaming and fighting from the cabin. A first class flight attendant was injured trying to stop three hijackers who were in first class from entering the cockpit. Seven passengers were injured during the fights on board the aircraft. It was the first violent hijacking since the 9/11 attacks in North America. When the pilot realized what was happening, he decided to fly the aircraft back to the airport. Once the plane landed, police surrounded it.

Informing air traffic control

To alert air traffic control that an aircraft is being hijacked, a pilot under duress should squawk 7500 or vocally, by radio communication, transmit "(Aircraft callsign); Transponder seven five zero zero." This should be done when possible and safe. An air traffic controller who suspects an aircraft may have been hijacked may ask the pilot to confirm "squawking assigned code." If the aircraft is not being hijacked, the pilot should not squawk 7500 and should inform the controller accordingly. A pilot under duress may also elect to respond that the aircraft is not being hijacked, but then neglect to change to a different squawk code. In this case, the controller would make no further requests and immediately inform the appropriate authorities. A complete lack of a response would also be taken to indicate a possible hijacking. Of course, a loss of radio communications may also be the cause for a lack of response, in which case a pilot would usually squawk 7600 anyway.[20]

On 9/11, the suicide hijackers did not make any attempt to contact ground control to inform anyone about their hijackings, nor engage in any dialogue or negotiations. However, the hijacker-pilot of Flight 11 and the ringleader of the terrorist cell, Mohamed Atta, mistakenly transmitted announcements to ATC, meaning to go through the Boeing 767. Also, onboard flight attendants Amy Sweeney and Betty Ong called the American Airlines office, telling the workers that Flight 11 was hijacked. 9/11 hijacker-pilots Ziad Jarrah and Hani Hanjour aboard Flights 77 and 93 also made a similar error when they mistakenly transmitted announcements to ATC about the hijacking.


Cockpit doors on most commercial aircraft have been strengthened and are now bullet resistant. In the United Kingdom, United States, Canada, Australia, Austria, the Netherlands and France, air marshals have also been added to some flights to deter and thwart hijackers. Airport security plays a major role in preventing hijackers. Screening passengers with metal detectors and luggage with x-ray machines helps prevent weapons from being taken on an aircraft. Along with the FAA, the FBI also monitors terror suspects. Any person who is seen as a threat to civil aviation is banned from flying.

Shooting down aircraft

According to reports, U.S. fighter pilots have been trained to shoot down hijacked commercial airliners if necessary.[21] Other countries, such as India, Poland, and Russia have enacted similar laws or decrees that allow the downing of hijacked planes.[22] However, in September 2008 the Polish Constitutional Court ruled that the Polish rules were unconstitutional, and voided them.[23]


India published its new anti-hijacking policy in August 2005.[24] The policy came into force after the Cabinet Committee on Security (CCS) approved it. The main points of the policy are:

The list of strategic targets is prepared by the Bureau of Civil Aviation in India. The decision to shoot down a plane is taken by CCS. However, due to the shortage of time, whoever – the prime minister, the defense minister or the home minister – can be reached first will take the call. In situations in which an aircraft becomes a threat while taking off – which gives very little reaction time – a decision on shooting it down may be taken by an Indian Air Force officer not below the rank of Assistant Chief of Air Staff (Operations).


In January 2005, a federal law came into force in Germany – the Luftsicherheitsgesetz – that allowed "direct action by armed force" against a hijacked aircraft to prevent a 9/11-type 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 reasoning behind this decision was that the state would effectively be taking the lives of innocent hostages in order to avoid a terrorist attack.[25] 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. See the German Wikipedia entry, or.[26]

The President of Germany, Horst Köhler, himself urged judicial review of the constitutionality of the Luftsicherheitsgesetz after he signed it into law in 2005.

International law issues

Tokyo Convention

The Tokyo Convention states in Article 11, defining the so-called unlawful takeover of an aircraft, that the parties signing the agreement are obliged, in case of hijacking or a threat of it, to take all the necessary measures in order to regain or keep control over an aircraft. The detailed analysis of the quoted article shows that in order of an unlawful takeover of an aircraft to take place, and at the same time to start the application of the convention, three conditions should be met:

  1. The hijacking or control takeover of an aircraft must be a result of unlawful use of violence or an attempt to use violence;
  2. An aircraft should be "in flight" (that is, according to Article 1, paragraph 3 of the Tokyo Convention, from the moment when power is applied for the purpose of take-off until the moment when the landing run ends);
  3. The unlawful act must be committed on board an aircraft (that is, by a person on board an aircraft, e.g. a passenger or crew member. In case of an assault "from the outside", such an offense would be treated as an act of aviation piracy).

However, even without the order of the captain, any crewmember or passenger can take reasonable measures, when he or she has reasonable grounds to believe that such action is necessary to protect the safety of the aircraft, or of people or property therein. The captain may decide to disembark a suspected person on the territory of any country, where the aircraft would land, and that country must agree to that (Articles 8 and 12 of the Convention).

Continuation of the passengers' journey was a provision that first appeared in the Tokyo Convention (Article 11).[27]

Hague Convention

The Convention for the Suppression of Unlawful Seizure of Aircraft (known as The Hague Convention) went into effect on 14 October 1971. Article 1 of the Convention defines the offences to which it applies.

Montreal Convention
