Suicide by pilot

This Germanwings Airbus A320 was deliberately crashed into the Alps by a suicidal co-pilot on 24 March 2015, killing all 150 people on board.

This American Airlines Boeing 767-200, registration N334AA, operating as American Airlines Flight 11, was deliberately crashed into the World Trade Center North Tower by hijackers on September 11, 2001, killing all 92 people on board, and about 1600 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.^[1] 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.^[2] As a result, pilot suicide can be difficult to prove with certainty.^[3][4]

Investigators do not qualify aircraft incidents as suicide unless there is compelling evidence that the pilot was doing so. This evidence would include suicide notes, previous attempts, threats of suicide, or a history of mental illness. In a study of pilot suicides from 2002-2013, eight cases were identified as definite suicides, with five additional cases of undetermined cause that may have been suicides.^[5] Investigators may also work with terrorism experts, checking for links to extremist groups to try to determine whether the suicide was an act of terrorism.^[6][7][8]

Most cases of suicide by pilot involve general aviation in small aircraft. In most of these, the pilot is the only person on board the aircraft. In about half of the cases, the pilot was using drugs, usually alcohol or anti-depressants, that would ban them from flying. Many of these pilots had mental illness histories that they had hidden from regulators.^[5]

World War II suicide attacks

During World War II, the Russian aviator Nikolai Gastello was the first Soviet pilot credited with a (later disputed) "fire taran" in a suicide attack by an aircraft on a ground target, although his aircraft had been shot down and was in a rapid partially controllable descent.^[9] In the following years there were more suicide attacks; the best known by military aviators are the attacks from the Empire of Japan, called kamikaze, against Allied naval vessels in the closing stages of the Pacific campaign of World War II. These attacks were designed to destroy warships more effectively than was possible with conventional attacks; between October 1944 and 1945, 3,860 kamikaze pilots committed suicide in this manner.^[10]

	September 26, 1976	Pilot	General aviation	Stolen aircraft	5 (pilot, 4 on the ground)	Following a physical altercation with his ex-wife the night before, Vladimir Serkov made an unauthorized takeoff with an Antonov An-2 (Reg # USSR-79868) from Novosibirsk-Severny Airport and crashed the aircraft into the stairwell of an apartment complex at ul. Stepnaya, д.43 / 1, where his ex-wife's parents lived. After completing two laps around the scene, Serkov attempted to pilot the plane to the parents' apartment where his wife and two-years-old son were visiting. The aircraft pierced the stairwell between the 3rd and 4th floors, and being fueled with 800 liters of gasoline, ignited a large fire inside the stairwell that ultimately spread to damage 30 total apartments. Firefighters were on scene in five minutes, taking 57 minutes to extinguish the blaze. A four-year-old and two six-year-old children were killed at the scene from burns sustained. Another four-year-old child died eight days later as a result of burns sustained. In total, 11 residents were injured as a result of fire burns (four heavy, five medium, two light). Serkov's ex-wife (and her parents) and his toddler son were not injured in the incident. Alcohol was not detected in Serkov's blood and urine tests.[11]		[12]

Published studies

In a 2016 study published in Aerospace Medicine and Human Performance, Kenedi et al. systematically review suicide and homicide-suicide events involving aircraft. They note that "In aeromedical literature and in the media, these very different events are both described as pilot suicide, but in psychiatry they are considered separate events with distinct risk factors." The study (1999-2015) reviews medical databases, internet search engines, and aviation safety databases and includes 65 cases of pilot suicide (compared to 195 pilot-errors in those years) and six cases of passengers who jumped from aircraft. There are also 18 cases of homicide-suicide involving 732 deaths. Pilots perpetrated 13 homicide-suicide events. Compared to non-aviation samples, a large percentage of pilot suicides in this study were homicide-suicides (17%).^[43]

Kenedi et al. note that homicide-suicide events occur only extremely rarely, but that their impact, in terms of the proportion of deaths, is significant when compared to deaths from accidents. They state: "There is evidence of clustering where pilot suicides occur after media reports of suicide or homicide-suicide. Five of six homicide-suicide events by pilots of commercial airliners occurred after they were left alone in the cockpit. This, along with a sixth incident in which active intervention by a Japan Air crew saved 147 lives, suggests that having two flight members in the cockpit is potentially protective. No single factor was associated with the risk for suicide or homicide-suicide. Factors associated with both events included legal and financial crises, occupational conflict, mental illness, and relationship stressors. Drugs and/or alcohol played a role in almost half of suicides, but not in homicide-suicides."^[43]

Prevention

U.S. regulations require at least two flight crew members to be in the cockpit at all times for safety reasons, to be able to help in any medical or other emergency, including intervening if a crew member would try to crash the plane.^[44][45] Following the deliberate crash of Germanwings Flight 9525 on March 24, 2015, some European and Canadian airlines adopted a two-in-cockpit policy^[46][47] as did all Australian airlines for aircraft with fifty or more passenger seats.^[48]
