Suicide by pilot

Suicide by pilot is an aviation event in which a pilot deliberately crashes or attempts to crash an aircraft as a suicide act, with or without the intention of causing harm to passengers on board or people on the ground. If others are killed, it may be considered a type of murder–suicide. It is suspected to have been a possible cause in several commercial flight crashes and has been confirmed as the cause in other instances. Determining the motives of pilots can be challenging for crash investigators, as pilots may intentionally disable recording devices or engage in other actions to impede future investigations. Consequently, definitively proving pilot suicide can be difficult.
Investigators do not classify aircraft incidents as suicides unless there is compelling evidence indicating that the pilot intended to commit suicide. This evidence may include suicide notes, past suicide attempts, explicit threats of suicide, or a documented history of mental illness. A study conducted on pilot suicides between 2002 and 2013 identified eight cases as definite suicides, along with five additional cases of undetermined cause that may have been suicides. In some cases, investigators may collaborate with terrorism experts to investigate potential connections to extremist groups, aiming to ascertain whether the suicide was an act of terrorism.
A Bloomberg News study conducted in June 2022, focusing on crashes involving Western-built commercial airliners, revealed that pilot murder-suicides ranked as the second most prevalent cause of airline crash deaths between 2011 and 2020. Additionally, the study found that deaths resulting from pilot murder-suicides increased over the period from 1991 to 2020, while fatalities due to accidental causes significantly decreased. Notably, if China Eastern Airlines Flight 5735 is confirmed to be an intentional act, it would indicate that deaths caused by intentional acts have surpassed all other causes since the beginning of 2021. However, most cases of suicide by pilot involve general aviation in small aircraft, where typically the pilot is the sole occupant of the aircraft. In approximately half of these cases, the pilot had consumed drugs, often alcohol or antidepressants, which would typically result in a ban on flying. Many of these pilots have concealed their mental illness histories from regulators.
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. 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 and , 3,860 kamikaze pilots committed suicide in this manner.

Published studies
A 2016 study published in Aerospace Medicine and Human Performance analyzed suicide and homicide-suicide events involving aircraft. They state, "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." In the years 1999–2015 the study found 65 cases of pilot suicide (compared to 195 pilot errors) and six cases of passengers who jumped from aircraft. There were 18 cases of homicide-suicide, totaling 732 deaths; of these events, 13 were perpetrated by pilots. Compared to non-aviation samples, a large percentage of pilot suicides in this study were homicide-suicides (17%).
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 tries to crash the plane. Following the deliberate crash of Germanwings Flight 9525 on March 24, 2015, some European, Canadian and Japanese airlines adopted a two-in-cockpit policy as did all Australian airlines for aircraft with 50 or more passenger seats.
