Montreal - The suicidal action with a stolen plane is not a new phenomenon. Over the years, several incidents occurred in which commercial aircraft were hijacked or stolen for suicidal purposes.

There were no people on board other than the airline's ground employee who died in the incident. There were no victims on the ground either.

The incident is quite similar to the theft of an Air Botswana ATR 42 in 1999. A pilot, who had problems with the management and was not allowed to fly, stole the aircraft at the Gaborone Sir Seretse Khama International Airport. After a few stunts, the plane crashed on two other aircraft that were on the ground.

In 1997, a Boeing 737 of Singapore Airlines subsidiary SilkAir crashed into the Musi River in Sumatra island, Indonesia. According to NTSB, a traumatized pilot crashed aircraft intentionally. There were 104 deaths.

The most recent incident is the crash of Germanwings Flight 9525. On March 24, 2015. The depressed First Officer sent his Airbus A320 against a mountain in the French Alps when the captain was in the toilet. All 150 people on board lost their lives. As a result of the disaster, the European Commission demanded stricter monitoring of the mental state of pilots.

In another incident on March 8, 2014, a Malaysian 777-200ER, Flight 370 disappeared without any trace behind. Some safety experts concluded that the pilot deliberately crashed the aircraft. But there is no clue about the real cause of the incident since the debris of the plane couldn't be found.
