It’s by no means the first case of someone jumping from an aircraft and sadly, no doubt it won’t be the last, in spite of any procedural changes caused by legislation.
Years ago I was told the story of a suicidal father who booked a “sight seeing” flight in a four seater for himself and two small children and once airborne tried to take control and dive the aircraft into the ground. The pilot, who was one of my instructors at the time, eventually had to subdue the man using the blunt end of the portable fire extinguisher. I can’t imagine how traumatic this would have been for all concerned.
