Aeroflot Flight 593 (1994)
The Airbus A310 crashed in 1994 due to improper pilot handling. This led to revised pilot training and improvement in schooling and communication. Back then, even though it wasn’t technically permitted, people could visit the cockpit if they knew the pilot. During this detrimental event, a son and daughter visited his father in the cockpit during the flight. For some reason, the father allowed his children to sit in the seats and hold onto the controllers. Even though the plane was on autopilot, the son hit the controllers too hard, sending the plane to a fatal angle. The aircraft spun out of control and crashed to the ground (Simple Flying).
