On June 15, 1991, a pilot flew his Bushby Mustang II from Altenrhein to Saanen, Switzerland in order to carry out a sightseeing alpine flight with his girlfriend the next day. On this flight, he did an unbelievably stupid thing.
DISCLAIMER: The VL-3 is NOT the accident aircraft. I don't have a Bushby Mustang in the simulator, so I chose the VL-3, my favorite aircraft. There's a plug for the VL-3 in the commentary.
