During the 2012 Boeing 727 crash experiment, a flight crew took off in the Boeing 727 that was to be crashed and flew it to a pre-selected desert site before safely parachuting from the airstair, as the Mexican government required that the plane be flown by a human crew for part of the experiment, especially as the aircraft's route to the crash site passed over populated areas. The 727 was then deliberately flown into the ground under remote control.[5]
