I recall that military jets sent to investigate Payne Stewart’s plane reported the planes windows were frosted over, but the cause of death was hypoxia. I taught with a police investigator who helped to identify the remains after the crash in northern South Dakota. Very difficult to identify anyone.
Thanks. I remember learning that it is cold at the altitude the Stewart plane was traveling on autopilot with passengers and crew incapacitated but wasn’t sure if it was cold enough to freeze the occupants solid during time until fuel ran out. In any case, they would have died from lack of breathable air first. Sad.
