During sim training was told of a 76 accident where the aircraft hit the dirt and ended up with a lean to the left trapping the co-pilot in his seat. Captain helped rescuers extricate the co-pilot and 45 minutes after the crash the Captain collapsed, died from his head impacting the broom closet, no obvious wound. The switchery above both pilots heads on the C always bothered me, even as short ass used to bang them when wearing a helmet..
