I read once that a B 17 got hit over Germany which tore the tail section off. Rear gunner was unable to bail out and rode it down. Apparently the wind drag on the empennage plus a relatively soft landing in trees enabled him to walk away and spend the duration in a stalag. Talk about lucky!
06/10/1990 British Airways BAC-111 Oxfordshire, England On a flight from Birmingham, England to Malaga, Spain, at FL 173, a large section of windshield fell away from the aircraft. The decompression pulled the captain out from under his seatbelt. Despite trying to hold onto the yoke, the captain was sucked out into the opening. A steward in the cockpit was able to grab hold of his legs. Another steward was able to strap himself into the vacant seat and aid in holding onto the captain's legs. The copilot wearing full restraints made an emergency landing at Southampton. The captain remained half way out of the aircraft for 15 minutes and suffered only frostbite and some fractures. Improper bolts used to replace the windshield two days earlier resulted in the accident.
