During the 1980s, drinking beer in the 8 Squadron crew room at Lossie on a Friday evening (30 seconds after QRA end at 1700 on Friday) when an enormous crash was heard in the Hangar to which the crew room was attached. A quick sprint into the hangar gave us the view of the towing tragedy that had just happened.
The ground crew were towing a Shackleton out of the hangar onto the flight line. A tractor was attached by the towing arm to the tail wheel and the aircraft was to be reversed out into position. Unfortunately on this occasion, the chap in the cockpit had forgotten to take off the parking break: the tractor had pulled on the tail wheel which had collapsed and the aircraft had fallen onto its rear fins and bomb doors.
A cheer for the ground crew was quickly cut short when OC 8 arrived very quickly on the scene from his office in the hangar - death was on his face and we quickly slipped back to the beer call while the Boss debriefed the ground crew. (Before he came into the crew room and debriefed us about standards of behaviour).
The aircraft was fixed by salvaging parts from gate guards and fire dumps around the country (from memory, the Shack at Manston was pillaged for its bomb doors but I stand to be corrected).
