Was on the Board of the Victor Tanker accident in the North Sea when a Buccaneer took the tail off. Only the Captain survived. The rear crew were up on the roof as the aircraft bunted. Its doubtful whether ejection seats as then fitted (but not for the rear crew) would have helped as the Co-pilot was unable to reach either handle. This was because the seats were fitted with the small solid handle rather than the larger loop. The Captain may have pulled his handle but it is more likely the top latch broke and the seat then fired.
The Victor was fitted with an abandon aircraft switch on the Captain side panel which lit lights in front of the rear crew and also depressurised the cabin so the door could be opened. Trouble was Fred H-P thought his aircraft would always be hangared so did not make them waterproof. Caused short circuits in that circuit among others. Had it come on once. To quote OC units comments on the AIR, "Fortunately the experienced crew members questioned the light rather than abandon in spite of the greatly increased noise level".
