Newt,
Here is the Miliitary Aircraft Accident Summary relating to the non-Battle Flight shooting down of a Jaguar on 25 May 82.
In addition to the aircrew aspects, contributing factors were reliance on pulling a circuit breaker in the rear cockpit as an electrical isolation safety device and the likelihood that, having been pulled and reset so often, contact was made even after the circuit breaker appeared pulled. Also, the groundcrew ran out of bodge tape to secure the Master Arm Switch in the Safe position - and someone else's "ship was spoilt for a ha'porth of tar" !

A bit of banter from the time: 92 Sqn - RAF squadron with the highest number of kills in WWII (317) and since !
