Following ejection from a 14 Sqn Tornado in March 1987 a little way to the east of Wesel (Germany), at least one of the crew (Moloney/Hill) ended up tangled near the top of a tall tree. There was a subsequent, very witty, article in Air Clues about resolving the dilemma involving ladders too short and chain saws too noisy.
I've tried searching archived material with no luck - if anyone can find said article (or even give a first hand narrative, Jon), it would answer in some part Hangarshuffle's question.
