Interesting thread - sort of related but I witnessed the Raven mishap at Upper Heyford back in 1992. Was stood outside the factory in Bicester where I was working and saw it pass overhead trailing flame before disappearing into cloud. About an hour later we heard reports on the local radio that an aircraft had crashed onto a car park just outside the town. Fortunately the crew got out fine but a bloke in the car park needed a change of trousers & underpants, having seen the plane spinning groundward and flinging himself under a parked car to avoid the blast + debris.
