I was once the "casualty" on a Whirlwind training flight out of Leconfield. We were doing cliff winching training on Flamborough Head. Suddenly I was lifted off the cliff, set down on top of the Head and the Whirlwind disappeared on a non-exercise mission. I was eventually "rescued" by the Coastguard from hordes of assorted holiday makers who thought I was a real casualty and couldn't understand why I had been unceremoniously dumped after being rescued. Made the Sunday papers.
They did come back for me eventually... they said they wanted the immersion suit back
