Flight of the Shackleton.
Just found my old ATC Record of Service which details my only flight in a Shack as being fron Kinloss on the 23/08/62 in Shackleton " G " for 3 hours local flying. I don't know if that is enough to identify which frame it was, maybe someone can!
If a Mk3 it would have been 120 Sqn. Just a possibility it might have been a MOTU T4? Can you remember if it had a nose or tail wheel?
Maybe a ISK veteran with a long memory could answer.
