I remember those B25's arriving in the U.K. I think they were for the film 'Hannover Street' which was being filmed at Bovingdon. The Oil smoke when they started up to position over there was something to see! Jeff Hawke was one of those characters who was involved in a number of 'projects' at this time in aviation history and people like him seem to have faded away. I also vaguely remember his involvement in a job that involved flying a number of Piper Pawnees out to Central Africa, (or was it back from)? Also a DC6 load of ex-RAF Chipmunks to the US in the late 70's.
