Dave,
That seems probable. Only flew with H. Allen once (July '66), but seem to remember he was large and good-looking. I hesitate to say it in case of error, but IIRC he had been the instructor involved in the Chipmunk practice-forced-landing accident in the May. (The student [Doug X] completed CPL/IR training without further incident, and was later a close colleague of mine for many years.) Perhaps Manoir will remember.
