I have just found this thread while reseaching a chap (Michael John O'Donohoe) who was at 5 BFTS from August 1942 until April 1943.
After leaving he moved through various units however seems to have become an instructor rather that moving to ops.
I was wondering if you might have come across him during your research, or if you have any further information about his course.
All the best,
Johnnie
