I daresay the statistics have already been given on washouts. It would be interesting to know what the cadets were washed out for, lack of aptitude or something else? Jack Currie for example was washed out of Primary for low flying until his instructor appealed to the C.O. (who had caught him) He went on to complete a tour with Bomber Command with a DFC. Maybe the Americans didn’t realise there was a war on?
