Pilot Output Numbers
The documents I have do not show intake figures (only pilot output figures) so I can't add anything to the wastage figures.
I have total output figures of:
Refresher: 598
Arnold: 4370
Towers: 1784
BFTS: 6921
The document adds that 558 American Cadets were trained at BFTS (1943/1944) and that 2081 Fleet Air Arm pilots were also trained under Towers.
(Note: I have not included the figures for observers or WOP/AG's trained at PAA or under Towers)
I have a year by year breakdown of these figures if they are of use.
I am not sure if any of this information is helping you solve your conundrum but I hope it is useful input which may enable you to draw conclusions at some stage in the future
Regards
Pete
