Hi Dave cannot help with 1953 but In
The Gliding Book Chap 3 (Nicholas Kaye Ltd 1965) - Alex Watson writes that in
1963 the Air Cadet Gliding movement was responsible for training
2043 Cadets to A&B standard (3 solo ccts at that time) for a total of
136,345 launches.
There was an A4 pamphlet/booklet called
The Way We Were? published in the 1990's/early 2000's ? which covered Air Cadet Gliding during the wooden years,there may have been some launch/solo statistics in that but the lord only knows where my copy went
Any particular reason for being interested in the 1953 stats ?
cheers /regards LR
