617 VGS are no more...used to be at Manston I think.
622,
617VGS Did a grand tour of SE England, starting at Hendon, followed by Bovingdon and finally Manston. Was a CI (G1, C & B Wood, B Glass) at Manston '81-'87.
Have great friends from those days, think the current Air Cadet Gliding sch-mozzle nothing short of farcical!
'866 (competition number, not VGS!)
