My little "Record of Service, Form B/Cadets/2", on 18 Aug 61 at No 1 Gliding Centre, RAF Hawkinge, reads:
Solo - L & RH Circuits - Flying time .07 - Launches 3.
I do clearly recall that it was a quite breezy day, and that a Slingsby Cadet TX Mark 3 (**251) went quite fast downwind. Does 3 circuits in 7 minutes count here?
