In 1965, both 1166 and 2203 ATC Squadrons attended 616 VGS at RAF Henlow. I soloed in T31 WT910 at Henlow on 22nd Feb 1959, and did the advanced course in 1962, after which I became a staff cadet and eventually an instructor at RAF Halton until I retired in 1997 on the Grob Vigilant powered aircraft.
