Spitalgate was the home of 644GS - a weekend school commanded by Flt Lt Albert Johnson. No 2 Gliding Centre moved from Kirton Lindsey to Spitalgate in November 1965. Peter Bullivant was one of the staff instructors, having previously been CO of the Gliding School at RAF Henlow (can't remember its number). George Crump was never on the staff of 2GC but was CO of 633 GS at RAF Cosford.
I have some photographs, surprisingly few, which I shall dig out and post.
