RAF(G)FTC
Laarbruchs flying club (last named as the RAF(G) Flying Training Centre) closed with two T67C's, G-BLTU & G-BLPI, and a Robin 180/400 Regent, G-FTIL.
All aircraft went to Wyton's Flying Club where - I beleive - they still are!
They operated on UK CAA Exemptions and Authorisations and so were UK registered.
