Not just Colerne and Henlow but a number of other well known historic sites: Chalgrove (believe this sale/move of Martin Baker was mentioned on the Meteor thread), Amport House and Prince William of Gloucester Barracks (RAF Spitalgate).
PW of G barracks...........aaaargh, I did my basic there! RCT, not RAF. Don't know why it saddens me.....it just does! It wasn't such a bad place. Ah well.
