Indeed VX275 I was there too, a great event. OC 2FTS was sadly on leave though he was definitely invited, I understand.
Spooky that a civvy glider 'landed out' on the runway while we were listening to the speeches.
I then ferried an aircraft to Membury to a hangar full of Vikings. An interesting visit... And on the way home we encountered what looked like a civvy G109.
