Hi. I'm the person who created the Gathering of Chipmunks at Old Warden this year for the 69th Anniversary.
I'm working on two projects for next year's 70th; one at Old Warden in May and the at RIAT in July.
I was just Googling around to see if the the aircraft from the 1979 RAF Chipmunk training video "Air Experience Flying" still existed and discovered this. Remember Jump Jump John? I'm aiming to have it playing so that all those old AEF students can get to relive it once more.
