Wow, fabulous video Terry, best on full screen on youtube.
Closest I've been to this is a half hour back seat flight in a Soviet Yak-52.
I wonder if the passenger in the Mustang had his camera strapped to his helmet. I wasn't allowed a camera on the Yak-52 due to safety issues where crashes had been caused by passengers dropping objects which fouled the control cables.
How easy would it be to get to the Heritage Flight Museum in Bellingham WA from Vancouver Island?
