I shot the title photo of the Lone Star Flight Museum's B-17 while leaning out the side port of the museum's B-25 Mitchell. This photo was out over the Gulf of Mexico, off Galveston.
My cousin (by marriage) Gumby is driving the Flying Fort. He is the Museum's Chief Pilot. Standing behind him is Tuna, an ex-USAF pilot with substantial flight time in the F-4 Phantom and F-117 Nighthawk.
Gotta tell you ... doing this is fun!
