It appeared to me he was under the right wing tip by about a good fifty feet.
Still too close.

"Fifty" ? As in 50 (not 15)? It's difficult to tell because the aircraft leaves
the frame as it passes overhead, but I'd estimate that the aircraft is within a
half wingspan of the ground. So in the case of a Spitfire (wingspan = 36 feet)
we're talking about 18 feet. Entirely too close for the unsuspecting, but then
the cameraman and reporter shouldn't have been walking around on an active
runway. :-)
