Well if it is photo-shopped it would be be interesting to see how the original image of the F-4 was obtained..........what are the thoughts?
Low flypast at low speed ( aux air doors) with the power back at idle to avoid any signs of the efflux????
Close formation view from below, again at low speed, but with the power back, etc.....?
Or might it have been simpler to take a picture of an F-4 in the vertical?.
Just asking...
