Just for the record, this conversion cone is not always a sign of supersonic motion -- just an indication that there is a significant pressure
gradient present, which may happen at subsonic speeds. Having said that, the pic looks like it's shopped.
It is if you look at the cone in the f-18 pic that Har linked and then the B-52 image its obvious as the cone is the same and the clouds in the
background are the same place as well.
