Photoshopped, methinks. The Gripen appears to be on a takeoff run judging
by the heat distortion of the air immediately aft of the turbine exhaust.
The Gripen's vertical stabilizer obscures part of the Apache's
tailboom thus placing the Apache directly above the turbulence
generated by the Gripen. No ATC or helicopter pilot would permit this
to happen.

Just my opinion

If you like I'd bet you it isn't. I'll pay up if I can't prove it ;-)
So, what do we start the bidding at p;-)
