I would not be surprised by anything re US military and Non-Military Intelligence gathering operations.
One thing I would for sure be surprised at would be anyone posting here at pprune have any real idea about the matter at hand.
Those that know....darn tooting will not be posting here.
From my view point....we could have dozens of Drones overhead Iran on a 24/7 basis and I would not be bothered about the Iranian response at all.
Drone surveillance should be an adjunct to Satellite and other methods of intelligence gathering as they are subject to interdiction.
