A thought & probably not a good one but lets say the Iranians have a crashed UAV in their back garden. I wonder, was it a plant? (sorry, pun not intended). Was it deliberatly lost in their general direction? Have they been given something to put them off the scent, a bit of avionic disinformation? WW1 and a bag full of maps were 'lost' in the Middle East and the other side bought it. Are they all banging holes in each others backs and looking the wrong way? Shut up GF?
