Though I haven't seen a SNARK just yet....
The airspace over Iraq must be getting a little crowded with all the UAV's over there serving this user or that. I understand that the USAF wants a review over 'who controls what' -- sounds like they're asking for a latter day Key West Agreement.
As the UAV's tasked by the ground troops gain in size, range & payload they're going to begin 'bumping into' USAF assets.
