??? Stealth fighters escorting drones on a reconnaissance mission? Shouldn't the fighter jets just do the recon mission if the drones are 'hackable' as you presume?
Search for any airbase if it has an expeditionary squadron from Beale AFB. Most likely (just my guess) it's from Kandahar. The RQ-170 is there. So does it means the U-2 is there? I don't know, but the RQ has been spotted where the TR-1 home base (beale).
My God. I've been to Tyndall AFB (don't ask how I got in there) it was 40-50 degrees raining, parked in a hanger like the one below (thinner though) with two F-15s. I didn't see anything draining down the Raptor. Touched it and I didn't feel a drop of RAM draining off the jet.
You're just pulling these things out of your *** aren't you?
Actually the earliest development of the F-117 was in the late 1970s. Search up Have blue and Senior Trend.
