you should read Skunk Works if that interests you.
I'm pretty sure there's a story about that test pole in which the radar guys thought they spotted it, but in reality a bird had landed on it. Someone honked a truck horn, the bird flew off, and the radar signature of the plane on the pole disappeared again.
"Keith Beswick, head of the flight test operations, designed a coffee mug for his crew with a clever logo showing the nose of Have Blue peeking from one end of a big cloud with a skunk's tail sticking out the back end. Because of the picture of the airplane's nose, security classified the mugs themselves as top secret. Beswick and his people had to lock them away in a safe between coffee breaks."
There's also a story in there about one of the radar tests at Groom Lake where they had radar techs in a mobile trailer and they were going to fly Have Blue right over them and the techs were supposed to call it out when they spotted it on their scopes. Well when one of them saw it on the screen they stepped outside the trailer and it was the chase plane going by. The F117 prototype was already off in the distance having flown right over the radar station without being seen.
Sat on the F117 once on one of it's trips back from Saudi. Stop in for a fueling stop before heading back across the atlantic and that one pictured was struck by lightening while landing. Pretty cool airplane.
