Anybody knows where I can find texts or articles about nap-of-the-earth history?

Answer 1

These links should keep you busy awhile.

I have some pictures taken from 100' over some old "burgs" along Burg Strasse between Mannheim and Darmstadt. It's a rush I got to do several times. We got in the way of an F-? (whatever the air force flew in 75) over the Rhine Valley using his radar. We were below the ridge line, I saw they guy crest the ridge at 3 o'clock. Before I could key up and say Fast Mover he was passing in front of us so close we could see his head in the cockpit. My CO was very cool about it, the Warrant flying #2 was out to get me after that. The CO liked going to Koblenz, over to the Rhine, do a gun run on a tour barge, buzz some llamas, scare the tourists at Rudisheim, buzz the grapes, then buzz the old castles. He always flew at or above the ridge line after that.

Doubt you will find much about what the Air Force uses.
