Sort of unrelated, however, I'll point out a "Cheat" one can do when capturing fields.
I was flying a C47, airmen called out that Field XX didn't have ack down yet, and a bomber was OTW. So I flew my C47 to the nearby mountains, found a nice little spot in a deep valley, and landed on a slope going up, gently, and turned the C47 around so I was pointed downhill, shut engines off and waited. No one could see me unless they flew directly overhead. So I waited. Had a cup of joe, had a chew, 20 minutes later airmen called out for a C47..."Be there is 1 min" I said, fired up the engines, lifted off easily (aircraft pointed down hill) and captured airbase 45 seconds later.
I don't think one should be able to land on any terrain other than the terrain around the airfield, or someone like myself might exploit it!
