RE: AMA question
While I was stationed at Fort Knox, I had permission to use the airfield there for my RC flying on weekends when the tower was closed. I'd have had to keep a radio with me, and base ops would have let me know about any potential traffic. At that point I'd have had to land. There were a couple of closed runways that I could have easily used and been far out of the way.
I never did take advantage of it. There wasn't anyone to fly with, and it's not as though I could have invited anyone who didn't work on the airfield. Though I had permission and it would have otherwise been a great flying site, I decided that some of the potential risks just weren't worth the enjoyment. I'm not a person who generally enjoys flying alone, anyway.
I'd checked out a couple of the local clubs, neither of which impressed me in the least. I went four years without flying, which in retrospect I sort of regret.
