I know, I know ... that wasn't really your question.
If I were you, I'd ask FoxHunter ... he thinks he knows everything (he'll at least be able to tell you what the definition was back in 1936).

That's a P3 mentality. Wheels off to wheels on.. We're not talking block, pay RIG or whatever. Flight is freedom from the worries of our daily lives.
