Damn, where have I been. Well in short, flying in Europe! I have no idea of these TMA and visa requirements, I guess thats why I am here to gleen your knowledge.
Yes I wish to fly and yes I wish to hire aircraft to do such flying. I will of course now phone the relevant parties in the States and find out what this is all about, so thank you for setting me panicing that I've missed such a critical piece of the puzzle.
