As a low hours PPL I have as much yearning to fly 'interesting' types as the others on this thread. The thing that puts me off is the thought that I'd just be laughed at if I asked someone to let me fly somthing much more challenging. I know this probably wouldn't be the case but I just have visions of calling up and them saying "how many hours?!! - come back in a few years sonny!"
When I have the money (soon, I hope) I'd like to buy a share in somthing interesting, but how many groups honestly want a 70hr tyro like me flying their pride and joy? I guess all the 'spam can driver' comments, although probably mostly said in jest, get into the subconcious more than we realise.
I suppose I just don't want to be embarrassed by being rejected. Perhaps I'd be pleasantly surprised if I just asked...
