well, the mechanics of it dont bother me at all, as I WAS in aeronautical engineering for a year, and have since gone to civil engineering.
I've been in a lot of different situations where nerves are tested (in athletics though), but I'm just worried that once it gets off the ground a LITTLE bit, it'll cartwheel... NOT a good way to start off.
But I'll be fine, I'm sure, just a little bit nervous about the whole thing right now.

Thanks for the replies and the words of encouragment!
