Way back...and I've been PPRuNing for a long time...someone started a thread on Private Flying, saying that he always felt really, really nervous before going flying. He asked how many hours you had to have before that feeling went. Well, guess what! Loads of other people posted..."I've got 500 hours and I still..."; "I've got 2000 hours and...". It was NORMAL to feel that way. Almost everyone did, at one time or another. Loads of people were relieved that it was out in the open, because they'd thought they were the only one, and hadn't dared say anything.
The only time I haven't felt that way from time to time was for a very short time as a new student, when I was foolish enough to completely believe my instructor, who told me that helicopters were really, really safe, that these engines never failed, etc etc. Ignorance was definitely bliss! It wasn't till I learned a bit more, flew a bit more, and...well, lived a bit longer, that I realised he was wrong. Flying's never been the same again...but I'm flying safer al least.
So, cloudchaser, I think you're just NORMAL.
