Aerbabe,
get hold of a copy of Richard Bachs 'gift of wings'
Theres a story in it 'Loops, voices and the fear of death' which says it all far better than I could explain it. It all boils down to our fear of the unknown, which is a survival trait. He takes the example of jumping off a high diving board as a child, running through the emotions and fears that you feel until you take the plunge and then the rush that you get once you've done it.
Anyone who says that they've never been afraid or concerned whilst flying is either lying or someone you should not get into an aeroplane with.
Don't forget every thousand hour ace started off as a green sprog. learn from those around you, don't get discouraged and if in doubt ask.
And yes I have been scared F@rtless, but I have also been elated and enchanted in equal or greater measure
