I don't know whether this will depress you or reassure you, but after 32 years flying I'm still nervous on every flight.
And yet I couldn't do without it and will never give up until I have to.
But then I tell myself that logically, flying is a fundamentally scary business and nerves are therefore hardly surprising.
To my mind the uber cool Sky Gods are either bull****ting or have some intrinsic personality defect, which would make me even more apprehensive about flying with them rather than just on my own or with a non pilot.
On the other hand, as has been remarked, repeated exposure definitely lessens the fear, and to be fair, I suppose that instructors, or professional pilots flying on a daily basis etc, may eventually become immune to a degree.
But then on the other hand again, perhaps a few nerves are a good thing....
