I never used to bother about flying when I was younger. Twice yearly trips from and to bahrain during the summer months every year for 6 years was a doddle.
However since I got older I dislike flying; not because of the sensation or turbulence or anything like that, but because I'm more aware of the fact that should even a small thing go wrong, the chances of turning into a plummeting ball of fire, before smashing into the ground from 35,000 feet is only a few maintenance dollar hours from the lowest bidder away.
Seriously, since I learned to drive and maintain my own vehicle following some of the shoddy jobs auto mechanics have made, I have a whole new under-appreciation for my faith in other people doing the job right.
Besides which, if I have an accident in my car (ignore all the usual statistics for a moment) or it breaks down whilst I'm in it, I'm not going to fall out of the sky. Unless something really strange is going on
Irrational, maybe...
