What's wrong with flying?
I can't speak for Doug, but as for myself, well:
1) Scared of heights. Seriously, I have panic attacks.
2) Scared of flying. Tied to the above somehow. Last time I got into an airplane, I was legally intoxicated when I stepped off. It was either get slobbering drunk, or scream and whine for the whole trip.
Those two reasons alone are why I won't fly anymore unless I'm forced to.
