I absolutely believe you. I've never been afraid of flying, but now that I'm older, every single time I now find myself thinking, “Jesus, this is a really heavy vehicle, is it really going to become airborne before we run out of runway?” Always seems like a miracle of human ingenuity.
The two shortest runways, it seemed to me, that I ever flew out of, were that small secondary airport at Toronto, you know the one, on the island. And the old Hong Kong airport, before they built the new one. Both sphincter-tightening moments, for me. You see the water coming up swiftly, even from the passenger porthole! You think to yourself, “Well… I think it's time we were in the air, now. Yes — it's definitely time.” Wonder if you ever flew in and out of those two?
Can't imagine what it's like being up front. But at least you're in control. We're not!
