Flying doesn't bother me - however I am a bad lander. That is the part that gets me white knuckled.
Two flights in particular: One, landing in Mexico City in a bad rain and thunderstorm. We bounced while tilting side to side down the runway while landing then it felt like we just kept going and going and weren't going to stop. Two, just the other day. I Was on a AA flight to MIA and as we were landing, the pilot aborted the landing. That is enough to get me nervous, until he came over the intercom and said he aborted because the tower had us too high from the tarmac to land safely. Needless to say I had not much confidence on the second try, but we landed just fine.
