I really don't know where my fear of flying has come from, I flew everywhere as a kid, had loads of family holidays and it didnt bother me in the slightest. I've never really had a bad flight, had some turbulence, been close to some pretty epic storms, but my fear of flying gets worse and worse every time that I fly these days, peaking at take-off and landing.
Worst experience I had was on a flight to Antigua with the whole family for my wedding, we get about 4 hours in, and there is water all over the floor of the passenger cabin, the carpet is utterly soaked through. Pilot comes on the tannoy (I'm paraphrasing here) 'As some of you will have noticed, we have a small leak in the so and so system, and there is some build up of water on the floor of the passenger cabin, we have been in contact with our engineers back in London and they assure us its nothing at all to worry about, and we are good to continue to our journey' - First off, if its nothing to worry about, did you need to tell me that you'd checked with your engineers in London? Secondly, we're 4 hours in, we're over the middle of Atlantic, if it was an issue, what could you possibly do about it anyway?
The other bad experience I had was coming in to land at Vegas for the honeymoon, pilot warned us at the start of the flight that the landing was going to be a bumpy one due to the air currents coming up off the desert at this time of year, my god. First off, the approach, lets fly past the airport and do a U-Turn, seriously the aircraft was tilting so much that from my window seat at the back of the plane all I could see was ground, not fun. Then, we're coming in, we're bouncing all over the place, more worryingly we are wobbling left to right constantly, the woman behind me screams 'oh my god we're going to crash' and I'm sitting in my seat clutching onto the arm rests with all I've got praying we dont.
I find my fear irrational and pathetic, it annoys me that I'm so worried about such a statistical longshot, but at the same time, it does still bother me.
