I have sympathy with the OP as I don't much care for flying either. would agree with earlier poster about riding blindfold in a car. Think it a good idea to register the bumps and vibration we routinely accept in other modes of transport so that any anxiety over the odd bump and rattle is in perspective. Think to be honest what most people like us have is a mild anxiety rather than fear. So put it into perspective as it's not like going over the top in the somme is it? And if the young (and not so young) women in the cc are walking about content what really is there to worry about, let alone fear.
edit: oh, try and get a window seat if you can. The views are amazing and it puts the dynamics in perspective. Bear in mind that the wings will not fall off of their own accord. These things are very very tough and reliable.
