Paul, I don't think you have anything to worry about riding in an airplane really, yes, they do put some unnatural g-forces on the body, but they are quite safe when one considers the risk of driving!
Airline pilots are highly trained with hundreds of hours...automobile drivers get basically zero hours of training...all you need to do to get a license these days is remember a few drunk-driving statistics, and what a few signs mean! The numbers tell it all! Only a few hundred a year die in planes, but over 38,000 die in automobiles every year! Worried about that toilet motor? Well, you ought to be more worried about that redneck behind you in the old pickup truck that repaired his brakes himself using water hose and used cooking oil!
I am one that enjoys investigating failures...well, it's part of my job as an electronics technician. In electronics, perhaps 50 percent of the failures are due to bad engineering, another 25% due to poor craftsmanship, and another 25% due to user abuse. China however is moving the bar around...it's now 50% bad engineering, and 50% poor craftsmanship...usually the stuff breaks before the customer has a chance to abuse it nowadays!!!!
As far as airline crashes go, well many of them are due to mechanical failure, or external forces (weather, terrorism) Pilots are trained pretty good, and many of them end up landing planes without incident when components malfunction. The good ones that do this, well, you don't hear about them because they are not newsworthy. They quietly flip a switch and kick in an auxilary or something, and you are sitting there in the cabin relaxing as you cruise away blissfully.
The exact opposite is true with automobiles, where the drivers have zero qualifications, and most crashes are caused by operator error!!!
As you can probably tell by now, I'm the exact opposite of most people. The average person is more apprehensive about flying than they are about driving. Being a bit autistic, I tend to look at things in a more logical approach, and the statistics for automobile crashes is pretty frightening to me! Enough that it makes me quite nervous every time I must hit Interstate 95 and trek up to DC among all the manics out there talking on phones, and what not in their cars, swerving, cutting people off, tailgating, speeding, and whatever else....you don't see airplanes doing that crap, that's for sure!!! I take automotive safety very seriously, but unfortunately, the rest of the country doesn't. I wish we put as much a fraction of a percentage into making our roads as safe as we do our skies!
We had 33 people killed senselessly at VA Tech last spring. We are still talking about it, and the site where it happened is going to be forever memorialized. In your home state this weekend, chances are that many people will be picked off the highway and nary a word will even be printed about it outside of the police reports. All the talk about it will be "inconvenience" the resulting traffic jams caused. The memorial? just a few tire marks on the road that will be covered up with the next coat of asphalt.
...it just staggers my mind how casual we are about automotive carnage!
