Sure, some of the airline employees are hateful bastards, but I would be too if someone walked up to me and started yelling, so the "never become angry" applies regardless of what class you're flying.
I hate landing in planes; the number of times I've jumped out of the plane far outweighs the number of normal commercial flights I've taken.
Acceleration from a magnitude 5.7 earthquake can be "over 0.1g".
(reference: http://geology.utah.gov/online/pdf/pi-29.pdf)
Acceleration from a car crash, even a minor one, can easily be _several_ g! It's not really comparable, unless the earthquake makes your rack fall over and hit the ground.
Ya'll hear about the geometer who went to the beach to catch some rays and became a tangent ?
