Regarding that old chestnut that flying is safer than driving - you can't look at it by number of casualties alone. You have to look at the number of hours spent in a plane versus the number of hours in a car, and work the casualties out over that. It is about the probability based on the usage of the airplane versus the usage of the car.
For the amount of time people spend in a plane, the figure would be a lot higher.
For our little aircraft I suspect it is a lot safer to drive. But I don't have figures, someone could work it out though.
