Well not really, because the right way (IMHO) to measure safety is in terms of "safe trips" or "safe hours", not miles. You cover miles a lot faster in an airplane (usually). The commonly used "per mile" stats are suspect becuase it is a completely different kind of travel in most cases. For example even the whole car thing gets thrown off more when you consider that most fatal car accidents happen in intersections and on two lane roads where limited access highway travel probably racks up the most miles traveled. > just to be the young-buck thing.

It could be that women have a strong survival instinct and probably won't do something like fly into 600ft ceilings at dusk into busy airspace in a single prop airplane, because it just doesn't make sense if survivability is more strongly valued than say making it to a meeting or getting home tonight. Perhaps to a woman, the more important statistic might be the frequency of fatalities under different weather conditions! But, more than likely the real reason is just that women more readily ask for directions and then actually listen and follow them. :-) BTW, Congratulations on hitting 200h!

On entering Sweden, I was lulled into the belief "Bah, they're paranoid.", as "nothing ever happened" on the signs I saw and read and not.

First, while flying on a scheduled air carrier is much safer than driving per passenger mile, flying with a private pilot is seven times more dangerous than driving -- in other words, it's roughly comparable to riding a motorcycle. Gender equality does not rule in private flying. While a male driver is only about twice as likely as a female driver to get into a fatal car accident, a male private pilot is eight times more likely as a female private pilot to get into a fatal plane accident. That suggests that you're safer per mile flying in a small plane with a female private pilot than you are driving in a car with a man. It also suggests that flying accidents are much more under the pilot's control than driving accidents, since the gender gap is so much larger. Some day I'll do the proper research to see if the numbers I've heard are accurate. We know that it's young male drivers who cause the most car accidents, but many private pilots are older, so it's unlikely just to be the young-buck thing. My guess is that (on average) men just have a harder time admitting they're wrong than women do. Fatal plane accidents can happen gradually, as the result of a long chain of bad decisions and other problems -- there are often many points where the pilot could have saved him or herself by turning back, waiting a couple of hours for better weather, choosing a different altitude or route, making an extra fuel stop, etc. Maybe women as a group are just better at doing that kind of thing.

Why the hell not??? They indicate nothing about what level of experience is really the most dangerous: the real killing zone could be at 100 hours, or 900, but we cannot tell. To take a different example, if I could show that more people die every year from falling off chairs than from high-altitude mountain climbing without oxygen, would that prove that sitting on a chair is more dangerous? > That's no reason to let those _same_ accidents repeat themselves > over and over again. I agree absolutely -- it is absolutely critical for everyone, pilots, car drivers, joggers, cyclists, etc. -- to know what the dangers are.

OK, I'm obviously sleepy today after my flight last night. Everywhere I wrote "three times", replace with "a third", and the math might actually make sense.
