For those that are interested in stats and would like a more realistic odds of dying in a plan crash I found this interesting site:
www.planecrashinfo.com/cause.htm
It quotes the odds of being killed on a single airline flight as 1 in 4.7 million, here is another set of calculations giving a 1 in 11 million chance. As with many things it depends on access to information and how you make the calculations (small aircraft have a much higher chance of accidents, so if you remove them from your stats your chances change significantly). either way you are more likely to be killed at the airport or on your journey to the airport.
I suspect the same is true for sexual assault, on the airplane is not the ideal setting, although there may well be some opportunistic people out there. Ironically the people at higher risk for this are almost certainly not those considered to be children, but older teens and young adults, meaning that statistics about peodophiles are probably completely irrelevant.
