In any randomized event, preceding events do not effect future
probabilities. If the risks of crashing a plane are 1 out of 10,000
flights, you are not risk free on the 10,001st flight.

The honest way to measure safety across various modes of transporation is
not to use the miles travelled metric, as this is hopelessly skewed. It
should be per trip.

What I think you all should be advocating in adjusting the statistics is
to remove acrobatic flying, which has a higher accident rate than GA and
makes GA look more dangerous than it actually is.
