Comparing 100,000 flight hours to 100,000,000 miles seems strange to me. If you assumed an average speed of 50MPH, that would be:

    Commercial Aviation (per 100,000 flight hours): 0.022
    General Aviation (per 100,000 flight hours): 1.11
    Motor Vehicle: (per 100,000 driving hours): 0.075
This is data from 2000 though.
