To have an equivalent fatality rate per passenger-mile, you'd need about 7,500 commercial aviation fatalities in the US per year (two and a half 9/11s, ~60 fully loaded 737s).

Per hour would be lower of course, maybe 1/10th as many just judging by "cruise speed." I couldn't find good hour-wise data.
