Hey. By using vehicle miles as the standardization factor for statistical
comparisons, the Space Shuttle should be by far the safest form of
transportation. Right Jim?

When making comparisions, there are 3 metrics. Per hour, per mile, and per
trip. The shuttle is (I suspect) pretty good per mile, iffy per hour and
terrible per trip.

What metric you use depends on why you are using a particular vehicle.
