Based on this information, I think it would be most interesting to see a
couple of other statistical perspectives. It appears that the "event" rate
on the 2nd generation 737 is significantly lower than on the A320.
Therefore, it would be very interesting to scatterplot the hull losses with
the age of the aircraft. Barring that, it would be nice to compare the hull
losses of the 2nd generation 737 to the A320, as the ages would likely be a
closer match overall.
