If all GA midair collisions were eliminated, ~99% of GA aircraft

That should be ~97%, not ~99%. Corrected number below.

From Nall Report analysis of U.S. NTSB records:

Total fixed wing GA fatalities:
2002: * 518
2003: * 555
2004: * 510
2005: * 491
2006: * 488
Total: 2562

Fatalities due to midair collision:
2002: * * 5

There were 9 fatalities, not 5. There were 5 accidents yielding
fatalities, not 5 fatalities. My misread.

2003: * * 7

Should be 23.

2004: * * 6

Should be 10.

2005: * * 5

Should be 14.

2006: * * 4

Should be 9.

Total: * 27

Should be 65.

Jim,

Does this factor in that there may have been more then one fatality in
an occurance?

For example using simple numbers, if you had 100 planes and 3
accidents that lead to 9 fatalities that would be 3 percent fatality
rate based on takeoffs. (97 percent safety rating)

Second example, if you had 100 planes and 1 accident that had 9 people
in the plane, you would have a 1 percent fatality rate based on
takeoffs. (99 percent safety rating)

I am not sure what the survival rate in a mid air is but to assume
everybody died in a mid air would be statistically incorrect if you
had survivors in any of your cites.
