Another unfair calculation: 40% of the Space Shuttle have been lost in unsurvivable accidents.

It's better to compare the number of accident divided by the number of flight. For the Space Shuttle, it's 2/135 = 1.4% of the flights. For the manned Soyuz, it's 2/165 = 1.2% of the flight (but both are in very old models).

This is what immediately struck me as well. Boeing has delivered 354 aircraft, 2 of which have gone down with all on board in the last 12 months. It's looking like they have a Comet on their hands.

Assuming they where 1 year in service and doing 1 flight per day, it's more like 0.002% accidents to flights.
