Fair enough. My point was that 33% of the shuttles that were in service are not around anymore, because they’ve blown up killing all astronauts on board. 67% is the percent of the in service shuttles that have survived to the present day. But the words I was using were arguably just an incorrect way of phrasing that, so yeah you kind of have a point.
I can revise my statement to, for any given flight there seems to have been a 1.5% chance that the shuttle would malfunction and kill all the astronauts on board even if they did their jobs perfectly (and specifically for reasons of gross mismanagement of the program as opposed to the already-significant risks inherent to space travel), and that’s too high for a vehicle which was explicitly being pushed hard as a “we can make these flights routine and do tons of them” solution. Sounds better?
