Because testing every sequence would take exponential time relative to the length of the sequence.
For the post-accident simulation, they say "ok since we know we are in this modification of the SR-71, in this phase of the flight, and this accident happens, and this backup fails... ok yeah it looks like that's pretty bad.
- gnoway 13y agoI misunderstood the article I guess. I thought they knew specifically what they were testing, i.e. 'we have altered the airplane this way and we will now do these things.' After the failure, they were able to essentially reconfigure the simulator to match the test parameters, rerun the test and observe the same failure in simulation.
