The CCtCAP customers have to do abort tests to satisfy the NASA Human rating standards.
Is Orion going to do a pad abort, and a Max-Q abort, like SpaceX is required to do?
Or is Orion being held to a different standard, since it is owned by NASA?
If the cost of an SLS booster is on the order of a billion dollars or two (launching once every 2-4 years, it cannot cost any less realistically just in standing army salaries), you can imagine why they would bend any rule to avoid spending that much money on a test.
I cannot imagine an Orion capsule is 'cheap' to 'waste' on an abort test either. But that sounds like an excuse, or else a massive failure, if CCtCAP is cheap enough to be willing to waste boosters and vehicles on tests, vs SLS where it is to valuable to test failure cases. Sort of like the Shuttle...
