Boeing decided years ago to certify their in-flight abort using simulation only, and NASA let them.
SpaceX probably can't create a simulation in a few months to not need in-flight abort test because developing a simulation that NASA would consider "proof" probably takes years.
NASA has indicated today they are not going to rush commercial crew [1][3], to not press SpaceX and Boeing into go-fever which NASA has learned is very dangerous.
Because the timing of SpaceX DM-1 (uncrewed demo flight of crewed Dragon 2) depends on ISS visiting vehicle schedule, it might move to the left if visiting vehicle schedule gets reshuffled.
NASA has indicated in today's briefing that crew must be present on station to oversee commercial crew tests [2], so if ISS is de-crewed in December, SpaceX DM-1 can't go in January as scheduled.

- ChuckMcM 8y agoSo somebody stows-away aboard DM-1 and then claims ownership of the ISS by right of possession. :-) That would make for an excellent young adult adventure novel.
- mpnordland 8y agoI'm pretty sure that's when the US Airforce launches the X-37b and claims ownership by repossession.
- stcredzero 8y agoInstead of Repo Man, it's Repo Drone?
- ChuckMcM 8y agoYeah but they can't have anyone on board the X-37b, how can the claim possession? (just keeping the plot line interesting here)
- mpnordland 8y agoI dunno, there's probably a cargo bay in it. Stuff an airman in there with a couple of tanks of oxygen and a rifle.
- 1stcity3rdcoast 8y agoAn excellent follow up to the YA movie Space Camp, which is very fun. I’d read/watch that!
- brandonjm 8y ago> SpaceX probably can't create a simulation in a few months to not need in-flight abort test because developing a simulation that NASA would consider "proof" probably takes years. SpaceX has the benefit of having a bunch of pre-flown rockets lying around. It may be cheaper to refurbish and do a real in-flight abort test than create a suitable simulation.
