Shotwell's response is in the best interests of her company, but SpaceX is (as well as Boeing) woefully behind on a reasonable timeline to reach human-rated flight for both their rocket and crew module.

We should have learned from both the early Apollo program, and the Shuttle failures, that human lives shouldn't be treated as expendable capital in this industry.

Both SpaceX's current announcement, and the US Gov's desire to put humans on the first flight SLS flight, are deeply troubling in that regard.
