Last year's explosion on SN-10 broke more than any other. It's also spurred NASA to put a pin in plans for the vessel to use Cape Canaveral as a backup launchpad, at least until the company can provide evidence that another blow up on the pad won't damage infrastructure critical to supplies to the International Space Station.

Plans for the primary launchpad for the upcoming Starship rocket is facing lengthy regulatory delays, and the review phase is expected to conclude next week. The company's application to expand its launch site in the area was denied by the Army Corps of Engineers.

The company has been building a secondary launch pad but those plans are on hold. The problem is that the only NASA launch pad that the Dragon Crew is approved to launch from is just a few hundred feet away. The explosion of liquid nitrogen and methane as fuel that is unfamiliar to regulators could damage launch complex 39A. We don't have any more crewed missions until 39A is fixed.

If you had an early failure like we did on one of the early flights, it would be pretty devastating to 39A.

The company has already invested a lot of money in the construction of its platform and is willing to try to harden pad 39A against the forces of both successful and unsuccessful launches. If not years of construction, both of those options would need agency approval.
