Elon posted multiple tweets last night, primarily relating to SpaceX. So far the SpaceX team has been unable to identify the cause of the recent launch pad explosion. He said it is the most difficult failure investigation they have ever experienced. And the future of SpaceX rides on figuring it out and implementing changes to ensure it doesn't happen again. I don't see how they can proceed with their launch schedule until they do. So I really feel for the guy and the entire SpaceX team. They are dealing with an existential threat to the company. They have to figure out what happened before they fuel the rockets for the next launch. Time is money and every day of delay is costly. Their insurance premiums could skyrocket.
The Tesla Motors team is proceeding with AP V8 and AP 2.0 whether Elon makes his blog post or not.
