I overslept. Just got up and saw my Twitter feed.
@elonmusk just had his worst birthday ever, I suspect. But it's a good day for Dick Shelby.

My immediate thought: This makes is a lot harder to sell my thesis that we need to start flying crew ASAP. I haven’t changed my mind, but I’ve never claimed that it would be safe to do so, just that it was important to do so. My second thought: Would the launch abort system have worked for this event? I really am surprised at this.

That's all we can say with confidence right now. Will have more to say following a thorough fault tree analysis.

Thoughts and history from Stephen Smith:
Humanity reached the Moon in 1969, yet failures and fatalities still happen. They always will.
Today I met a 12-year old from a Colorado middle school who had an experiment aboard SpaceX CRS-7. I told her I was sorry she lost her experiment, but she was undeterred. Grinning from ear to ear, she said, “We’ll build another one and do it again!”
As he notes, so will SpaceX.
