Yes, SpaceX will eventually have a lives-lost incident, and it will be ugly. How the market / investors take it I have no prediction for.

But NASA has had several of those types of accidents over the years, so the waterfall / perfection model isn't immune to them, either. The two shuttle losses were due to bureaucracy that defeated NASA's safety culture, and the Apollo 1 debacle showed that their vaunted safety and technical reviews actually could miss something very important - several things simultaneously, in fact.

I think it's unfair to compare SpaceX's current test-to-failure of Super Heavy and Starship to human-rated missions from anyone. They did the same test-to-failure rapid development with Falcon 9 and Cargo Dragon, leading to Crew Dragon, and they haven't had a life-lost incident yet. They're not deliberately testing-to-failure with humans on board.

Ok I need my #GenX people to tell me if I explained this wrong: talking to the younger folks who ask "well what was your generational trauma?"

My answer is the #Challenger disaster. We spent a whole year watching videos from #NASA about Christa McAuliffe and her space journey, and then watched her and 6 other people get vaporized on live TV, and... then never talked about it again?

They literally wheeled the TV back out of the room and moved on to Social Studies.

Day 22 cont 🗳️🖕🐧

“Traditionally safe seats are #flipping around the country, as voters put their hopes and dreams in independent and non-major party candidates.

But it takes more than just hopes and dreams to create a seismic political #shift that flies in the face of decades of voting history.

So what does it take for a #challenger to pose a real threat to a #SafeSeat?”

Idly reading about the #Challenger #SpaceShuttle explosion

....and I think I found a time traveler.

The previous several launch attempts were scrubbed for various reasons. The day before the launch:

"Monday was the next opportunity, but a screw failed to release from the crew hatch of the orbiter. A drill was ordered to be driven to the pad, but the battery was flat. ***Nine more batteries were sent to the pad, but all, for no apparent reason, became flat by the time they arrived at the launch pad.**" Time ran out and the launch attempt was scrubbed." [emphasis mine]

How does that happen? And how does someone, after changing a battery **4 times**, decide they need 5 more tried *using the same drill*?
