CRS-7, the upper stage, had one of the bottles inside the tanks that are filled with helium.

And one of those bottles broke off on ascent and actually just completely overpressured the upper stage.

And the upper stage blew up and the whole rocket went kaboom in an uncontrolled manner.

And so then they came back with vengeance.

When they came back, the first mission back is the first time that they landed a rocket, which was awesome.
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
So they returned to flight after the anomaly was, yeah, was landing a rocket.
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
Just, I was surprised at how much bigger the rocket was than I imagined.

I was, I originally, when I was going down to Kennedy Space Center, I was disappointed that I wasn't seeing like a, you know, I didn't know a ton about rockets.
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
I knew enough to like know what a space shuttle was, what like the Saturn V was, you know, but that was probably about the end of my knowledge.

I just remember being disappointed that I wasn't seeing a big quote unquote NASA rocket flying.

#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
You know, I was thinking in my head like, oh, I'm going to see this launch.
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
It's probably going to be like...
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
you know, three stories tall or something, you know, just some little skinny little stick and some little firecracker and yay, you know, and I think I'd almost been pitched that too.
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
I think the, the people that I was working for at the time, I think they kind of were downplaying it as like, well, it's not a big rocket, sir.
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
It's not going to be that exciting, you know, but we get out there to the pad and I'm like, this thing's huge.
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
This is not a small rocket.
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
Like this is,
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
It's 70 meters tall, 220 feet tall.
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
It's huge.
Lex Fridman Podcast
#356 โ Tim Dodd: SpaceX, Starship, Rocket Engines, and Future of Space Travel
And I think people forget the scale of that.
