Starliner successfully docked to a space station to deliver crew, a feat first achieved in 1971.

Starship flew into space and crashed, a feat first achieved in 1944.

Nobody broke any big milestones, both were just test flights, that are both horribly behind their promised time-frames.

I think that’s a reductive take of what starship just accomplished today but you’re certainly entitled to your opinion.

It’s okay to hate SpaceX as much as you like but what gave you the impression that starship crashed? Both the booster and the ship itself softly touched down on the water at less than walking speed. They would have been fine on land and the only reason why they did it over water is that nobody had ever successfully landed something that big until today. Nobody had even reentered the atmosphere with something that big. The biggest so far was the Space Shuttle orbiter. The starship upper stage is 1.5 times the size and more than twice the mass of that.

Starship demonstrated a recoverable heavy-lift booster, aerodynamic reentry control, high-bandwidth reentry communications, and a successful test of flight software despite hardware failures, all while launching an incredibly heavy thing into space.

For comparison, the Starship can carry two dozen fully fueled V-2s into space.

A bit pedantic, but unless I'm misinterpreting the Wikipedia page for the V2, I think it's only 4 to 6 fully fueled V-2s based on the listed payload capacity of 100-150 tons US.

V-2 dry: 27,600 lb
Warhead: 2,200 lb
Propellant: 8,400 lb 75% ethanol / 25% water, 10,820 lb liquid oxygen

Total weight: ~24.5 tons US

I appreciate your pedantry. I was just going off a quick google for "weight of V-2 fully loaded" and "mass of Starship to orbit" because it's been quite a busy day here.

You're technically correct, and that's the best kind. πŸŽ–οΈ
