And pretty major pieces that get replaced with nothing breaking noticeably.

A better analogy would be like swapping the engines for electric drive props mid-flight, while other team is replacing most of the wings, but keeping the control surfaces in place.

Now, the cargo service would've been killed, and you'd have 3 mostly equivalent screens to choose from to watch movies during your flight.

And SpaceX did blow up a spaceship for human flight where they didn’t expect it to.

The teams they buy could!
