Actually, had it been winder that day it might have gone right. There were 8 joints. Only one failed, and only in one place. The spot being supercooled by boiloff from the LOX tank. And the leak self-sealed (there's aluminum in the fuel--hot exhaust touching cold metal deposited some of it) when it happened--but the seal wasn't robust enough and eventually shook itself apart.
