SpaceX’s Starship underwent a Rapid Unscheduled Disassembly—we do mean rapid

[smp]

From Ars Technica:
"On Friday, SpaceX prepared its latest iteration of the Starship prototype vehicle, known as Serial No. 4, or SN4, for a static fire test in Texas. The Raptor engine appeared to fire nominally for a couple of seconds at 1:47pm local time and then shut down as planned.

However, about one minute after engine shutdown there was some kind of uncontrolled gaseous leak, and one minute later the vehicle exploded almost instantaneously—a truly rapid Rapid Unscheduled Disassembly."

Isn't this the second time?

Isn't this the second time?

Maybe if you are counting different failure modes. There have been 4 catastrophic failures so far in one mode or another....
