| Apr 27, 2023 at 2:10 | comment | added | Loren Pechtel | @JörgWMittag Look at the Challenger catastrophe. Watch the boosters after things go wrong--they receive and honor a destruct command. (Note that most of the video out there focuses on the main explosion and doesn't show this. You need to find one that shows the boosters.) | |

| Apr 26, 2023 at 14:45 | comment | added | Jörg W Mittag | The problem with such statements is that Starship is both the crew vehicle and (part of) the launch vehicle. Like the STS Orbiter, and that one did not have an FTS as far as I know. | |

| Apr 26, 2023 at 9:15 | comment | added | Mark | @KevinKostlan, a crippled rocket is also one that is breaking up because of a rapid spin, or one where the first stage is exploding from a fire in the engine section. The self-destruct is no more violent than this: it ruptures the fuel tanks, but since the fuel and oxidizer aren't mixed, the result is more of a rapid fire than a fuel-air explosion. | |
| Apr 26, 2023 at 8:21 | comment | added | Kevin Kostlan | A crippled rocket which is out of control or at risk of explosion or other malfunction most of the time gives the capsule some time to escape. But doesn't the self-destruct cause a fuel-oxidizer explosion "instantly"? If there is i.e. an electrical short that energizes the wires that detonate the perforation charges there will be no time to get out of the blast radius? | |
