    > Booster Systems Engineer Jenny M. Howard acted quickly to recommend that the crew inhibit any further automatic RS-25 shutdowns based on readings from the remaining sensors,[6] preventing the potential shutdown of a second engine and a possible abort mode that may have resulted in the loss of crew and vehicle (LOCV)

    Incredible that human action during ascent (when everything is usually automated) potentially saved a crew. One of probably dozens of cases, is my guess.

    STS still has the record for most astronauts killed. I don't believe we will surpass that grim record until Starship starts carrying humans.

      By the time Starship carries humans (assuming that it will, which I do), it will likely have flown uncrewed more times than Shuttle + all prior American programs together.

      They know it’s going to be tricky to make landings safe for crew. Nobody’s in a rush to fly people.

        Agreed! But just as airliners eventually had a disaster, Starship will eventually have one too. Maybe it will be earlier and kill only single-digit number of astronauts. Or maybe it will be later, when it is transporting 100 people at a time.

        The only way Starship won't kill people is if it's phased out earlier than expected (earlier than I expect, anyway).

        And, of course, I very much hope I'm wrong and no one ever dies on a rocket again.

          The Embraer ERJ family is currently at 0 deaths over the whole lifetime if you exclude the Wagner crash, which probably wasn’t really a fault of the airplane.
