    Push a button, get a banana. Crew have become almost tertiary. Space exploration has demonstrated this far more than aviation. Personally I think Cargo Dragon autonomously docking with the ISS was a bigger deal. Sorry I just can’t get that excited over a guy manually firing a reaction jet. BUT.... I am very glad that we are no longer dependent on the Russians. We should have never walked away.

    Must have my Space Curmudgeon hat (helmet?) on today.

    Having the ability to manually fire a thruster has saved NASA crews in the past (Gemini VIII, Apollo 13). The question is HOW the crew can fire the thrusters...whether the manual input goes into the same computer that's bollixed things up already. If the manual control requires 98% of the same circuitry and software that the automated circuit uses, then it's not really providing a "manual backup."

    Still, it is just "fly by wire," which has become common enough in aircraft.

    (Obligatory space story: We had a thruster control system fail on the Air Force Early-Warning satellite I used to operate as a young officer. A software engineer named Lieutenant Knight quickly developed a fly-by-wire-like system that used ground computers to switch modes to operate the thrusters. This software patch was officially dubbed, "Fly By Knight.")

    Well...what would have been the downside if we'd stopped sending crews into space? The fact is, other than national pride, there isn't much use for humankind in space. It's good that human space travel is now being provided by a private vendor, but the US Government is still into it deep, financially.

    It's the right way to go, and I support human use of space. But dollars-and-cents-wise, it doesn't make sense. It's not something we HAVE to had, and with the economy tanking, it may well be an early casualty.

    Don t know if anyone knows about it, but on Space X and NASA site there is a simulator that lets you try to dock with ISS. I crashed a few times.

    I was blown away by the all glass panels and the room inside the Dragon!
