    Watching the last 5 minutes of countdown, I wish them luck but compared to SpaceX, they have at least 2-3x as many parts that must work together:
    • solid rocket strap on
    • multi-engine second stage
    • strange mounting between second stage and Starliner
    • auxiliary needed to achieve orbit after second stage shutdown
    GOOD LUCK!

    Gosh, they sure like to delay jettison of solid rocket engines, 48 seconds, and nearly two minutes for delayed capsule and second stage separation. The extra mass does nothing to improve orbital insertion. Regardless, well done.

    I just got word from a friend who lives a little closer that I do. He said it was fun to watch from his house.

    So close now to finally not having to make our astronauts hitch hike into space. (y)

    Apparently something was amiss.

    To carry the empty solid fuel rocket shells 48 seconds of powered flight was wrong ... unless releasing would have overstressed the upper stage and stack. As for the Centar second stage, it sure was lethargic.

    Boeing and ULA has a problem.

    Too bad.

    I used to say “If it ain’t Boeing, I ain’t going.....” but they seem to be having a pretty tough run of bad luck lately.
    They’re supposed to land “within the next 48 hours”
    I hope they get the vehicle back more nominally.

    Good Luck Guys!

    They are still clarifying the problem but an event clock seems to have gone awry. Starliner itself will land ever so gently at White Sands.

    Gently @ White Sands: hopefully!

    Those guys are due for some good luck.

    Man!
    That landing looked like a Rube-Goldberg affair.....but they got it down.

    Perhaps if you gave them more (government) money they could have done better.
    They try that logic for education, why not for space development? Throw more taxpayers' money at it! :(

    Elon is way ahead in the paradigm shift. Boeing is tied to yesterday's culture and convention. They are creatures of the old habit.

    The Atlas 5 is old technology and is thrown away with a one time use.

    Geoffrey De Haviland gambled ad lost with the Comet. Boeing used De Haviland's lessons learned with the 707.

    Elon gambled with the newer technology and apparently won.

    Bit of a different thing.

    The de Havilland Comet was the world's first commercial jet....and it's direct descendant (The MR.2/MRA.4 Nimrod) was only recently retired.
    Space capsules are hardly emerging technology, and they've been around for well over a half a century - although Musk certainly is revolutionizing the delivery vehicle.
    Space-X seems to be satisfied using old tech when and where it's able to, and the Dragon reminds me of a re-warmed Soyuz capsule that's capable of an Apollo-style recovery mode.

    In the Military, we call that KISS.

    As far as the money thing, Boeing has to pass critical design tests on a pre-defined budget.
    Otherwise?
    NASA will give their bucks to SpaceX....a privately held company.

    THAT
    is as different as how we fund our education system in America as Boeing's 787 Dreamliner is from the first 707s (also....still in service!)


    Fun Fact:

    You just HAVE to love the Brits.
    When they deploy lumbering, multi-engine military surveillance and reconnaissance jets that were developed from commercial airliners....they put a couple of AIM-9 Sidewinder missiles on them......you know......"just because."

    The Atlas is still using the "balloon" pressurized stainless steel tanks that Convair used on the MX774.

    Elon uses lithium aluminum alloys like Weldlite.

    The balloon tank means that the Atlas is expendable and never be returned to earth like the Falcon rocket for reuse. It needs the pressurized fuel to support it at atmospheric pressure of sea level. As it expends it's fuel, the pressure is lower at altitude both on the outside on the inside. Less support is needed. When the Atlas returns to pressure at the surface, it collapses like a limp toothpaste tube.

    Perhaps the US Gen 2 Prius gas tank was meant for only one-time use?? o_O:oops:

    Speculations about the 48 seconds to carry the empty solid fuel rocket cases:
    • so it won't fall on any people in the Atlantic ocean
    • because they could tumble back into the booster like the failed Soyuz launch
    We've declared areas of the Atlantic a hazard area for decades. They couldn't predict an area to block off for the solid rocket booster landing?

    Soyuz has been discarding strap-on boosters for decades and an equipment failure led to the Russian one. Yet in spite of hundreds of strap-on booster discards they can master how to release solid rocket boosters to peal away?

    Next you'll tell me they can't set a VCR or microwave clock either.

    What bothers me most, SpaceX is not allowed to use rocket power to do a dry landing. Personally, I think all Dragon capsule landing without a crew should be done on either a drone ship or at Kennedy.
