    More failures than usual with Russian space program lately.

    Still not a bad track record for manned launches... last issue with a manned launch was in 1975 when a Soyuz 18-1 was on its way to Saljut 4. And then the astronauts also survived (one with severe injuries though).

    It appears a pyro failed, causing an incomplete booster separation (unit D). It flopped and impacted the core stage, rupturing a tank.

    At this point the launch escape tower had already been jettisoned to lighten the stack, but the Soyuz spacecraft has additional separation solid rockets on the spacecraft fairing and they worked. Good thing the fairing hadn't been jettisoned.

    The ballistic re-entry was pretty rough, almost 7G, but all looks good and they survived.

    Soyuz could return to flight much quicker than anticipated, possibly this year.

    BTW: both US Commercial Crew vehicles have their abort engines incorporated into the spacecaft, so abort is available from the pad all the way up to orbit. No fairing, no tower, or their separation events.

    It was very, very close. Those diapers they wear for spaceflight were both brown and full at touchdown. Those Explosive Bolts/Separation charges are supposed to be Triple Redundant, so I would expect to find that pyro didn't perform to nominal spec or was late detonating (both suppositions but a lot of people are speculating this).
