    Highly unlikely for anything to have survived much beyond 2:52 UTC; certainly
    not to 6:31 UTC. Even if it did, there are at least these problems:
    1. The image shows an object somewhat east of the setting moon, therefore, low
    in approximately the SSW. If a piece somehow survived, and arrived 30 min late,
    then its track would have been low in the SSW, but as you point out, it was
    running early at 2:52 UTC, by some 6 to 7 min, I estimate, so there is no way.
    2. I cannot discern the horizon, but assuming it roughly parallels the bottom of
    the image, then the path of the decay also should have paralleled the bottom.
    However, the object in the image descended at a considerable angle to the
    You can safely rule out the decay.
