    Correct. To recap somewhat, 8:53am EST is the time the Shuttle was making
    its landfall over the California coast. At pretty much the same time, the
    temperature readings of the starboard wing inboard and outboard elevons
    were lost, the first sensors to fail (followed by other left wing sensors
    in the following minutes). Considering that we seem to have, by now, pretty
    certain visual reports from California observers that the Shuttle
    apparently was trailed by very small debris, IMO it doesn't take much
    rocket science to imagine what happened there. Whatever the exact root
    cause was (I'm avoiding the ET insulation foam issue here), to me this
    sounds like the starboard wing was disintegrating since fairly early in the
    entry interface.
    Anyone agree (or disagree)?
    CU!	Markus
