    Tom, you seem to be making an implicit assumption that CNN played the
    Mir reentry video at the same speed that it was recorded. I would
    guess that CNN played it fast, probably at about 6X. That would be
    consistent with verbal eye witness reports, which said it was about a
    minute and a half.
    Is there anybody out there have inside knowledge of what goes on at
    CNN that can tell us at what speed CNN played it?
