Dan & Joey,

    We do not have enough information yet.

    Joey is on the 6M list and many of the guys prayed
and encouraged him through the early days following his

    Joey didn't post the insurance report, perhaps the
missing variables are in there.

    I am guessing that the tower may have suffered some
sort of internal rusting or some other damage prior to
his work on it.

    The stress of the work at 100 feet and then removing
the top sections may have stressed those weaknesses until
they finally gave.

    There may also have been a change in weather, e.g.
wind gusts, temperature, etc.

    Metal fatigue sometimes results in failures at odd
moments and I am sure Joey is happy that tower failed
when he was at 40 feet vs 100!
