He that's racist....USA knows how to make cheap steel too! Stop excluding us.

the demo guys previously had probably only blown up cheap chinese steel. this was old US steel

This was probably all shaped cutting charges... The problem with that is the internals of the steel. They usually pre-cut some of the members to determine the composition of the charges and if they cut the wrong member they get the wrong results...

Pretty sure they didn't think the steel was going to be that resilient.
Its a far away shot, but it doesn't look like there's anything but
superficial damage.

     I have just enough nautical knowledge to seem stupid on the
Internet... My theory is that they were planning to neatly cut it into medium sized chunks that could be reasonably lifted out of the river with a medium sized crane on a flat barge and carried away. Severing the whole thing and dropping it into the river in one piece
    would require a significantly larger/more expensive crane and
    corresponding barge.

Not enough explosives at the severing points, or an underestimate of
    the strength/grade of the steel?

OK, mechanical stuff is not my strong point. But for anyone who watched the video of the failed bridge implosion in Little Rock,
        Arkansas, what were they thinking?  It seems they rigged
explosives on the arch and the bridge deck, both of which are in compression. It seems to me they needed to sever the cables, which are in tension. That at least would have caused the deck
        to collapse.____

If you only see yourself as part of the team but you don't see your team as part of yourself you have already failed as part of the team.
