    BBC had video clip of a worker presumably weakening a tall smoke stack. Looks somewhat dangerous. See,

    Why weaken it? Why not just use explosives?

    Ease of cleanup (as it falls in a nice line, instead of a giant pile) and predictability in how it will fall (so it doesn't crush nearby buildings/walls/etc. Plus it's cheaper than designing and executing a controlled explosion.

    People have been cutting down big trees that that was for thousands of years. It's only dangerous if you do it wrong ....
