  • what is the advantage of the oxy torch to for instance an angle grinder ? just wondering...

  • So we can see how much work was necessary to cut through just a 20 inch thick concrete wall.

    Imagine if you had picked up a piece of concrete the same size as that door, and dropped it 3.7m onto the ground. Would it have turned into dust? Of course not.

    But on 9/11, almost ALL of the concrete in WTC 1 and 2 was turned into dust, in MID AIR, while each floor hit the floor below it... Where did the energy come from? The floors were 3.7m apart.

  • how does those microblasters work? explosives?

  • Ive walked through that vault befor they put the hole in it.

  • How does this work when the concrete is reinforced? the reinforcement in this wall was almost non-existing...
