I've seen the pictures, the main structure strutt weight maybe 50 ton but the beam (we call them beams in england, americans all them gurders)that fell 3 ft when it slipped hitting the main strutt and scaring the sh*t out of everyone could only of weighed 500kg at most . dropping 1/2 ton from 3ft onto the main strutt is like hitting a bell with a small hammer its just jerno bullsh*t mixxed with this countries obsession with health and saftey
