@neptuneblue,
Is Leslie Robertson a liar? Do you even understand the significance of molten and vaporized WTCs 1, 2 & 7 structural steel? Muslim "hijackers" brought fires that were MAXIMUM 1500F and steel melts at 2800F, vaporizes at 5,000F unless thermate/nanothermate is used.
Leslie Robertson, a member of the engineering firm that designed the World Trade Center, said 21 days after the attack: “When we were down at the B1 level, one of the firefighters said, ‘I think you’d be interested in this,’ and they pulled up a big block of concrete and there was a, like a little river of steel, flowing.”
