@JTT,
Let me ask you a question JTT.
Do you think heat travels in steel that is heated?
If you heat one end of a steel rod does the other end get hot?
Put part of a metal truss in a 1300 degree furnace. How long will it take for a part not in that furnace to get to 250 degrees? That is the test. You have already argued that the trusses couldn't have failed because the heat travels across them so fast that it can't get hot enough to cause failure. That is in direct contradiction to your claim that the truss would pass an e119 test without any fireproofing.
