This is an experiment you can try in your own home. Get a candle, a screwdriver, Craftsman from Sears preferably, any size, oven mitts and a match.
Light the candle and place the metal from the screwdriver into the flame. Hold it there for two hours.... What you have done is recreate the fires that we are told brought down the twin towers.
Oh, you can put the screw driver back into the drawer, let it cool for a minute or two. No, it didn’t melt or twist or buckle. It may not even have discolored. It certainly didn’t light up like a sparkler on the 4th of July.
Sometimes engineers aren’t the brightest people in the world. Education and common sense are often at odds....
If you held a huge blowtorch to the twin towers, the heat would have flowed down the struture (sic), quite evenly I suspect, and radiated across lower Manhattan.
We don't need no steenkin' engineers!
