Fire burnt the steel the steel failed, the overpass collapsed same as the steel in the World Trade Center.
Why are you scared to reply with your engineering knowledge?
Was it hard and difficult for your to just say, "The tanker that exploded and caused San Francisco-Oakland Bay Bridge collapse on April 30, 2007"???
The steel supporting ramp several feet above the exploded tanker has weaken from the heat and collapsed. What this has got to do with the 1,370 feet one piece steel structure of WTC towers? Has any one claimed that steel bridges never collapsed before from heat???
The crap is what you are repeating without paying attention to what I say. "Jet fuel/ kerosene fire is not sufficient to melt or even weaken the thick steel structure of WTC".. Not sufficient to melt the 1,370 feet one piece structural steel of the World Trade Center, not the few feet of steel bridge>
Waiting for your next never ending crap.
