The Titanic sank due to cheap rivits.

I have not studied the fires in Building 7. The Elevator shafts may have been designed to be part of the structural stength of the buildings, and the fires may have gotten into the elevator shafts, and unprotected steel beams.

Steel beams are covered with sprayed-on fibre insulation material that is designed to hold off the heat of a fire for 2 hours. Building 7 burned longer than 2 hours, and the sprinkler systems failed, which would have provided cooling.

The collapse of Towers 1 and 2 must have had some effect on the underpinning foundations of Building 7. The vibration of the collapse of the Towers may have had an effect of creating fissures and falling off of the fibrous insulation for the steel beams.

One change I have seen in buildings today, is that the stairwells are starting to be pressureized with fresh air, so that smoke filled stairwells will be less likely in fires, blocking people from exiting the building.

Is there a good description of the fires in Building 7 on one of your resources?

Flames are 2000 to 3000 degrees. Fires in houses are fought by chopping a hole in the roof, so the heat can escape, and water can be poured in the top. There was not much cooling for Building 7, and the heat may have just kept building up inside. I have not heard a good analysis of the sprinklers in Building 7. The pipes for water may have been broken by the damage by the Towers falling. Were there broken natural gas lines? What other flamable material was in Building 7? Even Fire retardent material at 1000 or 1500 degrees is going to oxidize, burn and give off more heat.

I am not saying the Bush, Cheney and Rumsfeld are above setting explosive charges. Foreign country military service explosive experts could have been used, so Congressional Inquiries are worthless.

If explosives were used, those who would know about it would keep their mouths shut. Even those who saw evidence of explosives in the rubble, would also keep quiet. It is too embarrassing. Bush is an embarrassment, as I remember someone pointed out to me before he was even elected,

What are the estimated temperatures inside Building 7, over time?

I believe I already watched your video subtitles in an earlier post. The video in the last post did not work for me.

Bending is a property of cold steel. Hot steel is more like soup. I took a metallurgy class in college, and hammer-forged some hot steel. Red hot steel is about 1000 to 1500 degrees, Whte hot is 1600 Degrees F. Hammer some hot steel and tell me what you think of its bending properties.
