There is structural engineering, mechanical engineering, electrical engineering, chemical engineering, telecommunication engineering etc, etc. Of which sub-discipline do you work in?Engineering is a field.

An engineer in what field?
BA in mathematics from UCSD, graduate work at UTD. I teach mathematics at a Christian high school.Electrical engineering, specializing in power electronics design, wireless power transfer systems, embedded systems design and smart grid systems design. BS from MIT, graduate work at UCSD.
How about you?
I just now heard Professor Dr. Niels Harrit say that no steel-framed high-rise has ever collapsed due to fire and that there have been super-fires in over 300 steel-framed high-rises and that none of their steel structures were affected by their super-fires. This audacious claim requires a credible refutation and a straightforward counterexample.You should really stop parroting what you read on Gage's site. Lots of steel framed buildings collapse due to fire.
Like the roof of this building:

No.Is that a Seventh Day Adventist high school in Richardson, TX?

That's not what the final NIST report is saying. I suggest that you get your vision checked or perhaps sign up for a reading course. But don't ignore the relatively minor fire in WTC 7.OK, so we have now established that flying a fully fueled 767 at full throttle into a tall building can cause the building to collapse.

How do you know that explosives weren't used? I'll tell you how you know. "Condemnation without investigation is the height of ignorance." --Albert Einstein. That and the fact that NIST didn't think it proper to interview scores of firemen and first-responders on the scene that have already testified to hearing explosions throughout the Twin Towers and WTC7 on 9/11.How can you call the fire minor it was large enough to cause the collapse of the building
You're certain that a building with a tin roof qualifies as a modern building but perhaps professional architects mean a structure with a modern (meaning sophisticated) level of modern design safety.You said "No modern steel-framed building has ever collapsed due to fire." You were wrong; we provided examples.

You are obsessed and will never change your mind, so why am I wasting my time?
Your imagination and fantasy expertise doesn't trump eyewitness testimony of unusual power-downs at the WTC up to the last weekend before 9/11.I am not going to spend the time to point out how it would be impossible to hide the loading of exposives for a demolition from the people in the buildings.
Doesn't mean a thing, there were no visible shock waves, that pretty much proves there was no deliberate demolition by explosives. You can't hide something like that, shock waves are what does the damage.Your imagination and fantasy expertise doesn't trump eyewitness testimony of unusual power-downs at the WTC up to the last weekend before 9/11. .
You must think that you were in charge of security for the WTC. Isn't that just a little insane?I am not going to spend the time to point out how it would be impossible to hide the loading of exposives for a demolition from the people in the buildings.
