Jeff King knows what he's talking about. A must see.

So an MIT prof has seen fit to offer his opinion...
a 60 year old former electrical engineer and more recently a Family Practice physician. I graduated from MIT with an SB degree in 1974, with a combined Biology-EE major (this was before a Bio-Medical Engineering Department existed), and before settling down to do clinical medicine I worked for about eight years in electronics and electro-mechanical engineering. For the past 27 years I have been working full time as a family physician, doing office-based primary care here in the rural San Joaquin Valley of central California.
Since 9-11 I have also been deeply involved with collecting, analyzing and making available to the public and other researchers as much as I could find of the photo and video evidence of the World Trade Center collapses.

Jeff King watched the collapse for the first time and determined it was a CD? WOW Why didn't NIST call him. Would have saved us all millions.
The guy is using the "squibs" argument. Yeah I will totaly listen to him.
Same old truther rhetoric without any facts to back it up.
Typical

That would be pretty amazing for a dead engineer to say, no?
Skilling was the main structural engineer over Leslie Robinson. He died in 1998 I believe.

However, ole Leslie's opinion is that the collapse was a result of the damage and fire.
"Leslie E. Robertson, the lead structural engineer on the team that designed the towers, wrote that "The events of September 11 are not well understood by me . . . and perhaps cannot really be understood by anyone." As NIST would also conclude"
During a 1984-85 Office of Special Planning study into the vulnerability of the WTC to a terrorist attack, Leslie Robertson, one of the two original structural engineers for the World Trade Center, assured investigators that whether the towers suffered a bomb attack or were hit by an airplane, there was "little likelihood of a collapse no matter how the building was attacked."
In 2001, Leslie Robertson again stated, "The twin towers were in fact the first structures outside the military and nuclear industries designed to resist the impact of a jet airplane."
"As investigators have pointed out, immediately after 9/11 Leslie Robertson refused to discuss the collapse of the buildings with the media but he later recanted and agreed with NIST's conclusions"
Immediately after 9/11 it was reported that “the engineer who said after the 1993 bombing that the towers could withstand a Boeing 707, Leslie Robertson, was not available for comment yesterday, a partner at his Manhattan firm said. ‘We're going to hold off on speaking to the media,’ said the partner, Rick Zottola, at Leslie E. Robertson Associates. ‘We'd like to reserve our first comments to our national security systems, F.B.I. and so on.’” arabesque911.blogspot.com...
Mr. Robertson has said some very interesting things worth inquiring about.
"I designed it for a 707 to smash into it," he told a conference in Frankfurt Germany.

Do you have a source for this? Not that I'm disputing you, but I have been hard pressed to find Mr. Robinson's comments on the WTC collapses. Maybe I'm looking in the wrong place?
So far, this is the only thing I can find of Mr. Robinson saying anything about it. BTW, I don't see where he states that the plane damage and fire was the cause of the collapse. Actually, I don't see where he has said anything about the collapse itself other than what is mentioned here. Please let me know if/when you find the actual quotes from him. Thanks.

Edit: Could be because I'm spelling his name Robinson when it's Robertson.
Edit again: I still haven't found a direct quote from Mr. Robertson.

"In retrospect, I would have made them sturdier. But making them sturdier doesn't mean that they would have stood up because the failure was the result of removal of the structure by the plane and degradation by the fires."

"I know more about the project and more than anyone ever will about the design. There's no one alive today who's even close to what's stored away in my head and I've got a memory like a sieve. It's true that, following the event, a lot of people - architects and engineers - stepped up to the interview platform and had their say and, by and large, most of them spoke much too quickly and without a lot of knowledge. There's a need to understand what should be said before saying things."
Robertson counsels that there are no absolutes in his discipline, that we are not talking about a fine Swiss watch, that imperfect materials are employed to construct imperfect buildings, that each structure has its strengths and weaknesses.

Yes it does. Thanks.
It still doesn't refute his and Skillings' calculations and comments prior.
And please don't bring up the titanic as your next argument. Thanks. I've already debunked that faleshood. The engineers never said the titanic was invincible. It was a newspaper ad. And we know how reporters are when it comes to facts, right?

No, he doesnt come out and refute the calculations, but he does say that a fully fueled 767 traveling at high speed WASNT considered in those calculations and that the kinetic energy would be several orders of magnitude higher.

Actually, I was under the same impression as bsbray. That the exterior columns were the same size the whole way up. The difference in strength comes from the use of higher strength steels at the base.

In contrast to the upper stories, in the lower stories, the perimeter column flanges were as thick as 3 in. (76 mm) and typically made of lower strength steels.
No further information is given on the transition points in the columns from one thickness to another and one grade of steel to another.
