Things that were indeed corrected that you once again ignored....
I want to give you a very clear example of your "corrections"
2) The towers were NOT built to withstand the 767's that hit them as you claimed. They were designed to withstand a 707, low on fuel, at lower speeds....
The towers were built to withstand the impact of a 707
ON TAKEOFF AND FULLY LOADED WITH FUEL BECAUSE THEY EXIST NEAR AIRPORTS
AND ..
The above graphic from Chapter 1 of FEMA's Report shows the sizes of a 707 and a 767 relative to the footprint of a WTC tower. 1 Flight 11 and Flight 175 were Boeing 767-200s. Although a 767-200 has a slightly wider body than a 707, the two models are very similar in overall size, weight and fuel capacity.
property ---------- Boeing 707-320 --------- Boeing 767-200
fuel capacity ------ 23,000 gallons ---------- 23,980 gallons
max takeoff ------- weight 328,060 lbs ------ 395,000 lbs
empty weight ----- 137,562 lbs ------------- 179,080 lbs
wingspan ---------- 145.75 ft --------------- 156.08 ft
wing area ---------- 3010 ft^2 -------------- 3050 ft^2
length ------------- 152.92 ft --------------- 159.17 ft
cruise speed ------- 607 mph ---------------- 530 mph
Given the differences in cruise speeds, a 707 in normal flight would actually have more kinetic energy than a 767, despite the slightly smaller size. Note the similar fuel capacities of both aircraft. The 767s used on September 11th were estimated to be carrying about 10,000 gallons of fuel each at the time of impact, only about 40% of the capacity of a 707.
John Skilling was the head structural engineer for the World Trade Center. In a 1993 interview, Skilling stated that the Towers were designed to withstand the impact and fires resulting from the collision of a large jetliner such as Boeing 707 or McDonald Douglas DC-8.
Our analysis indicated the biggest problem would be the fact that all the fuel (from the airplane) would dump into the building. There would be a horrendous fire. A lot of people would be killed, ...
The building structure would still be there.
A white paper released on February 3, 1964 states that the Towers could have withstood impacts of jetliners travelling 600 mph -- a speed greater than the impact speed of either jetliner used on 9/11/01.
"The buildings have been investigated and found to be safe in an assumed collision with a large jet airliner (Boeing 707—DC 8) traveling at 600 miles per hour. Analysis indicates that such collision would result in only local damage which could not cause collapse or substantial damage to the building and would not endanger the lives and safety of occupants not in the immediate area of impact." ..
ie; the Second Law of Thermodynamics .. which neither you or any other fairy-tale believer seem to know nothing about.
On Feburary 13, 1965, real estate baron Lawrence Wien called reporters to his office to charge that the design of the Twin Towers was structurally unsound. Many suspected that his allegation was motivated by a desire to derail the planned World Trade Center skyscrapers to protect the value of his extensive holdings, which included the Empire State Building. In response to the charge, Richard Roth, partner at Emery Roth & Sons, the architectural firm that was designing the Twin Towers, fired back with a three-page telegram containing the following details
THE STRUCTURAL ANALYSIS CARRIED OUT BY THE FIRM OF WORTHINGTON, SKILLING, HELLE & JACKSON IS THE MOST COMPLETE AND DETAILED OF ANY EVER MADE FOR ANY BUILDING STRUCTURE. THE PRELIMINARY CALCULATIONS ALONE COVER 1,200 PAGES AND INVOLVE OVER 100 DETAILED DRAWINGS.

4. BECAUSE OF ITS CONFIGURATION, WHICH IS ESSENTIALLY THAT OF A STEEL BEAM 209' DEEP, THE TOWERS ARE ACTUALLY FAR LESS DARING STRUCTURALLY THAN A CONVENTIONAL BUILDING SUCH AS THE EMPIRE STATE BUILDING WHERE THE SPINE OR BRACED AREA OF THE BUILDING IS FAR SMALLER IN RELATION TO ITS HEIGHT.
...
5.
THE BUILDING AS DESIGNED IS SIXTEEN TIMES STIFFER THAN A CONVENTIONAL STRUCTURE. THE DESIGN CONCEPT IS SO SOUND THAT THE STRUCTURAL ENGINEER HAS BEEN ABLE TO BE ULTRA-CONSERVATIVE IN HIS DESIGN WITHOUT ADVERSELY AFFECTING THE ECONOMICS OF THE STRUCTURE.
Frank A. Demartini, on-site construction manager for the World Trade Center, spoke of the resilience of the towers in an interview recorded on January 25, 2001.
The building was designed to have a
fully loaded 707 crash into it. That was the largest plane at the time.
I believe that the building probably could sustain multiple impacts of jetliners because this structure is like the mosquito netting on your screen door -- this intense grid -- and the jet plane is just a pencil puncturing that screen netting. It really does nothing to the screen netting.

So much for your stupid ass unlearned, unresearched "correction."
You don't know what the fuck you're talking about, you don't know science, you don't know structural engineering .. including Damo's friend, and most importantly, you don't know what the fuck you're talking about.
NONE OF YOU DO.
You're babies finding it hard to accept there is no Santa Claus.
