9/11 Revisited

I believe this is correct. The architect for the WTC towers was named in September 1962. The Boeing 707-120 debuted in 1958, peaked in popularity in 1960. The Boeing 707-320 came out in June 1962. It's unlikely that the towers were designed with the 707-320 in mind.

The maximum takeoff weight for a Boeing 707-120 is 257,000 pounds.
The maximum takeoff weight for a Boeing 767 is 395,000 pounds.

That's quite a difference.

 

The Empire State Building was designed in the late 1920's. The WTC towers were designed in 1963. Do you really believe that buildings taller than the ESB were designed35 years later were built to lower design requirements? That building codes became less restrictive in 35 years in Manhattan? No way. I'm not even going to bother checking that out.

 

I honestly can not decipher what you wrote.

 

Typo. I meant the Boeing 707-220ER.
707-220
The 707-220 was designed for hot and high operations with more powerful 15,800 lb (70.3 kN) Pratt & Whitney JT4A-3 turbojets. Five of these were produced, but only four were ultimately delivered, with one being lost during a test flight. All were for Braniff International Airways and carried the model number 707-227; the first entered service in December 1959.

The WTC Design was completed in Jan, 1964. It assumed the largest and heaviest aircraft then flying. That was the Boeing 707-220ER.

 

Constructed differently. The old buildings were stiffer and structurally harder. The newer buildings are designed to flex and move. Lighter weight can be stronger in many ways but weaker in others.

 

For complete disclosure, I am a member of Architects and Engineers for 9/11 Truth. It was an honor to be accepted into that group. There are only about 2,500 members and they did a thorough check of education and experience before they admitted anyone.

 

How do you know the WTC design assumed the 707-220ER was the plane used in their simulated crashes? Boeing only built five of these models, so I highly doubt you are correct.

The link you provided earlier only says this:
A three-page white paper, dated February 3, 1964, described its findings: “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.

 

Thanks for disclosing your membership in the tin foil hat society. That is not an easy thing to admit.

 

That seems logical. How fast could a 707 safely fly at above ground level of 1,500 feet?

 

Now, now Squire Robertson, the conspiracists can claim that "no pilot could make a plane fly that way" despite the fact that eyewitnesses saw the plane fly that way. But you, no, you are not allowed to suggest that only a certain handful of people would have the know-how to blow up the World Trade Center in a controlled demolition. Surely that's not specialized knowledge...</sarcasm off>
