Do you believe that AA 11 and UA 175 hit WTC 1 and WTC 2 on September 11, 2001?
Do you believe that AA 77 hit the Pentagon?
Do you believe that UA 93 hit dirt in Pennsylvania?

the building was designed to take a plane hit,
Yes, I know that it was based on impact from a 707.. A Jet that was half the weight of the 767... That's why the building took the initial impact but simply could not withstand the long-term weakening afterwards. And the Fact that the Jet that impacted the building was roughly 250% larger that what the building was designed to take, it kind of throws your conclusion on its head a bit using that magic numbers you plucked from the air.

wrong
read the link
The maximum takeoff weight for a Boeing 707-320B is 336,000 pounds.
The maximum takeoff weight for a Boeing 767-200ER is 395,000 pounds.
The wingspan of a Boeing 707 is 146 feet.
The wingspan of a Boeing 767 is 156 feet.
The length of a Boeing 707 is 153 feet.
The length of a Boeing 767 is 159 feet.
The Boeing 707 could carry 23,000 gallons of fuel.
The Boeing 767 could carry 23,980 gallons of fuel.
The cruise speed of a Boeing 707 is 607 mph = 890 ft/s.
The cruise speed of a Boeing 767 is 530 mph = 777 ft/s.

so what safety factor is standard for modern 50+ story bldgs?
I ask honestly

Possibly.
But heat steel enough and you compromise integrity which is exactly what happened.
You can't understand that because you choose not to.

and most structures, and pressure vessels are built with a minimum of 300% safety factor
so, at 50% reduction you are down to 250% SF
This is laughably stupid. Just realize you’re out of your element and STFU

you know the stuff we were discussing above
How did this collapse occur? Due to an overweight AC unit.
Third time
Why did it pancake just like the WTC?

no, the math does not line up
if I have a massive beam, the heat transfers thru it all in order to raise it's temp
1000° fire does not mean 1000° beam

He already told you.
It’s structural integrity decreased by 50%. From 300% to 250%

Sure it does.
What happens when steel connections lose integrity?

beliefs are useless as a screen door on a submarine when discussing facts
beliefs cloud your judgement, bias your ability to discern facts
is there a single thing that would change your mind?

(hint) math uses things like this a + b = c
so lay some math on me big boy

I believe you can heat still to the point that it changes structural integrity.
That belief is based on fact.

Change my mind on what?
Why can’t you answer the questions?
Once again, are you one of the “I know nothing and believe nothing and can’t answer anything because I’m just asking questions” people?
It’s been 21 years. If you haven’t developed your own personal opinion on the happened that day after two decades of studying the matter, then I don’t know why you’re even discussing it. If you don’t have a personal belief or even a theory by this point, you likely have some cognitive disability.
