And we already know that it not physically possible for jet fuel to melt thousands of tons of steel that's has a specific heat capacity of 700-1000 degrees more.

No it doesn't.
the maximum temperature that jet fuel burns is more or less 1,000 C.
No it isn't.
It is known that structural steel begins to soften around 425�C and loses about half of it strength at 650�C. However, even with its strength halved, the steel would still be able to support two to three times the stress imposed by a 650�C fire. There were also distortions of the steel due to higher temperatures in some areas than others. Because of these aspects, the failure of the steel was ultimately due to two factors: the loss of strength due to the temperature of the fire, and the loss of structural integrity due to distortion of the steel from the non-uniform temperatures in the fire [3].

Can you imagine that it can be set-up after closing hours? As in during the night?

Ehhhh, try again please. According to news reports of the time as well as interviews with the engineer and architects, Nova did a great show on it, they took into account the biggest fastest commercial plane of the time. A Boeing 707. The 747 was not considered a factor at that time.
The point has already been covered by Howard. I did not think it was worth addressing this moot point. The towers were built to withstand a 707 at 600mph.
There engineers on public record that also say they the towers could have survived a 747. A boeing 707 and a 767(the impact airliners) are only slightly different. The 767 is a little heavier, while the 707 is faster.
The maximum takeoff weight for a Boeing 707 is 336,000 pounds.
The maximum takeoff weight for a Boeing 767 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.
Here is the physics
The Kinetic energy(1/2mv^2) of a 707 at 600 mph is 5,607,720 Kilojoules
The Kinetic energy(1/2mv^2) of the 767's that struck the towers are:
AA Flight 11 at 470 mph is 3,950,950 Kilojoules
UA Flight 175 at 590 mph is 6,227,270 Kilojoules
Therefore AA flight 11 had 30% less energy than the towers were built to withstand. And UA Flight 175 was only within 10% more.
So we can rule out that it was the actual impact and stress that caused the towers to fall. The collapse is attributed to the melting of steel and not the stress caused by the impact.
And we already know that it not physically possible for jet fuel to melt thousands of tons of steel that's has a specific heat capacity of 700-1000 degrees more.
. . .
I am getting sick of your patronizing attitude. I saw one source quote the specific heat capacity of jet fuel as 220 to 550 degrees, either way it is way below the actual melting point of steel. If you think your physics checks out, and I personally believe it a load of rubbish, go for the $100,000 and put your mouth where the money is(pun intended)

New World Order day, sort of.
Any google search will tell you this. bah

Actually, for being a person with 3 fluent languages i consider myself extremely smart and wise, maybe the grammer isnt up to par, but then again nevertheless the intelligence is there, brother.... Nothing gullible about me..in fact, its because i'm not gullible that i refuse to swallow the crap. Get the point?

DG....you should be the last person telling others in here about their intelligence....you are too gullible sister.... By the stories and conspiracies I have seen you post, you would believe almost anything DG....and as always you don't seem to need facts for some reason....

building like the WTC never closes. There are always guards in the lobby, people patrolling the floors, workmen fixing/cleaning etc. It is impossible for a crew to sneak in after the building is closed.
Closing hours in NYC, in a building that housed businesses that traded in markets worldwide. That's rich. You have made my day.

Its ok, think whatever you wish.
And a Merry Christmas to you too.
