What was the cause of the two twin towers to collapse?
The collapse of the Twin Towers on September 11, 2001, was caused by the impact of two hijacked planes (American Airlines Flight 11 and United Airlines Flight 175) crashing into the buildings, which weakened the structures, combined with the intense heat from the resulting fires that caused the steel framework to lose its structural integrity.
What forces were acting upon the twin towers?
The forces acting upon the twin towers were primarily gravity, wind loads, and the impact of the airplanes on 9/11. These forces caused structural damage and ultimately led to the collapse of the towers.
Did the twin towers collapse quickly because of explosives?
No, it was actually the heat from the fires that weakened the steel in the structures. The resulting "pancake" collapse was a result of the same thing that happens when you knock over a row of dominoes - the failure of the floor where the planes hit (due to the above weakened steel supports) caused it to fall directly down on the floor below, which could not withstand such an impact, and it failed, hitting the floor below, etc.
How did the twin towers got destroyed?
The Twin Towers were destroyed in a terrorist attack on September 11, 2001. Two hijacked airplanes were intentionally flown into the buildings, causing them to collapse. The attacks resulted in the deaths of nearly 3,000 people.
How did the Twin Towers fall down?

How many people die in the twin tower incident?

Why did the tower next to the twin towers fall when it had nothing to do with it?
The "official" story was that building 7 fell due to damage from falling debris from the twin towers. Amazingly this 3rd building fell straight down into itself just as the twin towers did. 3 buildings damaged at different points and damaged for different periods of time all fell the EXACT same way. You be the judge and see if this is actually what happened!

Is there a height of impact that would have caused the twin towers to collapse immediately?
The bottom floor, most likely, and some floors just above it. Up to about halfway, there was a decent chance of it happening.
Did the exploson have an affect on the twin towers?
The explosions caused by airplanes impacting the World Trade Center towers first caused huge holes in the respective north and south faces of 1 WTC and 2 WTC. The fire started by the explosions, combined with the damage to floor beams and inner support structures, weakened the towers to the point of collapse.
Do people miss the twin towers?
it use to but on September 11, 2001 two planes crash into both towers. the by 10:05 south tower collapse. then by 10:28 the north tower collapse. so now the do not exist.
