Problem with fire theory – Lack of fire

NIST says the main cause of the collapses of WTC1, 2 and 7 was high-temperature fires. However, these towers do not appear to have raging fires in them before they suddenly collapsed. WTC1 fell within 1 hour of being hit by a plane. Fires in WTC1 were in two floors at the time of the collapse. No flames shoot out of the windows.

Two towers – one on raging fire, the other one only minimal fire

The North Tower falls at 0:27 in this video.

Area of building on fire before it fell was small 

north tower 22 seconds before collapse.jpg

A still from the video above: North Tower 22 seconds before it fell. Only a small area of the building is on fire. Most of the building was not on fire. This picture shows the north-east face of the tower, the face that the plane hit. The outline of the hole made by the plane strike can be seen a little further up from the fire. Flames are barely visible and are only on a couple of floors. The initial fire that flared up when the plane made its impact seems to have mostly died out by this time in the video was reached.

Extent of fire in North Tower at 10:28am, time of fall

The North Tower fell at 10:28am. Diagram from NIST shows the extent of the fire at 10:28am, the time of the tower’s collapse. Fires are present on two floors: the 92nd and 98th floors.

There is very little fire in WTC2 on the right before it collapses. On the other hand, there is obviously a lot of fire in the Windsor Tower before it starts collapsing. Only the top six floors of Windsor Tower collapsed, and mainly the masonry. The steel skeleton of the building was still intact at the end, including the top six floors, when the fire had burned out, almost 24 hours later.

By 3am, 4 hours after the fire starts, the top six floors are completely gutted and start collapsing.

North Tower on the right only had small fires that were barely visible through the windows, on the 92nd and 98th floor before it suddenly collapsed. The picture on the right shows the extent of the fire before it fell. On the left is a tower in Dubai on fire. GIF taken from comparison video below. The North Tower fell less than an hour after the plane hit it.

Squibs

Smoke plumes are clearly seen shooting out from the right side of the North Tower right before the building starts to disintegrate and fall. These were probably smoke plumes of squibs being detonated.

Flames of a fireball while it starts to collapse

These flames were not present before it collapsed. Only small fires were present on the 92nd and 98th floors, seem as a thin line of flame, that were only visible through the windows. The flames in the GIF are large flames from a fireball.

Squib puffs shoot out from the facing wall

raging-fire-windsor-and-nor.gif

The two buildings’ fires appear very different. On the left, in Windsor Tower, the fire is obviously raging fiercely, and on the right, Building 7 shows small fires on two floors. Flames hardly reach the outside. The fire in Windsor Tower lasted for almost 24 hours before burning out. Cladding fell from the tower but the 32 story building still stood, its steel skeleton still standing. In contrast, Building 7 crumbled into dust after several hours.

Even though the fire burned for almost 24 hours, the skeleton framework is still intact and the building is still standing.
