Here's a fun fact that may save someone's life someday.

Have you ever seen a high speed police car chase where the suspect's car just loses control and runs off the road or into a tree? Have you ever seen the result of a ONE car accident out in the middle of nowhere with no other vehicles around, where the car runs into a tree or light pole or something?

Well the reason is often (not always but more often than you know) the result of heat related tire sidewall failure.

The faster the car travels the more heat builds up in the tires. When the tires get warm enough the side walls no longer have the strength necessary to support the weight of the car and so the least amount of sideways momentum, as is experienced in just turning the steering wheel enough to keep the car going straight, can be enough to send the car careening out of control.

When the tires get warm enough the rubber becomes like jelly.

On every tire you will see, in very small print, it's heat rating. Expensive sports car tires have a higher temperature rating than family cars do. And they cost a lot of money because they are built to handle the higher temperatures and sideways pressures of cars going in excess of 120 MPH.

The average family car tire is only expected to experience heat that comes from driving at highway speeds. Faster than that, like in a high speed police chase or on a lonely road and the driver, often young and under the influence, speeding down the road to see how fast his car will go, will result in a crash.

The tires don't get so hot that they melt. They get hot enough to lose their strength and when their structural strength is weakened from the heat they can no longer support the weight or forces they could at normal operating temperatures.

Anyone who doesn't believe the WTC towers fell because the steel beams were weakened by the burning jet fuel should find a secluded road and go as fast as you can for a few miles.

And if we never see you post here again, we'll assume you learned the truth the hard way.

Buildings 5 and 6 did not collapse, yet those buildings were engulged with fire.

Huge Amounts Of Smoke Came From WTC 5 & 6 NOT WTC 7

These photos show that Buildings 5 and 6 were 12 strories high, and could almost entirely be reached with water hoses. There were substantial breaches to the outer shells of 5 and 6, so no heat was building up in building 5 and 6.

All the people had been evacuated from Building 7, and the fire hoses could not reach very far up the 47 story building. The upper exterior shell of Building 7 was largely intact. The intact upper exterior of building 7 held in the heat from the fires on middle floors.

The NYFD had no effective plan for fighting the multi-story fire in Building 7, there was already significant structural damage to a lower corner of Building 7, and a command decision was made that enough firefighters had already died on 9-11, so no efforts were made to combat the fire in Building 7.

Heat rises, and as the fire burned from at least 10:28 AM to 5:20 PM, the heat built up inside, and the heat rose to the floors above the fire in the building.

The NYFD could have done more to cool off Building 7, so maybe the NYFD wants to say they were surpriesd the Building 7 collapsed from heat build up inside the building.

It was not well understodd on 9-11-01 that Steel weakens when heated. It was not well understood, that as a fire burns on the lower floors of an office building, that the floors immediately above the fire will become overheated, lose their structural strength, and bring more weight to bear on the floor immediately below the fire, so that the weight of floors 20 through 27 will overload floor 20, and start a collapse. Floors 19, 18, 17 each will become succesively overladed and collapse.

I have seen several fires in high rise apartments, and the apartments are desiged to contain gthe fire within that one apartment. So the fire is encapsulated, and does not threated the apartments above or beside the aparment on fire.

For Office Buildings, there is no such copmartmentalization. One floor on fire, burns up to the next floor. Heat keeps building up, and weakens the steel and overloads the floor at the base of the fire.

Fire fighting efforts on Building 7 stopped at Noon, on 9-11.

The reports of pockets of molten steel being found days and weeks after the collapse of the WTC buildings may be inconvenient.

Context of '(5:20 p.m.) September 11, 2001: WTC Building 7 Collapses; Cause Remains Unclear'

The molten steel may have been created, perhaps in part, by the fire retardent material that is ordinarily sprayed on steel beams to insulate the heat from a fire on the steel beams. The fire retardent material when in a pile of rubble, with hot embers, may act as charcoal, to keep a hot fire going, and melt the steel, similar to a pile of mulch in spontaneous combustion.

Fire retardent material feeding a fire in a pile of rubble is an unusaual situation. What would the design correction be? Change fire retardent material to fire proof material? Asbestos was highly fire proof, but caused problems for humans in breathing Asbestos dust. The fire resistant spray-on insulation used on steel girders works fine for most real world situations.

Molten steel in a pile of smoldering rubble is not proof of the use of explosives. In buildings that are demolished by explosives, there is not a history of molten steel being found weeks after the demolition. Explosive charges for Demolition break the steel apart by large force, not be heating and melting the steel.

Still, Bush could have worked harder for Peace between Israel, the Palestinans, and Israel's Arab neighbors, when Bush first got into office. Rather, I personally believe that Bush was deliberately instigating conflicts between Israel and the Palestinans, to create his own excuse to involve the US Military in Iraq, as had been a long standing ambition of the Neocons. The burning and crumbling of the WTC Buildings on 9-11-01 was the answer to the prayers of the Neocons, just as Pearl Harbor was an answer to the prayers of those who were wishing for the US to enter WWII.

The deaths of Americans, and other nationalities, in 9-11 and Pearl Harbor 1941, were not exactly intended murder by Bush or Roosevelt, but the deaths were, in my opinion, a reasonably foreseeable risk of antagonizing Japan and the Palestinans. Motivating the US Congress to go to war, and continue wars, may, perhaps thankfully, take some special manipulation.

Bin Laden knew of the design discussions in whicht eh architechts represented that tghe WTC was designed to withstand the impact of a Boeing 707, 1/2 full of fuel, at 450 Miles per hour. So Bin Laden used 737 Planes, 7/8 full of fuel, at 550 Miles per hour.

The planes the flew into the WTC Towers were apparently Boeing 767-200 planes.

Do controlled demolitions ordinarily collapse at free fall speed, or might they collapse at near free fall speed?

Who are you referring to as "idiots"?

Jray

I wouldn't say 14 seconds is near the 9 second free fall collapse.

Travelsonic

Both towers were hit by 767-200s, Pennsylvania and the Pentagon were 757-200s. There were no 737s. Decent size/capacity/weight difference.

I never knew that we had knowlege of possible attacks before they occured.

So, Chanda, you believe the United States government was complicit in the 9/11 attacks yet you proudly display a Barack Obama quote? Way to fight the power.
