World Trade Center Fire
The February 13, 1975 North Tower Fire has been carefully hidden from you. Here are a few reports concerning it.
Also, from the New York Times (Saturday 15th February 1975):
More from the New York Times (Saturday 14th February 1975):
|So, this was a very serious fire which spread over some 65 per cent of the
eleventh floor (the core plus half the office area) in the very same
building that supposedly "collapsed" on 9/11 due to a similar, or lesser,
fire. This fire also spread to a number of other floors. And although it
lasted over 3 hours, it caused no serious structural damage and
trusses survived the fires without replacement and supported the building
for many, many more years after the fires were put out.
It should be emphasized that the North Tower suffered no serious structural damage from this fire. In particular, no trusses needed to be replaced.
That the 1975 fire was more intense than the 9/11 fires is evident from the fact that it caused the 11th floor east side windows to break and flames could be seen pouring from these broken windows. This indicates a temperature greater than 700°C. In the 9/11 fires the windows were not broken by the heat (only by the aircraft impact) indicating a temperature below 700°C.
So now you know that the WTC towers were well designed and quite capable of surviving a serious fire. I repeat that this was a very hot fire that burnt through the open-plan office area of the eleventh floor and spread up and down the central core area for many floors. This was a serious fire.
Much was learned from the 1975 WTC fire. In particular, the fact that the fire had not been contained to a single floor but spread to many floors, caused much concern. The points of entry of the fire to other floors were identified and the floors of each building were modified to make sure that this would never happen again. For some strange reason, the modifications failed to perform on September 11, 2001 and again the fires spread from floor to floor.
