49. Think about it this way

Regarding floors collapsing above fire floors, try this (thought!) experiment
1) Place a ten iron weight on your head.
2) Record the amount of pain you feel
3) Take the same ten pound weight and hold it ten feet above your head.
4) Drop the weight on your head.
5) If you are still conscious, record the amount of pain you feel.
6) If you are not dead, go to the hospital, you probably have a fractured skull.

For length of fire - fires in World Trade Center burned about an 1 hour. This is also about the time that the maximum temperature in the Cardington Fire Test was reach, with a fairly rapid drop off after that.

Heatsink effect - I don't think you understand how a heatsink works. I suggest you read Transport Phenomena, by Bird, Stewart and Lightfoot, which is the standard introductory text for topics such as heat transfer.


I also suggest you read more about the Cardington Fire Tests here:

Reading these references will help make you a better conspiracy theorist.
