Only thermite (used for controlled demolition of a building), melts steel. Not one high rise building in history has collapsed on its footprint just by fire because it doesnt burn hot enough to melt steel.

Ha, N! My stats are quite similar. just over 12 answers a day and a question every 4.3 days. eeeek.

Anyway, i'm off to put me anorak on and read a few railway timetables...........

Dpuglas, perhaps you and I should join Zacs with his railway timetables. :o)

no one's mentioned the aliens on the towers before they collapsed?

The steel in the twin towers DID NOT MELT !!!
What happened was that the temperature reduced the structural strength of the steel to the point where it could not support the load of the buildings. Steel melts at 1200 deg C , the temperature of the burning building reached more than 600 deg, at that temperature the strength of the steel frame was no longer sufficient to support the weight of the building, so it collapsed.
Read this, structural steel begins to lose it's strength at temperatures above 300 deg C , the fire in the twin towers was over 600 deg C !

Old_geezer. The firefighters that were searching ground zero and were interviewed mentioned as well as the sound of explosions. Why would they lie about both of these things.???

Don't keep us in suspense, Nay37. What do you think happened?

By the way, Thermite is NOT used in the demolition of buildings!
Shaped explosive charges are used to cut the steel supports so that there is a controlled collapse of the structure.
Thermite was used to weld railway lines , it has not been used in demolition.
I was works metallurgist for an international company that made steel cranes. I do know a bit about the strength of steel.

''Not one building in history has collapsed on its footprint just by fire because it doesn't happen''
This video and the hundreds of other videos and links on Google must all be fakes then!

Do you believe that the Moon landings were faked and that the Earth is flat? You certainly share the same level of intelligence with those who do!

''Only thermite melts steel'' Oh dear then I must have been dreaming when I daily melted steel samples in my laboratory furnace to do an analysis then.

Hmmm, you hint at knowing of the secret underground railway network Naomi and for that, even just a hint, you should expect a visit from one of our public interface representatives.

Nothing to worry about, nothing at all.

Mwaaaaaahahahahahaha etc.

Probably, but you should keep a warm coat to hand, you might need it on an unexpected road trip. :-)

twin towers - o m g
arent we timed out ?

Hey Lord Kelvin predicted in 1890 that the twin towers would fall as they did - hey no ballshot !

some building are so heavy that they have no alternative but to fall on their foot print - because the turning moment necessary to topply them sideways is too great

and yes at the time I am afraid
engineers were saying that the heat was great enough weaken the structure sufficiently for it to collapse

yeah but Thermite WAS used in the terminator tv series to liquefy bits of aliens !
