i agree with you on the towers .........i make a living doing construction and restoration.....well heat is a magor factor in steel holding it's integerty........i think any steel building ,if expossed to that much heat would calapse.........the strenth of that building wasn't touched from the impact it was weak'nd from heat ......
i've done a few fire restorations and when you expose steel to extrem temts, the steel will warp and it will actually change in composition,.....on a fire restoration it's common to replace any steel that has been exposed to extrem heat......it changes it's integrety even if it looks fine........now correct me if i'm wrong ,steel is made by a heating process ......the process used is what determines it strenth......the difference between iron and steel is how it's made.......if you heat up steel and don't use the same process it will not be the same when it cools down it will be closer to an iron compound......... we all know iron is weaker so it's safe to say when steel is heated to near melting temps it will lose it's strenth
well the temps reached in the towers was definatly hot enough to heat the steel to near meling temps......jet fuel burns hot ......once the steel reached a certian temp it couldn't hold the amount of weight it was designed for.......thus the reason that the tower came straight down .....gravity......if the building was comprimised from the impact it would have fallen to the side instead of collapsing on it self.........

well thats my two cents any way
