There are examples of building who burned for 20 hours without failing. The fire melt / weaken steel does not make sense, it just doesnt if you look at it with an open mind.

Check this video of the windsor tower in madrid which burned for more than 20 hours, engulfed in flames.

The impact of the planes did little damage, tests have shown that the impact did not make more damage than high velocity winds which the towers where build to withstand, not to mention they where built to withstand multiple airplane impact.
