granted the bomber was a much smaller plane. But, the wtc towers were also much larger, more modern buildings, in fact designed to have a commercial jet crashed into them.
even given that, who knows. what about wtc7 though?

? the only modern skyscraper to have ever collapsed from fire alone, in a matter of hours no less.
also the Bank of america building in los angeles, an 850 ft skyscraper, sustained a major fire a while back about halfway up. something like 3-4 entire floors burned for like 2 days straight. the result? a burned out, beat up section, but a standing tower whose structural integrity was never in danger of collapsing.
again who knows but it certainly seems a bit strange
