op, pic related, according to the lead Structural Engineer in charge of the design and development of all the WTC structures, even a jumbo jet crashing into one of the towers would not cause a structural collapse, but the fuel which flooded the building would cause a fire that killed many people (but this fire would not cause a collapse, even after an airplane impact).

The lead engineer said this in 1993 after the first WTC bombing and pic related.

It's extremely unlikely that WTC 7 collapsed due to fire.

It's also extremely unlikely that WTC 1 and 2 collapsed solely due to 1 jet liner crashing into each of them, since this was specifically accounted for in their design by the engineers in charge.

(Pic related, BTW this article is from 1993 so it's not an "after the fact" claim, it's the head structural engineer stating outright that jet liners crashing into the WTC 1 and 2 were specifically accounted for and that this could not cause them to collapse. He also explicitly states that demolitions could bring the tower down, though.

People in this thread have said "ask a civil engineer."

The word of the head engineer of the WTC buildings back in 1993 after the first bombing happened and failed to cause a collapse was that:

1. Basement bomb can't cause collapse.
2. Jet liner impact + fire (he explicitly talks about the fire that would follow).
3. That top demolitions experts, on the other hand, could bring the towers down.

WTC buildings were specifically designed by the engineers to withstand and survive impacts from jet liners and the ensuing fires that they would cause. In 1993 after the first WTC bombing, a WTC engineer came out and specifically stated that:

1. Jet liners crashing into WTC would not compromise WTC, and that they specifically designed the towers so that they could withstand the impact, damage, and ensuing fires.

2. That said, demolitions experts could still bring WTC down with shaped explosives.
