Okay, you've stopped reading for understanding. Fuel-air explosions are a thing; we base automobile engines on them. I think I've stopped explaining, since you aren't listening.
You think an explosion is going to instantly heat the structural steel to weaken it that much? It's not just temperature but heat. It's takes a lot of sustained heat. The black smoke tells you the fires were burning poorly anyway.
Do your due diligence then.
What would I read that would be inconsistent with what I said? I think I've shown that your assessment is shaky.
Damaging explosions where I said they were.
