Why were there no shock waves when the planes hit the Twin Towers?

Question

A 9/11 documentary showed up in my YouTube recommendations so I decided to watch it. As I was doing so, I realized that there were no shock waves when the planes hit the towers. You can hear the sound of the explosion travelling, but no massive window smashing/shattering like in the Oklahoma bombing or the Beirut explosion or even the [Black Tom explosion](https://en.wikipedia.org/wiki/Black_Tom_explosion#Explosion).

Why weren’t windows in New York blown out en masse that day? Was it due to the nature of the explosion? Thank you in advance!

Answer 1

Because it’s a crash. The fact there were no Shockwaves is another argument against the conspiracy nuts.
