That's a good point and I'd like to see Peter answer it. If the building swayed a few minutes before the collapse that's a sign it was failing internally. Now that could have been from cutter packs weakening the support columns. But it could also be from progressive natural failure. The controlled demolition version requires a hybrid installation of explosive charges and thermite packings that would be pretty extensive in their installation.
It is possible the Banfield audio is capturing the progressive collapse of the East Penthouse support core. Precise timing now comes into play. This internal collapse would explain the filling-in of the clear air horizon with smoke in the Banfield video as the building stood.
It's also possible those are demolition charges.
