The case in question is the world trade center. I'm trying to debunk some people who are claiming that the windows blowing out as the building collapses indicate explosives. I believe this is caused by air pressure, however the conspirator has stated that it can only move as fast as the force pushing it, so just how fast will air pressure move if there is a sudden massive increase in air pressure?

it depends greatly on the source

Air pressure doesn't travel. The wavefront of a sudden change in air pressure travels at the speed of sound. At standard temperature and pressure, that's around 770 MPH. This is independent of the speed of the source of the pressure difference. The sonic boom is an example of this, where the source moves faster than the speed of sound.
The collapse of a high-rise building raises the air pressure on a given floor as that floor collapses, but that probably doesn't happen fast enough to blow out the windows.
Careful study of the video records of the World Trade Center collapses and of the chemical signatures of the remains shows some fairly strong evidence of explosive devices in addition to the jet fuel from the planes. If that is true, many people in a position of influence would not want the knowledge exposed. Power hinders truth.
