Update: Here is a response video I made after this reply.
Clarifying the Collapse Time of WTC 7
Two Seconds That Will Live in Infamy (June 2009 Update)
"A demolition that is planned as part of a covert operation to fit a narrative of events that attributes the total destruction of the building to a different cause (such as a jetliner crash and consequent fires) has a very different set of requirements than a demolition that is planned to legally remove a building in an urban setting. An examination of the technologies of energetic materials and wireless detonation available to insiders who had the means to coordinate the attack of 9/11/2001 suggests plausible scenarios by which the Twin Towers and Building 7 might have been subjected to controlled demolitions on 9/11/2001." - Source: http://www.911review.com/means/demolition/covert.html
Controlled Demolition Not Possible?
Waiting for Seven: WTC 7 Collapse Warnings in the FDNY Oral Histories
The demolition expert in the video above does not think the Twin Towers were controlled demolitions due to their unconventional nature, but again this goes back to this being a covert operation, visit this link for more info. And despite claims to the contrary, he is quite sure WTC 7 was a demolition. Perhaps the more conventional nature of WTC 7's demolition can be explained by evidence that indicates 10:45 a.m. was the originally planned demolition time.
