The best 9/11 video that you are ever likely to see.

[Blue in the Face]

If you are going to have a conspiracy of blowing up a building, why would you bother to tell a news agency before it had blown up(adding another group of people into the conspiracy)?

There's a lot of cause to be suspicious. The the building 7 BBC bit doesn't add to the cause. The wider the web of people who were "in on it" gets the more implausible a valid conspiracy becomes.

The vid in the OP revisits questions that a lot of people have had from day one though. Are there any valid answers out that disqualify these questions?
