I have this clip and a few others like it saved on my hard drive.
This isn't the only video out there of firemen saying there were bombs in the buildings:
www.whatreallyhappened.com...

"There's a bomb in the building - start clearing out"
"We were trying to get some of the people out, but then there was secondary explosions and then subsequent collapses."
"As we were getting our gear on and making our way to the stairway, there was a heavy duty explosion."
"We really never even got that close to the building. The explosion blew and it knocked everybody over"
That page also mentions how oral histories of 9/11 had redactions that apparently included, as per
court
orders, the exclusion of the opinions of firemen as to what brought the buildings down, or any other opinions relating to that day (the reason
apparently being that such opinions aren't factual enough to be released to the public).
