A man who was working in the World Trade Center on 9/11 has told WeAreChange.org that he personally witnessed explosions in the lobby area after he left the building to buy hot dogs at the same time that the first plane hit the north tower.
Watch the video.
"Once the plane hit the top, that's when the bombs started going off on the first floor," said Dean Brown.
"It's like the plane actually hit the first floor."
"You were hearing boom, boom, boom, boom from the top floor all the way down to the first floor."
The eyewitness also describes talking to devastated firefighters who told him there were bombs in the building.
