Here's an interesting eyewitness report about a large explosion at ground level right before the collapse of the North Tower. The witness is apparently a New Jersey musician.

"I'm not a conspiracy theorist; I don't go in for that junk. I'm very patriotic, and I believe in my elected officials -- I even write songs about them. But nothing said in the official (and largely unpublicised) story about the cause of the collapse of World Trade Center Seven jibes with what we witnessed that day. If the government story of the events at the Twin Towers have always seemed fishy and incomplete, I know damned well the few official accounts of the collapse of Building Seven are fishy and incomplete.

Just before the fall of the North Tower, we saw a large explosion coming from the street-level area around World Trade Center 7. I remember thinking that it looked distinctly like a bomb had been detonated underneath the city, and, of course, that's exactly what I thought had occurred.

I don't know what happened at WTC7, but everything I witnessed suggests strongly that the official line is dead wrong. No plane slammed into the skyscraper, and when it fell, it fell exactly as it would have if it had been demolished by contractors. The debris fell in a straight cone, directly onto the foundation of the building. Media silence about the collapse has been frightening in its totality; WTC7 is almost never discussed, and on the few occasions when it is, the FEMA line has been repeated more or less unquestioned. More bothersome to me is that the strange explosion I saw coming from Building Seven between the Tower collapses has never, to my knowledge, even been acknowledged by the city or the government."
