Hi this is a part of the documentary which turned me on the side of the conspiracy theorists.. its a must see
This is footage shot across the river on a tripod which records all the massive explosions a few seconds before the tower collapses. the first 13 minutes is just unedited footage then it gets interesting as they do analysis and take out the lag for the sound delay. So it will be pretty boring untill then.
for those who are interested cheers..
also heres a little one of the building 7 demolition that also fell that day
