The collapse is mostly obscured by WTC 1. Explosion audio pre-collapse doesn’t match with other videos of the event. See also his unique footage of the WTC 7 collapse. Rick once operated 911researchers.com, now dead. Also see 911raw.com, where he has sold his lengthy footage on DVD. His documentary video was narrated/produced with investigative research by Dave Shaw.
His WTC 1 collapse footage was used in the popular Truther documentary “9/11 Mysteries,” with different audio added, including other explosion sounds and sirens (see video). That prompted a legal battle by Rick, who won the lawsuit against Sofia Shafquat/Avatar LLC. This touched close to home when my YouTube channel got a copyright strike or two, eventually cancelling/deleting my 2 channels with about 1,000 videos, for my uploading “9/11 Mysteries,” which was removed by YouTube for a copyright claim by “911 Eye Witness.” “9/11 Mysteries” can still be found on YouTube despite Rick’s efforts.
Notice in YT link 1 above how the [NYPD] helicopter is accused of somehow starting the demolition because of a flash or reflection off of it. That theory is not supported by most 9/11 truthers.
My investigation/discussion is at pumpitout forum (video links dead). The audio is in question due to deep explosion sounds, as analyzed by www.mediumrecords.com/wtc/audio02.html (where you can download the Siegel clip). Quoting the audio engineer at mediumrecords.com:
The dramatic nature of the blast sounds which occur in the 4 minutes prior to the collapse certainly raises some puzzling questions. Since other long stretches of unedited pre-collapse footage (with audio) from other angles has not yet been made public, it is not possible for us to hear if other recordings also caught these blasts. In other recordings from closer to the tower, though only short snippets are available, we don’t see much of any indication that intense explosions have be registered [sic] by any people in the area.
Certainly this webpage can help address the question of existing video with audio in the minutes before the first “collapse.” See also this website’s extensive 9/11 TV archive. Why is the video record near the towers so slim during this time period? (UPDATE, post-NIST FOIA from 911datasets.org and ic911studies — the video record isn’t slim, is it? Was all the other footage with audio tampered with, or somehow unable to pick up the noise [supposedly] recorded by Rick? Or did Rick add his explosion audio and later use the “9/11 Mysteries” audio switch as a clever disguise for relevant online queries?)
