Video: 9/11 Firefighters Reveal Huge Explosions Before Towers Collapsed 4/5

Numerous other WTC basement workers, including Felipe David and Salvatore Giambanco, have also gone public with eyewitness testimony concerning massive sub-level explosions that took place before Flight 11 hit the north tower.

WTC construction worker Phillip Morelli was headed for level B-4 in Tower One [north tower], four stories below ground, when he was thrown to the floor by a violent explosion that coincided with the plane hitting 100 floors above.

15-year WTC worker Marlene Cruz told Peter Jennings in an interview with ABC News that she was also rocked by an explosion in the basement level of the north tower.

The 9/11 Commission completely ignored the hundreds of survivors, professionals, first responders, firefighters and police who reported numerous secondary explosions at all levels of the twin towers.

After filing a lawsuit that prompted NIST to release more than 3 terabytes of photographs and videos from their investigation into the collapse of the twin towers and WTC 7 on 9/11, the International Center for 9/11 Studies obtained evidence, in addition to the firefighter tapes, that suggests NIST edited several videos of the collapse of Building 7 in order to hide evidence of a controlled implosion. Building 7 was not hit by a plane and yet it collapsed demolition style late in the afternoon of September 11.

The Center filed a FOIA Request with NIST on January 26, 2009, seeking production of “all of the photographs and videos collected, reviewed, cited or in any other way used by NIST during its investigation of the World Trade Center building collapses.” Following several unsuccessful attempts to get NIST to even acknowledge receipt of the Request, the Center was forced to file a lawsuit on May 28, 2009. Shortly after the lawsuit was filed, the Request was assigned a reference number, and NIST began periodically releasing batches of responsive records.

The Center has now begun posting some of those images and videos online, the first batch of which is from an external hard disk drive “NIST WTC Investigation Cumulus Video Clips.”

In one of the clips, the video of which has been in the public domain for years, a loud, low-frequency boom can be heard just before the east penthouse of WTC 7 falls. Once the support columns that held up the penthouse are taken out, the rest of the building falls almost within its own footprint.

However, in subsequent clips released by NIST (National Institute of Standards and Technology), where the camera is located nearer to the building, the collapse of the penthouse is clearly edited out of the footage.

“Several clips from the Cumulus database show signs of editing. In the two video clips below, the collapse of the penthouse of World Trade Center 7 is cut out of the video. These videos happen to have been filmed from close to WTC 7, and have a high quality soundtrack that would have picked up explosion sounds from the charges that severed the columns supporting the penthouse, especially the explosion heard in the last video clip presented,” comments the International Center for 9/11 Studies.
