Secondary explosions caused lobby of World Trade Center to implode

Newly obtained video that was reluctantly released by NIST after a lawsuit by the International Center for 9/11 Studies shows two firefighters on 9/11 discussing how secondary explosions occurred immediately before the collapse of the twin towers, providing damning new evidence that explosive devices were used to bring down the buildings.
Debunkers have repeatedly claimed that low-temperature burning jet fuel could weaken steel support columns enough to cause the pancake-style collapse of the twin towers, ignoring the plethora of eyewitness testimony to incendiary devices having caused the implosion of the World Trade Center structure.
The new tape is as clear cut as it comes – the firefighters, who were inside the lobby of one of the towers, unequivocally state that secondary explosions which occurred after the planes hit were responsible for causing the towers to collapse.
“There was an explosion….the third explosion the whole lobby collapsed on us,” states the firefighter. Asked “was that a secondary explosion,” he responds, “yes it was ….definitely secondary explosion”.
Another firefighter then confirms that there were at least three explosions which caused the lobby to collapse.
The only way to explain what firefighters described as “molten steel, like you’re in a foundary, like lava” being witnessed following the collapse of the towers was if powerful additional incendiary devices were used to take down the buildings.
The firefighters’ testimony compliments that of William Rodriguez, eyewitness to sub-level explosions that occurred before the impact of the first plane in the north tower and representative for many 9/11 victim’s families.
Rodriguez’ testimony is also confirmed by Anthony Saltalamacchia, a morning supervisor who managed over a hundred workers in the twin towers. Saltalamacchia was in sub-basement B1 of the North Tower, approximately 1,100 feet below the airplane’s impact point at floors 93 to 98.
“The explosion….at first we believe it came from the mechanical room and then we heard a series of other explosions that sounded up on the above levels of the building,” said Saltalamacchia.
Saltalamacchia then discusses how a man ran into the office with his skin hanging off. William Rodriguez had previously described the same scenario following basement level explosions and it was also seconded by another eyewitness, Kenneth Johannemann, an employee of ABM janitorial services.
“As we’re standing there, more explosions were happening,” said Saltalamacchia, before he urged Rodriguez and the other workers to leave the building. The group left and initially headed towards the lobby before they realized it too had been partially destroyed, conforming with the eyewitness testimony of the firefighters.
Despite Saltalamacchia’s plea to stay out of harm’s way, Rodriguez ran back into the burning building in an attempt to save his colleagues.
“The amount of explosions I heard from 8:46 to the time we got out was so many – at least ten – it was just like multiple explosions to where I felt there was different grenades, that’s what it sounded like, like different grenades being set off in the building,” said Saltalamacchia.
“It was one major explosion and then there was different explosions throughout that period of time until we got out,” he added.
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.
In another clip, the entire collapse of the building is edited out, the audio is removed and only restored after the building has fully collapsed.
The Center also obtained videos of the collapse of the twin towers that had obviously been edited, with sections deliberately removed. “There are many video clips in the Cumulus database that do not show collapse initiation – the only event even purportedly explained in the final report from NIST on the Twin Towers,” states the Center.
Another new video shows Michael Hess yelling for help from the 8th floor window of WTC 7. The clip reinforces the fact that the building had not sustained any substantial damage before its free fall collapse within 7 seconds.
As we documented for several years, the collapse of WTC 7 is the smoking gun confirming that the official story behind 9/11 is bogus. The collapse of Building 7 was reported before it happened by several news stations, including BBC and CNN. 
Explosions in WTC 7 were also reported by eyewitnesses inside the building, including Barry Jennings, who described a “big explosion” that blew him back to the 8th floor.
Other videos show firefighters talking about how the “building is about to blow up”.
The International Center for 9/11 Studies is still in the process of reviewing over 300 DVDs along with several external hard disk drives that contain a plethora of unseen photographs and video footage from ground zero. Judging by the small amount of damning footage already released, it’s highly probable that this data will provide a myriad of new contradictions both to the official 9/11 story as well as NIST’s own investigation into the collapse of the three buildings.
