Have you not listened to the first responders accounts regarding the sound of bombs ? How were the lobbies windows blown out and people with there skin hanging off in the lobby ...... do I need mention free fall speed collapse..... then the elephant in the room wtc7 office fires so paper and furnature fires bring a building down ?

One, there was no lack of rubble at the WTC. As documented by the loads of rubble taken to the lay down yards. Or the rubble pulled out of WTC basements.
Two, why would explosives make to little material. As in noticeable. That is more along the lines of Wood’s Dustification.
Three, where are all the loud booms from explosives indicative of explosions powerful enough to cut columns and throw beams?
Four, any demolitions shrapnel recovered from the WTC? The injured? Or with the human remains?
science is a wonderful thing explain to me then if there were no explosives how was free fall speed achieved

So? Guess you cannot cite a credible study proving thermite? Or any evidence of explosives from the WTC video? A supposed floor to floor CD system?
Debris from the collapse of WTC 1, which was 370 feet to the south, ignited fires on at least 10 floors in the building at its south and west faces. However, only the fires on some of the lower floors—7 through 9 and 11 through 13—burned out of control. These lower-floor fires—which spread and grew because the water supply to the automatic sprinkler system for these floors had failed—were similar to building fires experienced in other tall buildings. The primary and backup water supply to the sprinkler systems for the lower floors relied on the city's water supply, whose lines were damaged by the collapse of WTC 1 and WTC 2. These uncontrolled lower-floor fires eventually spread to the northeast part of WTC 7, where the building's collapse began.
The heat from the uncontrolled fires caused steel floor beams and girders to thermally expand, leading to a chain of events that caused a key structural column to fail. The failure of this structural column then initiated a fire-induced progressive collapse of the entire building.

3WHAT ABOUT THE ALMOST FREE-FALL COLLAPSE OF THE TWIN TOWERS? The key is the “almost” modifier. If I told you I was making almost $100,000 and you found out I was making only $67,000, you’d say I was exaggerating. So stop exaggerating the collapse speed of the WTC Towers! The 80,000 tons of structural steel slowed down the collapses of the Twin Towers to about ⅔ (two-thirds) of free-fall.3 And the core collapsed at about 40% of free-fall speed, coming down last.4 According to Richard Gage: “To bring a building symmetrically down, what we have to do is remove the core columns.” But on 9/11 the stronger core columns came down last, which violates this supposed most fundamental rule of controlled demolition.

The Windsor Tower was completely gutted by the fire on 12 February 2005. A large portion of the floor slabs above the 17th Floor progressively collapsed during the fire when the unprotected steel perimeter columns on the upper levels buckled and collapsed (see Figure 1). It was believed that the massive transfer structure at the 17th Floor level resisted further collapse of the building.

Well the Madrid Windsor did have a partial collapse above the 17th fool. A collapse stopped by a floor reinforced by concrete. Something the WTC buildings did not have.
The WTC buildings did not have traditional concrete cores that saved other buildings. The towers minimized cost by using less concrete than normal practices.
The towers had long floor tresses with no mid support that is common practice.
The long drooping floor trusses cooled and contacted. This pulled in on the remaining columns at the impact points. The columns bowed and then buckeled leading to collapse.

No audio of explosions or evidence of pressure waves with the force to cut columns in the areas of the original isolated areas of buckling. In fact, the start of collapse is everything being pulled into the tower.
How did they explain the premature BBC announcement? I never heard the explanations.
Even better the lack of any real wreckage in the one that went down in was it Pennsylvania (forgive my memory plus I'm in Australia) now that was a ripper excuse .... the plane " buried itself" now that's magic unicorn stuff right there
Nice try explaining the collapse of WTC building 7, by comparing it to the WTC Towers (2)
So ok... debris flew 370 feet, igniting fires in wtc7. Ok the sprinklers were out and the city's water system was damaged due to the collapse of the towers.
Somehow the firefigthers didn't think about pumping sea water from the very nearby ocean to extinguish the "uncontrolled fires" on the lower floors in wtc7. Why ? Was it because the decision "to pull", was already made, and any attempt to save the building was ignored from then on. Yea, who cares.. just let it burn... why?
.
The force of the explosions at the World Trade Center had ruptured virtually every water main in downtown Manhattan, leaving firefighters with no water, and no way to fight the fires raging in the buildings left standing in World Trade Plaza. Since the Fire Department had only two under-sized fireboats, and its fire engines were worthless, the Harvey was now an answer to a fireman’s prayer.
Pulling up to the seawall in North River, the closest proximity possible to the World Trade Center, the Harvey set up alongside the Fire Department’s other two fireboats to begin her work. Fire hoses were quickly run from the Harvey to the World Trade Center, and the firefighters were able to put down the remaining fires, saving everything but World Trade Center 7, which collapsed later that day.
The Harvey worked non-stop until Friday night, September 14, when water service to the City’s fire hydrants was restored.
All pumpers now have 2,000-gpm pumps with five lengths of hard flex suction hose and special intakes for drafting. This idea stemmed from the water main collapses that prevented firefighters from flowing water at Ground Zero. Now, every FDNY pumper ordered since 9/11 can draft water from any of the nearby rivers and supply other units on the scene.

Great I've been telling our kids nineteen Arab hijackers, who couldn’t fly one-engined Cessnas, flew wide-bodied jets in a way that professional wide-bodied jet pilots have said they could never do......Santa ,now this, there not going to believe anything I say anymore..
who couldn’t fly one-engined Cessnas

WTC 7 had fires burning for several hours and damage done by the North Tower collapse.
20 floor rip on elevation facing north tower and other damage seen on this video.
