There is a major flaw in this theory. That is WTC 7 which collapsed at free fall speed into it's own footprint with no aircraft or other aluminium sources in the building. Explosionns were also heard and seen in WTC 7
That's not a flaw at all.

WT7 burnt out of control around 8 hours as there was bugger all water and after being severely structurally damaged by the collapse of the North Tower.
https://en.wikipedia.org/wiki/7_World_Trade_Center Quote: After the North Tower collapsed, some firefighters entered 7 World Trade Center to search the building. They attempted to extinguish small pockets of fire, but low water pressure hindered their efforts.[41] Over the course of the day, fires burned out of control on several floors of 7 World Trade Center; the flames visible on the east side of the building.[42][43] During the afternoon, fire was also seen on floors 6–10, 13–14, 19–22, and 29–30.[38] In particular, the fires on floors 7 through 9 and 11 through 13 continued to burn out of control during the afternoon.[8] At approximately 2:00 pm, firefighters noticed a bulge in the southwest corner of 7 World Trade Center between the 10th and 13th floors, a sign that the building was unstable and might collapse.[44] During the afternoon, firefighters also heard creaking sounds coming from the building.[45] Around 3:30 pm, FDNY Chief Daniel A. Nigro decided to halt rescue operations, surface removal, and searches along the surface of the debris near 7 World Trade Center and evacuate the area due to concerns for the safety of personnel.[46] At 5:20:33 pm EDT (according to FEMA), the building started to collapse, with the crumble of the east mechanical penthouse, but differing times are given as to what time the building completely collapsed: at 5:21:10 pm EDT according to FEMA, and at 5:20:52 pm EDT according to NIST.[6][7][47] There were no casualties associated with the collapse.
Quote:Few photos and video clips exist that show the damage sustained to the south face of 7 World Trade Center on 9/11. An ABC News helicopter captured footage of the south face of 7 World Trade Center, including a glimpse of a gash, extending approximately 10 stories.
