"I can say with certainty there must have been explosive material that was set off in sequence. " - Mahmoud Ahmadinejad, President of Iran and engineer (PhD), claiming that jetliners were not the only reason the World Trade Center towers collapsed, 22 September 2011
"My opinion is, based on the videotapes, that after the airplanes hit the World Trade Center there were some explosive devices inside the buildings that caused the towers to collapse…It would be difficult for something from the plane to trigger an event like that." - Van Romero, explosion expert, “Explosives Planted In Towers, N.M. Tech Expert Says”, Albuquerque Journal, 11 September 2001
In an interview with the Associated Press on 22 September 2011, Mahmoud Ahmadinejad stated "as an engineer" that he is certain that there was explosive material involved in the collapse of the Twin Towers of the World Trade Center on 9/11. Ahmadinejad, who earned his PhD in transportation engineering in 1997, is certainly not alone in this opinion.
There are nearly 1,600 professionals at Architects and Engineers for 9/11 Truth who do not believe the official version and demand a "truly independent investigation" into what really happened to the Twin Towers when they were demolished with more than 2,600 people within them. But one does not need to be an engineer to understand that the Twin Towers were demolished with Thermite cutter charges and explosives. It is quite obvious from what we saw when the South Tower "collapsed".
I have been of the opinion that the Twin Towers and WTC 7 were demolished with explosives since 9/11 and have written extensively about the subject. The discovery of molten iron in the rubble and billions of "iron-rich spheroids" found in the dust of the demolished towers are proof that large amounts of molten iron were produced prior to the explosive demolition of the World Trade Center. A large cascade of tons of molten iron was seen falling from the 81st floor of the South Tower (WTC 2) in the minutes before it collapsed.

A sophisticated form of Thermite was found in the dust of the World Trade Center by Dr. Steven E. Jones of Brigham Young University in 2007. Thermite is an incendiary combination of grains of aluminum and ferrous oxide, which produces molten iron and aluminum oxide (whitish smoke) during an intense heat-producing (exothermic) reaction. Other elements can be added to the thermitic mixture to achieve different effects such as orange flames. Thermite cutter charges are thought to have been used to cut the 47 core columns of the Twin Towers causing them to collapse.
The exterior columns (blue) and the crucial 47 core columns (red), which supported the gravity load of the tower and which would have had to have been cut in order for the tower to fall - or for the top section to tilt and topple...
as it did in the beginning of the "collapse". The fact that this 30-story section is tilting and falling indicates that the 47 core columns on floor 81 had all been cut with Thermite seconds before explosive charges blew out the remaining exterior columns. The top section of the tower would not have tilted had the core columns not been cut.
Large amounts of white smoke, indicative of Thermite, were seen at the beginning of the demolition.
The top section was pulverized by explosives in mid-air hidden behind clouds of smoke and dust.
The photographs and videos of the collapse of WTC 2 indicate that a large amount of Thermite had been placed on the 81st floor of the South Tower (the computer floor of Fuji Bank) and that Thermite cutter charges were used to cut the core columns. During the cutting of the core columns a large amount of molten iron was created, some of which was seen falling from the damaged East corner of the tower. White smoke indicative of aluminum oxide was also observed coming from the floor.
Immediately after the cutting of the core columns with Thermite charges, explosives were detonated that severed the remaining exterior columns that supported the walls of the tower. These are clearly the events that initiated the "collapse" of WTC 2. Cutting the core columns and then the remaining exterior columns resulted in the 30-story top section tilting about 23 degrees to the South and East, where a large number of exterior columns were missing having been knocked out when the airplane crashed into the tower.

More than one-third of the exterior columns of the Southwest wall had been cut by the entry of the plane.
It is certainly not a radical opinion to believe that Thermite and explosives were used to demolish the Twin Towers; it is in fact the only explanation that is supported by the evidence.
