Bit of a boring video but the opinion of 1600 people with far more idea of these buildings than any of us.
Here is a wee thought for those of you who believe a plane or terrosist incident could bring these buildings down.
Following the 93 bombing which was carried out in the basement and was aimed at a particular section of the building.
Say someone in authority believed such an attack could bring these buildings down.
Now these buildings were roughly a quarter of a mile high.
If a bomb in a corner of the buildin either in basement or elsewhere in the building could cause the building to collapse what sort of devestation economical and life wise would a quarter of a mile building toppling sidewards cause.
Far far more than the 3000 that died and billions and billions of damage.
So someone gives the authority for the building to be secretly rigged for a controlled explosion so they come down in there own footprint as what happened on that day.
So planes hit and someone panics and thinks builings will topple do you kill 3000 OR believe if they topple it will kill 10000 plus and hits the button .
Feasible ??
No.
First off, I can't see youtube at the moment.
But anyway, explosives have a shelf life:
"For example some shelf lives are follows:
Maximum period
Delay electric detonators 2½ years
Detonating cord 4 years
Emulsion explosives 12 months"

Also, you ignore the fact that:
* There was structural deformation prior to collapse (something you would never see with a CD).
* The buildings did not fall into their footprint, and infact destroyed a number of building nearby (WTC7 was damaged and collapsed due to fire, WTC3 was destroyed), and:
"The U.S. Customs House (6 World Trade Center), 4 World Trade Center, 5 World Trade Center, and both pedestrian bridges connecting buildings were severely damaged. The Deutsche Bank Building on 130 Liberty Street was partially damaged and demolished later.[68][69] The two buildings of the World Financial Center also suffered damage.[68]
The Deutsche Bank Building across Liberty Street from the World Trade Center complex was later condemned as uninhabitable because of toxic conditions inside the office tower, and was deconstructed.[70][71] The Borough of Manhattan Community College's Fiterman Hall at 30 West Broadway was condemned due to extensive damage in the attacks, and is being rebuilt.[72] Other neighboring buildings including 90 West Street and the Verizon Building suffered major damage but have been restored.[73] World Financial Center buildings, One Liberty Plaza, the Millenium Hilton, and 90 Church Street had moderate damage and have since been restored."

And when WTC7 collapsed, it left debris on top of other neighbouring buildings. Hardly a controlled situation.
* The collapse began where the fire was raging. It is inconceivable that explosives and their fuse wires could survive an impact and the subsequent fire, and go un-noticed.
* The planting of any explosives in such a building would not go un-noticed, as it was occupied (as I have already shown). Not a single person has come forward to say they saw any such activity.
