Sure.
You don't have to take an anon word for it, see what Mr Jones has to say about it.
The Role of Mass And Energy
When a light car and a massive truck collide, momentum conservation requires that the change in Mtruckvtruck = the change in Mcarvcar...
Note that an object with large mass will experience a smaller change in speed than the object with the small mass. As the occupant of the vehicle it is in your interest that the vehicle does not undergo big changes in speed in a short time.
If the vehicle comes to a stop, or if the speed is substantially decreased, the lost kinetic energy of the vehicle transforms into some other form. This process will involve work, the integral of force with respect to displacement. The bigger the displacement the weaker the force (and damage and injury). Hard stationary objects don't allow much displacement and cause more damage and injury than soft, movable, or breakaway objects. The next time you are driving or riding in a car, look around and see how modern vehicle and highway designs surround you with soft, breakaway barriers whenever possible—wide medians, breakaway lampposts, energy-absorbing barriers at underpasses, padded dashboards.

The steel in those towers, having more mass, will have less displacement than the plane, thus the plane would experience more damage than the steel, thus the plane CANNOT cause the steel to fail, just as in the example the small car would not destroy the truck.

More than 4,450 pounds of dynamite...25,000-ton concrete roof crashed down, shooting a cloud of fine white dust into a blue sky

Steven Jones, the truther?
I should have been more clear...sourcing someone like jones isn't acceptable...if thermite explodes, he and a few truthers wouldn't be the only people who know about it.

1-The steel in the entire tower means nothing, since it only contacted a small area. NOW do your calc, using the correct factors.
2-Lexan goes 4" into an aluminum block commons.wikimedia.org...:SDIO_KEW_Lexan_projectile.jpg
3-The impact wouldn't, true. What happens if the car hits the fuel tank, and the truck catches fire? Is the truck destroyed by the fire? or the impact? Or by a combo?

Lexan is NOT just plastic. It's highly dense and strong and was moving at 15,000 mph.

If we use a comparison to Seattle Kingdome demolition, the SEATTLE PI says it took.

If this is used as a rough estimate, for the concrete, one only needs to use this model for the WTC.

Interesting that CDI was also contracted for debris removal at Ground Zero, yet no information for that cleanup appears on the site.
