Most of us would agree that planes are flimsy things, as Marcus Icke points out: “Computer simulation and mathematical analysis of the impact by MIT, University of Purdue and others indicate that upon impact the wings of the 767 would have shattered and the fuel ignited outside the towers facade, the aircraft would have lost about 25% percent of its kinetic energy on impact and that the tail fin would have sheared off due to torsional forces. In layman’s terms this means that the aeroplane would have decelerated sharply [emphasis added] crumpled up and exploded against the tower’s wall with only heavy objects like the engines and undercarriage puncturing the towers facade. The entire airframe would not have glided through the outer wall and would not have left a large hole roughly the same shape and size of a Boeing 767-200.” Icke’s accompanying photos support his analysis by showing a MD80 landing hard, with its air frame bending and tail breaking off.

Good questions, but I think the "no-planers =disinfo" people will be arriving shortly.
I think everyone agree's something strange is happening with the pentagon. The WTC, on the other hand... I think the truthers believe planes hit, and the trusters do as well. The truther's believe that the no-plane is a disinfo ploy, designed to discredit truthers...

It is incredible though how the two twin tower planes, wings included, cut through the tower steel like butter.. The Pentagon was totally different.. The two things that should have penetrated the most, that's the 2 x 3500kg engines apparently disintegrated on impact while the flimsy fuselage penetrated 3 walls deep...

I think the planes could probably cut through the steel beams due to the enormous amounts of energy involved in the collision, but I find it odd that 2 buildings can take asymmetrical damage and fall symmetrically. I would think that if the supports are weakened on one side, if it collapses, wouldn't it fall towards the path of least resistance?

Commercial aircraft are not designed to be missiles which easily penetrate steel reinforced structures, while traveling well below subsonic speed. Where are the seat parts, luggage, cabinets & personal effects from the airplanes?
As for the nosecone strikes, has anyone ever considered building an airplane proof skyscraper out of bird bones? Seems to be a lot stronger than thick steel construction beams.
Exactly what I say too.

We're not talking about a bird here.
We're talking about a 125 ton (possibly heavier) mass of airliner flying at 400+ miles per hour.
The argument is bunk, because if the soft flesh and bone skin bird can do that to something much harder when colliding with it at speed, then why would anyone think a 125 ton mass travelling at 400mph+ couldn't punch a hole through the side of a box steel frame?
Its arguing against its own point.
If a large commercial aircraft really caused that damage, do you think the damage would be so orderly? Certainly, the shape of the damaged building section would be much more irregular.

look at the imprint the 'plane' has made in the picture of one of the twin towers. doesn't it look contrived with all its vertical and horizontal 'cuts'. there is also a picture showing a poor unfortunate looking out of the distruction virtually unscathed when it is difficult to believe that anyone in the immediate vicinity of a massive fireball could have survived. i believe there is evidence to suggest that the crashes were a digital manipulation.

In answer to the OP, the reason the plane cut through the buildings is SPEED and RIGIDITY.
How do tornadoes do some weird things, like drive straw into trees, strip road pavement and drive splinters into bricks? The list of bizarre things attributed to tornadoes is almost endless. Much of it is folklore; but there are some weird scenes in tornado damage. Asphalt pavement may strip when tornado winds sandblast the edges with gravel and other small detritus, eroding the edges and causing chunks to peel loose from the road base. Storm chasers and damage surveyors have observed this phenomenon often after the passage of a violent tornado. With a specially designed cannon, wind engineers at Texas Tech University have fired boards and other objects at over 100 mph into various types of construction materials, duplicating some of the kinds of "bizarre" effects, such as wood splinters embedded in bricks. Intense winds can bend a tree or other objects, creating cracks in which debris (e.g., hay straw) becomes lodged before the tree straightens and the crack tightens shut again. All bizarre damage effects have a physical cause inside the roiling maelstrom of tornado winds. We don't fully understand what some of those causes are yet, however; because much of it is almost impossible to simulate in a lab.
The purpose of all that focused power is brutally obvious: to break bones and rupture tissue. But success also depends on more subtle forces. Solid as they seem, all materials are at least slightly elastic. Whack them in the right spot and they will start to oscillate. A punch with a follow-through would dampen such oscillations, but a karate chop, by pulling away at the last moment, lets them move freely. "If you tweak a rubber band it goes up and down, and the same is true if you tweak a board or a brick with a much greater force," Feld says. "When they reach their elastic limits, they start to yield. In other words, they break."
The straw penetrates the potato easily because it is a strong cylinder made from thin plastic which also
