How Did Aluminium Plane Wings Enter the World Trade Center ?

speed is half the answer, the other half is that buildings just arent that strong against sideways force, they are designed to with stand gravity, and a certain speed of wind. certainly not a hunk of metal (any metal) sheering into the side at around 200mph did you know that you can fire a candle from a shotgun through a door? wax isnt very hard either.....

the question you should be asking is - if a boing 757 travelling at 500 mph smashed into 16ft thick steel rienforced concrete would it entirely disintergrate ? Yes most of the cockpit and 3/4 of the plane would because its made of 'framed' aluminium and certainly take out most of the front of the building engulfing it in flames and burn for quiet a while. BUT we are led to believe by the media that the pentagon was hit by the above mentioned plane and only make an 18ft hole in the front of the building with still some windows intact around the impact area !!!!!??? And where are the titanium encased engines !!!?? And why are the FBI holding video evidence which would clearly show a "plane" hitting it ,shot by a garage opposite the pentagon and a hotel across the street ???? where ? why ? because a plane didnt hit the pentagon and you'd be muppet to think it did !!!

Think of it like this - the wires holding up an oil rig are a couple of inches thick, hardly sharp, but they are held at incredible tension, so should one snap, as has been known to happen, the wire is going to flick itself about at incredible speed. Though a very blunt object in itself, at that speed it has an awful lot of energy in it, and will cut through most anything, including unfortunate oil rig workers who get in the way. The plane would bave been going a few hundred miles per hour, and would therefore slice easily into the building.

quickly

Simple, the aircraft were moving at over 500 MPH. That amount of kinetic energy cut the steel supports like a knife through spaghetti. Yes, if you could hurl a Big Mac at a tank hard enough you could take it out. The tank-killer rounds from an A-10 weigh less than a Big Mac. The Twin Towers were never designed to survive the impact of a fully fueled airliner at normal cruise speed. The possibility of an aircraft impact was considered in the design criteria and engineering analysis. It was assumed that it would be an aircraft at approach speeds (about 150 MPH or so) with a minimum fuel load getting lost in fog or other weather. The designers never imagined the reality of 9/11. Please don't get suckered in by the conspiracy theorists and their junk science and half truths. It was exactly as it appeared to be -- a terror attack by some whacked out zealots who proudly and publicly admit responsibility for their acts.

Momentum. Simply the force that an item has is based on a combination of mass and velocity. There are many experiments that demonstrate. And to explain further the structure of a building is designed to take forces of gravity and wind. The plane was simple like a bullet in the scenario.

Ever seen a piece of straw driven threw a utility pole by a tornado. It has happened

What were the explosions that could be seen on the opposite side of the tower as the plane hit.Why did a top american demolition expert say it was the best demolition he had ever seen. Why were offices nearby suddenly given evacuation training before the event. Why on that particular day in the year were americans the least nationality in the towers. How did a jumbo jet get through a hole about 12 feet round and leave no wreckage. Why did a guy about 1 mile from the pentagon hear a loud whoosh as he was walking along. You want an answer??? I think you aint going to get one.

Wings are NOT made of aluminum covered fiberglass on commercial aircraft. They are aluminum skins over frames and stiffeners, very beefed up, as in the leading edge.
