The airplane is fake. There is no way to be swallow completely inside the building. At least half of it have to be exploded outside with debris all around. If you watch carefully part of the plane disappear before the impact.

What are you basing this on? I mean how often have you seen a plane hit a building?
I think the key factor momentum. The weight of the plane and the speed of the plane.
Think of a car hitting a chain link fence. At 10 mph, the care won't go through the fence. Maybe not at 40 mph. But what about 100mph? There's a point where the fence won't stand a chance and the car will just bust though
The bird thing makes it easier to comprehend that a "soft" metal (aluminum) can penetrate a hard metal (steel). If a soft body (bird) can damage a plane as it does, then a plane can damage a building as it did.
The mass of the steel and concrete building is over 1000x more than the plane and would absorb the energy of momentum of the plane without such significant damage. If you want to talk about the heat of the burning fuel weakening the steel, jet fuel is volitile, spreads out quickly and burns way too fast to transfer enough heat soak into those MONSTEROUS steel beams to weaken them. Case in point: heat treating furnaces will burn billions of BTUs over many many hours to get such enormous steel components to 1500deg, which is nowhere near the temperature where it weakens. Yes, hand-held torches can cut through steel, but that is an EXTREMELY localized heat source intentionally applied. Not like throwing jet fuel on a beam and lighting it. The steel beams are also coated for fire protection and the other building materials, floor coverings and even the furniture are all fire rated to slow the propagation of a fire, not feed it. None of these things alone would matter much, but adding them all together makes the difference to slow the heat transfer to the beams, allowing the fuel to burn out before the beams could get hot enough to weaken.

Think of a flock of birds hitting a plane and then revise your statement.
I don't think my statement needs revising. The momentum will be on the plane's side. What's the point you are making.
