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.
As the plane breaks apart, you have smaller pieces of the plane, but they are still moving at several hundred miles and hour until something slows them down...... it's like a blast from a massive shotgun

I agree.

Birds don't penetrate the plane.
