Did a Boeing 757 Make This Hole in the Fence and Damage the Generator at the Pentagon?

What is apparent is that there is a large hole in the fence that surrounded the construction area where the Pentagon was hit. The hole is right at ground level, and is very similar in size to a Boeing 757 engine. Are we really supposed to believe that the starboard engine of flight 77 made this hole in the fence and also knocked the generator askew AND also smashed the top of the generator? Are we also supposed to believe the wing flap fairing made a long gouge in the top in the generator? Actually, Killtown does a pretty good job of showing how the gouge is not from a Boeing 757 wing here.

But here I want to ask: WHAT THE HELL MADE THE HOLE IN THE FENCE AND SMASHED THE GENERATOR?

It seems impossible that:
1) a 757 engine could have knocked the hole in the fence and then jumped up to only smash the top of the generator,
2) a 757 engine could have been so low to the ground to make this hole in the fence without the plane crashing before it reached the wall,
3) the impact of a 757 engine on the generator didn't cause the engine to break off the wing.

So the whole scene here doesn't add up. What on earth happened to create this damage pattern?

I hate to say it, but a large missile with short wings might better explain the damage pattern-- the missile body would have made the large hole in the fence and the wing could have smashed the top of the generator. It's not clear what made the gouge on the top of the generator, but perhaps this was done by part of the plane that came in right behind the missile?

It sounds crazy, but how else can we explain the damage?

The only other explanation would be that a 757 engine made the hole in the fence and was just extremely lucky not to hit the ground before this-- then the plane engine pushed the generator backwards while the wing above the engine and the wing flap fairings produced the damage to the top of the generator. The problem with this is that this severe impact would have had to throw the 757 off its path considerably, and cause it to impact further to the right of the impact hole. Plus, the engine would probably have broken off. Plus, the wing would have damaged a longer section of generator.

So again, this official story doesn't add up.
