Video of a Wing Stress Test of a Boeing 777

I saw this video a while ago and it really is impressive.

What is even more interesting to think about is that this stress was applied in a controled lab environment, and for what I can tell, the actual fuselage was secured to the ground. I seriously doubt that and real experience could cause a wing to flex that much as you would have an equal and opposite reaction which would make the entire plane move opposite to the force and thus reduce the load on the wing that was flexing.

I watched a show on the A380 and they were saying that under normal takeoff load the wing flexed 12-20 feet (or something like that).
