Flew the 788 from MEL to AKL...its rattles and creaks quite a bit in the back, well, through the whole ac in turbulence. The center overhead compartment is attached in the center, and was wagging like a yodelers uvula in turbulence.
What is really disturbing was on rotation, the wings really flex up and down until enough speed has settled them down, like an albatros taking off....there was a very apparent up/down motion in the rear of the ac....
the dragon painted down the side seemed very appropriate....
