Its "The Twist" that scared me
Flying in and (4 hours later) out of Beijing, the 777 was twisting in the wind sheer; looking along the cabin from near the back, you could see the whole body pivoting +/- 15 degrees around the upper edge of the main frame, with the overhead compartments seeming to stay still and emphasis the twist.
Not sure if this was entirely a weather issue, as the previous flight in and out on a 747 was as smooth as silk
Our China Southern 777 also had dodgy brakes; on landing it would veer violently to the right every time the brakes were applied; even the stewardess liked scared (she was sat facing me); I was on board for three legs, Nanning - Guangzhou, Guangzhou - Beijing, Beijing - Shipol, and she had a death grip on her harness every time.
