Here is the ANA flight we took to China (which I nicknamed the vommit commet). The plane ride was absolutely brutal. It felt as though the pilot wanted to test the 767's capabilities to do barrel-rolls. The last 30 minutes of final descent had me clutching my emergency barf bag. I wanted to look out the window to see Mainland China, but the mere act of doing so pushed my lunch up into my throat as the plane cabin jostled back and forth and dropped altitude as if you were on a rollercoaster. I was very grateful when the ride came to an end.
