We don't do "night stops"..we fly all night ( interrupted by a couple of restfull hours in the Naha cell bloke) and then ,according to the Japanese, we are able to get 9 hours of sleep in the middle of the day at some crap, noisy hotel somewhere. We then sign on again at 2200 and do it all again..for 4 f@#$%g nights in a row. Yea, life's a gem here!
