Well he has just coasted out over Japan, next option Hawaii, then press for Mexico or the USA.
His take off point was chosen in the centre of the USA to ensure that, even if he fell short, he would be overland with recovery options.
Two questions if anyone knows the figures. Will a 15% fuel deficit allow him to reach the west coast? If so, will it also allow the required distance to be covered, even if he does not reach his planned destination?
