Oh Boy
Good question. I wish to know where is that pub.
Just to help you, think why nobody sends spacecraft into orbit towards west i.e. a sunset.
Roughly the only difference is the weight of the flying object that will vary due to different centrifugal force as a result from difference in the total of ground speed + long. vector of speed of rotation. This vector is zero if you fly north south, or if you above north or south pole.
So Concorde was little lighter (with the same weight) coming back home, while ordinary jets flying from MIA to LHR may be lighter just under 1 %.
Milt RTFQ.
