You're very funny ... I see that you do not even know what a jet stream is (I understand you, it's easier to be ignorant) ... you do not realize that both the helicopter map and the geocentric are made by a heliocentrist .. On the other hand, you are admitting that the trip is west to east ... for the other questions, I add two more for you to remain ignorant: Because clouds, which are denser than air and gravity do not Pull down, take the curved shape of the earth? And why is there an Antarctic treaty in which no civilian but freely see the Antarctic?

PS: I'm still waiting for someone to go around the world from North to South ... but we already know that this will never happen ...

PS2: A jet streams can improve the speed between 200 and 400 km / h.

PS3: For your trip to be valid, you should start from the west and go to the east (or vice versa) in a lateral way and not in a circular way, and finish in the same place from which you started (the same for the case of North to South, only in that case it is up or down).
