Well if drone can fly by battery power why can't planes eventually run on batteries.

They already can. Just not for very long

Solar Impulse 2, did OK


You do know why it flew in the direction it did?
You won't see a return journey from it.
Hot air balloons did it quicker with more passengers.

You do know why planes follow the routes they do don't you ?


Do you think the solar plane followed the same routes as the airliners?

No, but do you actually know why aircraft tend to follow the same 'path' ?


Some crashes in the '50s.
Why do you think they do?
