Re: They land back to earh requires an ungodly amount of fuel
Launching towards East from the West Coast is not possible for any launcher, as flight over populated area is prohibited. Any mishaps would be dangerous!
West Coast launches are performed generally towards directions in between South and West which enable polar orbiting flights and retrograde orbits. Flying to those orbits is not possible from the East Coast (Florida) because exactly the same reasons.
The SpaceX-assigned Landing Pad next to the launch pad at the west coast is currently occupied by a temporary building in where SpaceX is doing something that has not been revealed yet.
