Are the SpaceX boosters that Musk want to land going to orbit? No.
Is the extra fuel needed to make such a landing a big part of going to orbit? No.
The extra weight a enerby needed to land vertically has nothing to do with a 900 factor. Musk's tweet is thus equally disengenuous. It makes it sound like vertical landing a booster for a rocket going to orbit is tremendously harder than what BO did. It is not, it's the same ball park.
