In the film, Drax's shuttles dock with a space station
The film of course.
Drax in the film is (like Musk) concerned about a catastrophe wiping out human civilization on Earth.
Besides I strongly doubt that Musk can pull off a Liverpudlian ascent if his life depended upon it.
What I am waiting for is Bill Hader of Saturday Night Live to pop on a Nehru jacket and announce what all those rockets are really for.
I can't shake the feeling he's been tweaking his Julian Assange, waiting for the right script.
