Just quickly. I also agree with the above points.
However, in response to their comments re: the sunglasses.
I don't think they are actually sunglasses, I suspect they are prescription glasses that change their opacity / sun-filtering dependant on the light.
E.g. In indoor light they would appear to be wearing normal glasses. Outside on a sunny day it would look like they are wearing sunglasses. On a cloudy overcast day, it would look like normal glasses however in a rocket slowly approaching as well as looking directly at the sun, the glasses would be quite black.
