The guy doing the commentary seems to be blissfully ignorant of the basic laws of gravity. On one hand he says the astronauts are not actually in space and on the other he wonders why the microphone is floating about, he suggests (sarcastically i'm assuming) it may be full of Helium. Not the brightest torch in the shed.
I enjoyed watching it because he is so arsey , I have no idea what his beef is with the people or space travel but he hates everything.
Alf Stewart from Home & Away was my favourite. Lived his whole life is a constant state of simmering beel.
