A taste of space with world’s first disabled astronaut, John McFall
The European Space Agency’s first para-astronaut experiences weightlessness on a “vomit comet”. …
Then, as the plane gets ready to nosedive back down, there’s a moment when we become weightless for about 20 seconds. It’s not that gravity has vanished, we’re still bound by the laws of physics. Instead, we’re actually in freefall – as is the plane around us – but this reproduces zero-gravity conditions. The plane repeats this manoeuvre again and again.
