I went skydiving once. It was wonderful. I found when I was up in the plane and hanging out the door that all my worries were alleviated and replaced with a rather comforting thought; “well loads of people have done this, and they’ve not died.”
But then again, I did have a parachute.
When Luke Aikins launched himself out of a plane from 25,000ft last weekend, he had no such comfort. In fact, he just became the first person to ever jump from a plane so high and land safely without a parachute.
