I've been reflecting a little on this for a few days now after reading with interest others' thoughts.
It seems that the perception of risk in such an activity doesn't sit well with some, which of course is natural.
My thoughts (FWIW) are that this is what this chap needs to do to truly feel alive. It may seem outrageously risky to the lay person but to him I'd imagine the risk was both manageable and acceptable.
To draw a comparison, to some rock climbing without a rope (soloing) is a reckless act. But it's all relative. An experienced rock climber will normally only launch himself at a rock climb that is well within his grade and ability. Yes, the rock could fail in some way (and it has in many cases) and the climber could be seriously injured or killed, but they would tackle this in the same way that your average person would walk up a set of stairs - although they're aware there's a risk of a stumble or fall that could lead to injury, it is considered highly unlikely. If you drive each day, cross the road, or ride a push bike on a public highway you're probably exposing yourself to a higher level of risk, but I'd wager these are considered an acceptable part of a daily routine.
So back to the chap in question. I'd wager he'll have rehearsed this many many times before, and prepared both physically and mentally. He'll have known, beyond all reasonable doubt that he could hit his target. He'll most likely have tested the netting. Reckless? Perhaps, perhaps not. Did he feel alive and elated at completing his challenge? Most likely. Did he pull it off? Yes he did.
Fair play to him.
