I am guilty more than once of accepting a needless risk in a plane. So is this pilot. I've been working on smartening up as I get old - I want to be older, and insurable.
I see a very disproportionate risk to benefit in this kind of flying. If you're going to fly in a very risky way, at least have a good benefit to balance the risk.
And... it sets a poor example, and image for our industry. It make the public wary and suspicious of our responsibility, and lures fools into attempting it. I recall a silly fellow tried it in an English river a few years back, not putting any though into the fact that this is characteristically impossible in a tricycle aircraft.
If you're going to do this where you can't be seen, then you're probably too far from the help you may suddenly need very badly!
