To back up the ‘always learning’ comments:

A quote from an article on Canadian Lake Pilots in Pilot Magazine a few years ago:

The hunters loaded up the aircraft with their kit and the prodigious spoils of their hunting, they taxied up to the end of the lake and turned into wind, full throttle was applied, but the aircraft only just got clear of the water before crashing into the trees at the other end. As the pilot was sitting there, upside down in his straps he said: “Funny, exactly the same thing happened last year!”
