Supposedly hit the wing on the water one of the early articles said.
If you want a GA parallel to this incident, go back a couple of Christmases ago to the low flying GA pilot who killed himself in front of his neighbour.
He never had a chance that man. Didn't matter how many times we collectively warned him, he still continued to do dumb things to the very end. He was even under investigation from CASA at the time for low flying events. Time and time again he was told, told off, warned, advised, yelled at, banned, instructed etc and he still kept on going, finding new airports to fly from, new clubs to join, new people to hang out with and buying new aircraft. Peer pressure did not work in this instance so I don't accept the old "someone should have said something to him," because it doesn't guarantee a result.
