Video here:
Language warning.
Any aircraft flown as seen in that video is much closer to biting it's pilot. In my opinion, this is entirely a training, and pilot discipline issue. The amphibian/water capabilities of such an aircraft lure the unwary pilot into "playing" over the water, thinking they are more safe. Take it from me, airplane collisions with water are nasty!
P.S. credit where credit is due, PPRuNe member Astrosfan had attempted unsuccessfully to post this video, and I had not noticed this, so I don't take credit for posting it first!
