Looking at the video from news7 chopper, if you look to the left of the aircraft and canopy, you can see an exact imprint of the nose, forward fuselage area in the mud - looks like flying left to right, high speed - ie not water landing, probably "showboating" and left wingtip caught something solid and hard, slammed into mud bank, and then slewed back to where it is resting, possibly with a full 360 on the way looking at the way the fin has wrapped itself around. When you look at all the videos on the ICON website, they have a full blown "showboating" mentality for trying to sell the "awesome" machine.
Im a position holder..... but not holding out much hope now to be honest!!
