“He and his passenger donned life jackets…” They should have been “donned” before they ever got into the plane. I always put on a PFD whether I intend on landing in the water or not in my Searey. It should be mandatory in any seaplane or amphib. I’ve noticed that in all the videos I’ve seen of the Icon that no one is wearing a PFD. A rather cavalier, and potentially deadly attitude in my opinion. Always expect the unexpected.
