It’s horrific knowing that two people who weren’t involved in the flight sadly lost their lives while just relaxing on a beach, I would hate to have this on my conscience if I was PIC during this flight.
To some, normally non-aviators, it seems obvious that the flight crew screwed this up. But being an aviator especially one who prefers not to immediately speculate I know there is potentially more to this.
Putting a plane down on a crowded beach is a bad idea (proven here), also so is ditching where you and your student or passenger may drown if they cannot get out, because as we know planes like this like to flip upside down in the water.
I will add that my opinion would be to ditch that plane in the water if the beach was too crowded given the situation and what I know now about the incident, probably just what everyone else does.
