I've flown into this airport on UA for a dive holiday. Can confirm that on approach if seated on the lagoon side it feels like you're coming in for a water landing regardless!

I was pleasantly surprised by the ABC and SMH coverage of this incident; referring to a water landing rather than a crash into the sea. (Edit: ok ABC have since updated the story and now include the term crash. Other media outlets are using the term with gay abandon).
Very happy for the passengers and crew all evacuated safely. Looks like the locals in their boats were out there very quickly and the plane was only a short distance away. One of the passengers reportedly said he just thought they'd landed hard until there was a hole in the side of the plane and water started coming in.
I heard in another report that the plane has now sunk. I reckon there's probably some very expensive dive gear wet in the hold and some relieved but disappointed divers in one of the best dive destinations in the world without their gear.
