someone's in trouble, or an unfortunate collusion of break-downs ?

Looks like they have it dragged back up onto the beach.
Some pictures look like the fuselage is broken on the port side, but no indication of that on starboard.
That runway looks like it runs right into the ocean.

I don't think it moved at all; it couldn't have gone very far in the water in the first place, especially with landing gear down. It's possible that the plane is pivoting a bit since it looks like the plane is slightly nose up, so the front gear might not actually be touching bottom.

This looks like the southwest end of the main runway which would have supported seaplanes to taxi into and out of the water. An easy ramp to roll down if you overshot the runway, with probably very shallow water. I don't know if there are still seaplanes operated there, but was heavily used for that during WWII.

Well... it's a Poseidon. So it is just meeting its destiny.

Main gear might have collapsed on striking the water and mud bottom underneath. That would also explain the nose-up tilt.
 
I presume the airplane was salvage in one piece by this method to prevent fluid spills.
 
The claim is that it remains intact. I'm sure there must be some damage to the fuselage but it was stated that no fuel leaked from the plane.

They're trying to sell the P8's to the Canadian government.
Perhaps this is just another "multirole" demonstration.
Too bad it didn't survive this mishap - Boeing could have charged us twice as much for a maritime patrol and reconnaissance aircraft AND submarine.
 
The P-8 is back ashore... they used inflatable rollers and winches and maybe a floating barge. It was 'floated'... then hauled it to the shore... then rolled onto-ashore [end of RW].

There are videos of ships being-launched and beached with many of these 'inflatable rollers' under the hull.

The airframe doesn't 'look bad'... but I have a bad feeling the engine pylons look bent-up... and tropical seawater immersion is as bad as it gets. OK, MAYBE wet volcanic ash is worse...

Poseidon Removed, Coral Damaged
Damage Not as Bad As Feared, Thanks to Aircraft's Buoyancy
A $1.5 million salvage endeavor finally removed the P-8 Poseidon that sat in Hawaii's Kaneohe bay for weeks, allowing investigators to evaluate the extent of natural damage caused by the runway overshoot.

The Navy had previously purged all the fuel from the Poseidon, hoping to prevent any hazardous contamination of the delicate ecology of the bay. In order to remove the plane, the Navy placed a series of inflatables underneath to lift and roll it straight up, removing its landing gear straight upwards in the hopes of minimizing coral damage. The ecosystem is a highlight of the Hawaiian tourist industry, and damage is extremely slow to repair.
Rear Admiral Kevin Lenox said that their studies in the surrounding water showed no indication of an aircraft spill, reducing the overall outlay from the Navy and allowing locals to breathe just a bit easier. The aircraft was shown to be resting its gear on coral beds, but the majority of it remained floating above the water. Kim Fuller, an aquatic biologist with the Hawaii Department of Land and Natural Resources, said divers are working to quantify the extent of the damage with their own surveys. They followed along the aircraft's path of travel with a series of dives, and feel they've largely seen the worst of it. They found that the primary impact area showed damage by the "anchors of containment booms", as well as overturned and scraped coral bodies.
No word yet on exactly what more the Navy will have to do in order to see the incident through, but it will likely be costly, as most of its Hawaiian accidents tend to be.
