The B-24 wingspan was too much to get a perfect dry landing, one wing would have been felling trees. Plus the low ground clearance of the B-24 doesn't adhere itself to reef landings. They did a pretty good job though Woody, the plane looks to be in one piece, they all walked away from it, or paddled away from it.
Great pictures indeed, the middle picture is taken from a PBY at a later date, 26 days later, plane already breaking apart.
Looking at Arno on Google Earth it's hard to tell exactly where this happened, much less whether anything of the B-24 remains, but it would be interesting to know. I'd be willing to bet that there is still wreckage there. Maybe someone with more time than I have can Google Earth the shoreline (it's a big atoll).
One thing that is quite apparent is that the reef morphology at Arno is quite different from either Gardner or Seringapatam. I don't see a smooth surface out near the reef edge. I doubt that the B-24 pilot had any thought of saving the airplane. I imagine that his primary concern was saving lives. He elected to land as close to shore as possible and he obviously did a great job.
The break-up of the airplane as shown in the middle photo is exactly what I would expect. It looks like waves striking the port-side vertical stabilizer have caused the empennage to fail at its weakest point - the waist gunner windows.
