YSD-8 handling the hulk of the wrecked experimental seaplane Hall XP2H-1 at NAS Coco Solo, 1935. The original caption for the photo reads: "Hull of Navy 'Mystery' Plane XP2H-1. She split her engine mounts and buckled the hull while trying full load takeoff. Being loaded aboard 'Mary Ann' for transfer to U.S.S. Wright [AV-1]. It was the largest plane the Navy had." This aircraft was the largest four-engine biplane the Navy procured; it traveled nonstop between Norfolk and Coco Solo (2,000 miles) in 25 hours and 15 minutes in January 1935. Most sources say the crash took place as the plane "attempted to alight on open water," disagreeing with the caption cited above. In any case, after the Hall's demise, the Navy concentrated on smaller two-engine monoplanes for its patrol squadrons, leading up to the PBY and beyond.
