Grumman SA-16 Albatross
An improvement of the design of the Grumman Mallard, the Albatross was developed to land in open ocean situations to rescue downed pilots and other flight crew members. Its deep-V hull cross-section and substantial length enable it to land in the open sea. The Albatross was designed for optimal 4-foot seas, and could land in more severe conditions, but required JATO (jet-fuel assisted take off, or simply booster rockets) for takeoff in 8–10-foot seas or greater.
