On August 5, 1941, AMM1 L. L. Stonerock was the pilot of Coast Guard aircraft V-126, a Douglas RD-4 Dolphin, during a routine patrol off the California coast. Skimming close to the ocean due to foggy conditions, the amphibian plane apparently struck a jutting rock and exploded off the Farallon Islands near San Francisco. Wreckage of the plane was found by a minesweeper sent to search for it when regular radio reports ceased to be received. Naval minesweepers found bits of wreckage near the jagged rocks of the island and made identification of the plane from a wing fragment.
