Northwest Orient Airlines Flight 1-11 ditched off Polillo Island in the Philippines, killing one person and injuring 44.

Northwest Orient Airlines Flight 1–11 was a Northwest Orient Airlines flight from New York City to Manila, with stopovers in Seattle, Anchorage, Tokyo, and Okinawa. On July 14, 1960, the Douglas DC-7C serving the flight ditched in the ocean 8 km (5.0 mi) northeast off Polillo Island, Quezon, Philippines. Of the 58 people on board, 57 survived with 44 suffering from minor injuries and one passenger losing her life.

In aviation, a water landing is, in the broadest sense, an aircraft landing on a body of water. Seaplanes, such as floatplanes and flying boats, land on water as a normal operation. Ditching is a controlled emergency landing on the water surface in an aircraft not designed for the purpose, and it is a very rare occurrence. Controlled flight into the surface and uncontrolled flight ending in a body of water are generally not considered water landings or ditching, but are considered accidents. Most times, ditching results in aircraft structural failure.

Polillo is an island in the northeastern region of the Philippine archipelago. It is the largest island and the namesake of the Polillo Islands. It is separated from Luzon Island by the Polillo Strait and forms the northern side of Lamon Bay.
