The Consolidated PBY Catalina was an American flying boat of the 1930s and 1940s produced by Consolidated Aircraft. It was one of the most widely used multi-role aircraft of World War II. PBYs served with every branch of the US military and in the air forces and navies of many other nations. In the United States Army Air Forces and later in the United States Air Force their designation was the OA-10, while Canadian-built PBYs were known as the Canso.

During World War II, PBYs were used in anti-submarine warfare, patrol bombing, convoy escorts, search and rescue missions (especially air-sea rescue), and cargo transport. The PBY was the most successful aircraft of its kind; no other flying boat was produced in greater numbers. The last active military PBYs were not retired from service until the 1980s. Even today, over 70 years after its first flight, the aircraft continues to fly as an airtanker in aerial firefighting operations all over the world. The initialism of "P.B.Y." was determined in accordance with the U.S. Navy aircraft designation system of 1922; PB representing "Patrol Bomber" and Y being the code used for the aircraft's manufacturer, Consolidated Aircraft.

The Douglas DC-3 was born of the intense competition for modern commercial aircraft that characterized the post-World War I era. It was the direct descendant of the DC-1, which first flew in 1933 as Douglas' initial response to a short supply of competitor, Boeing Aircraft's, landmark 10-passenger 247, the first, low-wing, all-metal airliner. With only one 12-passenger sample flying, and already a record-breaking success, the DC-1 was quickly made obsolete, replaced by an a more powerful version with greater seating capacity, the 14-passenger DC-2, of which 193 were built.

Some interesting info and pics, thanks for posting.

Good stuff!

Inspired by the performance of the Grumman Goose during WWII, the U.S. Navy solicited Grumman to design a significantly larger amphibian with longer range. In 1944, Grumman submitted and won approval of its design G-64, to be named "Albatross," with accommodation for a crew of four, and a cabin capacity of 10 passengers, stretchers, or 5,000 pounds of cargo, as circumstances dictated. In addition, there were pylons under the wing and outboard of the engines which made it possible to carry weapons or drop tanks for increased range. In addition, fuel could be carried in the fixed underwing floats.

The Douglas DC-6 is a piston-powered airliner and transport aircraft built by the Douglas Aircraft Company from 1946 to 1958. Originally intended as a military transport near the end of World War II, it was reworked after the war to compete with the Lockheed Constellation in the long-range commercial transport market. More than 700 were built and many still fly today in cargo, military and wildfire control roles. The DC-6 was known as the C-118 Liftmaster in United States Air Force service and as the R6D in United States Navy service prior to 1962 after which all U.S. Navy variants were also designated as the C-118.

Good stuff!
