The PB2Y Coronado is a large flying boat patrol bomber designed by Consolidated Aircraft, and used by the US Navy during World War II in bombing, antisubmarine, and transport roles. Obsolete by the end of the war, Coronados were quickly taken out of service. Only one known example remains, at the National Naval Aviation Museum at Naval Air Station Pensacola, Florida.

After deliveries of the PBY Catalina, also a Consolidated aircraft, began in 1935, the United States Navy began planning for the next generation of patrol bombers. Orders for two prototypes, the XPB2Y-1 and the Sikorsky XPBS-1, were placed in 1936; the prototype Coronado first flew in December 1937.
After trials with the XPB2Y-1 prototype revealed some stability issues, the design was finalized as the PB2Y-2, with a large cantilever wing, twin tail with very marked dihedral, and four Pratt & Whitney R-1830 radial engines. The two inner engines were fitted with four-bladed reversible pitch propellers; the outer engines had standard three-bladed feathering props. Like the PBY Catalina before it, the PB2Y's wingtip floats retracted to reduce drag and increase range, with the floats' buoyant hulls acting as the wingtips when retracted. The price of the PB2Y-2 was US$300,000, or approximately three times that of the PBY Catalina.
Development continued throughout the war. The PB2Y-3, featuring self-sealing fuel tanks and additional armor, entered service just after the attack on Pearl Harbor and formed most of the early-war Coronado fleet. The prototype XPB2Y-4 was powered by four Wright R-2600 radials and offered improved performance, but the increases were not enough to justify a full fleet update. However, most PB2Y-3 models were converted to the PB2Y-5 standard, with the R-1830 engines replaced with single-stage R-1830-92 models. As most existing PB2Y-3s were used as transports, flying low to avoid combat, removing the excess weight of unneeded superchargers allowed an increased payload without harming low-altitude performance.
Coronados served in combat in the Pacific with the United States Navy, in both bombing and antisubmarine roles. PB2Y-5 Coronados carried out four bombing raids on Wake Island between 30 January and 9 February 1944. However, most served as transport and hospital aircraft. The British Royal Air Force Coastal Command had hoped to use the Coronado as a maritime patrol bomber, as it already used the PBY Catalina. However, the range of the Coronado (1,070 miles) compared poorly with the Catalina (2,520 mi), and the Short Sunderland (1,780 mi). Consequently, the Coronados supplied to the RAF under Lend-Lease were outfitted purely as transports, serving with RAF Transport Command. The 10 aircraft were used for transatlantic flights, staging through the RAF base at Darrell's Island, Bermuda, and Puerto Rico, though the aircraft were used to deliver vital cargo and equipment in a transportation network that stretched down both sides of the Atlantic, from Newfoundland, to Brazil, and to Nigeria, and other parts of Africa. After the war ended five of the RAF aircraft were scrapped, one was already lost in collision with a Martin PBM Mariner and the last four were scuttled off the coast of Bermuda in 1946.
Coronados served as a major component in the Naval Air Transport Service (NATS) during World War II in the Pacific theater. Most had originally been acquired as combat patrol aircraft, but the limitations noted above quickly relegated them to transport service in the American naval air fleet also. By the end of World War II, the Coronado was outmoded as both a bomber and a transport, and virtually all of them were quickly scrapped by the summer of 1946, being melted down to aluminum ingots and sold as metal scrap, or used as targets for fighter gunnery practice.

William Bethel Thompson (born 28 December 1906) was an Australian racing driver. From Summer Hill, Sydney, he was active in motor sport from 1928 to 1936. His competition cars included various Bugattis, a Riley Brooklands and an MG K3. Although his career was not taken to the international level, he met with considerable successful in Australia, winning the Australian Grand Prix three times.
Thompson died as a result of an aircraft accident on 12 February 1945 in the Marshall Islands, Pacific Ocean. At the time of the accident Thompson was serving in the Royal Australian Air Force and was travelling as an unauthorised passenger in a Consolidated PB2Y Coronado of the United States Navy.Blohm
Blohm is a surname. Notable people with the surname include:
Hans Blohm C.M. (born 1927), photographer and author
Linn Blohm (born 1992), Swedish handball player for IK Sävehof and the Swedish national team
Robert Blohm (born 1948), American and Canadian investment banker, economist and statistician, professor in China's Central University of Finance and Economics
Tom Blohm (1920–2000), Norwegian football playerConsolidated Aircraft
The Consolidated Aircraft Corporation was founded in 1923 by Reuben H. Fleet in Buffalo, New York, the result of the Gallaudet Aircraft Company's liquidation and Fleet's purchase of designs from the Dayton-Wright Company as the subsidiary was being closed by its parent corporation, General Motors. Consolidated became famous, during the 1920s and 1930s, for its line of flying boats. The most successful of the Consolidated patrol boats was the PBY Catalina, which was produced throughout World War II and used extensively by the Allies. Equally famous was the B-24 Liberator, a heavy bomber which, like the Catalina, saw action in both the Pacific and European theaters.
In 1943, Consolidated merged with Vultee Aircraft to form Consolidated-Vultee Aircraft, later known as Convair.Kawanishi H8K
The Kawanishi H8K (二式飛行艇, Nishiki Hikōtei, Type 2 Flying Boat. Commonly called as 二式大型飛行艇 Nishiki Ōgata Hikōtei, 二式大艇 Nishiki Daitei or Nishiki Taitei, Type 2 Large-sized Flying Boat) is a flying boat used by the Imperial Japanese Navy Air Service during World War II for maritime patrol duties. The Allied reporting name for the type was "Emily".
The Kawanishi H8K was a large, four-engine aircraft designed for long range and extended endurance on patrols or bombing missions typically flown alone over the ocean. The prototype first flew in January 1941 and H8K1s made their first combat sortie in March 1942. The robust H8K2 "Emily" flying boat was also fitted with powerful defensive armament, which Allied pilots had substantial respect for wherever this aircraft was encountered in the Pacific theater. The H8K was called by aircraft historian René Francillon "the most outstanding water-based combat aircraft of the Second World War."List of United States bomber aircraft

The Naval Air Transport Service or NATS, was a branch of the United States Navy from 1941 to 1948. At its height during World War II, NATS's totaled four wings of 18 squadrons that operated 540 aircraft with 26,000 personnel assigned.Short Shetland
The Short Shetland was a British high-speed, long-range, four-engined flying boat built by Short Brothers at Rochester, Kent for use in the Second World War. It was designed to meet an Air Ministry requirement (defined in Specification R.14/40) for a very-long range reconnaissance flying boat. The design used the company's experience with large scale production of the Short Sunderland. The end of World War II prevented the Shetland from entering production; it was the first aircraft designed with a 110 volt electrical system.Thomas F. Connolly
Thomas Francis Connolly Jr. (October 24, 1909 – May 24, 1996) was an admiral in the United States Navy, gymnast and Olympic medalist in the 1932 Summer Olympics.
Connolly served in Navy for 38 years. Over his career he served in World War II, oversaw the development of a program that later evolved into the United States Naval Test Pilot School, commanded two aircraft carriers, and served as Deputy Chief of Naval Operations for Air Warfare, retiring from that post in 1971.
Connolly was instrumental in the development of the Grumman F-14 Tomcat. The plane was named in his honor and for Thomas Hinman Moorer, then Chief of Naval Operations.USS Grand Forks (PF-11)

VH-1 (Rescue Squadron 1) was one of six dedicated (VH) Rescue Squadrons of the U.S. Navy during WWII. A more comprehensive write-up on the VH squadrons can be found in the history of Rescue Squadron 3 (VH-3), which was the US Navy's most active VH squadron. VH-1 made 19 direct rescues via open sea landings. It also assisted in the rescue of (at least) another 119 air crewman by locating them and directing surface vessels to effect the rescue. VH-1 was established on 1 February 1944 and disestablished in April 1946. The squadron employed the Consolidated PB2Y Coronado and the Martin PBM Mariner during its operations.
