The two final prototypes never flew. [5][6] Four of this order were redesignated as service test vehicles, and an additional eight production aircraft were soon ordered as well. Aircraft carrier design and technology made the Sea Dart unnecessary. [10], In the 1950s, the US Navy considered the internal arrangements of a submarine aircraft carrier that could carry three of these aircraft. Inattention to detail can lead to accidents. [11], The aircraft was built in Convair's San Diego facility at Lindbergh Field and was taken to San Diego Bay for testing in December 1952.

Reminiscent of the World War I German Fokker D.VII fighter, the elephant ear Travel Air 2000 gained a nickname as the Wichita Fokker. The second aircraft was lost during a low-level flight at about 575 mph over San Diego Bay on 4 November 1954. [15], Even before that, the Navy had been losing interest (problems with supersonic fighters on carrier decks having been overcome) and the crash relegated the Sea Dart program to experimental status. Convair amalgamated hydro skis, a delta wing, and two turbojets into a floating fighter that could get up on extendable skis and take off from a bobbing start on the ocean’s surface. Sorry, your blog cannot share posts by email. The skis were not extended until the aircraft reached about 10 miles (16 km) per hour during its takeoff run. The principals for improving gas mileage in an aircraft are optimizing engine operation, minimizing weight, reducing aerodynamic drag, and improving operation parameters. Oil pans and drain plugs are often "perfectly" located so that it is almost impossible to get to them without burning your hands, as well as spilling oil everywhere. The Saunders-Roe company of the United Kingdom, which had already built an experimental flying boat jet fighter, first flying in 1947 the SR.A/1, tendered a design for a ski-equipped fighter, but little came of it. Multigrade vs. single grade oil: Which is better for your engine? General Aviation News reserves the right to delete snarky, offensive or off-topic comments. [12], The second prototype was canceled, so the first service test aircraft was built and flown.

Ask Paul: Can I permanently remove the vacuum pump? [12], The underpowered engines made the fighter sluggish, and the hydro-skis were not as successful as hoped; they created violent vibration during takeoff and landing, despite the shock-absorbing oleo legs they were extended on. If I am not flying a stable approach to final — and I now know what that looks and feels like — I automatically go-around. The four surviving planes were retired in 1957, but some were kept in reserve until 1962. [8][7], The prototype was fitted with an experimental single ski, which proved more successful than the twin-ski design of the second service test aircraft. [4] On 14 January 1953, with E. D. "Sam" Shannon at the controls, the aircraft inadvertently made its first short flight during what was supposed to be a fast taxi run; its official maiden flight was on 9 April. On 4 November 1954, Sea Dart BuNo 135762disintegrated in midair over San Diego Bay during a demonstration for naval officials and the press, killing Convair test pilot Charles E. Richbourg when he inadvertently exceeded the airframe's limitations. Probable cause: The pilot's failure to attain a sufficient climb rate during initial climb in high-density altitude conditions with the airplane near its forward center of gravity and maximum gross weight limits, which resulted in an impact with trees. Now he devotes his energies to coverage for GAN as well as the Airailimages YouTube Channel. Hydro skis leveraged that phenomenon into flat plates that could keep a moving aircraft skimming on top of the water. The iPad app "completely reinvents the way flight training products work," says CFI Jason Miller.
