An artist's conception of the Aurora aircraft (Janes conception, appearing in Advanced Tactical Fighters) Aurora is a rumored mid-1980s American reconnaissance aircraft. There is no substantial evidence that it was ever built or flown and it has been termed a myth. [1] [2] The U.S. government has consistently denied such an aircraft was ever built.
The Lockheed CP-140 Aurora is a maritime patrol aircraft operated by the Royal Canadian Air Force. The aircraft is based on the Lockheed P-3 Orion airframe, but mounts the electronics suite of the Lockheed S-3 Viking. "Aurora" refers to the Roman goddess of dawn who flies across the sky each morning ahead of the sun. [1]
Work on the Orion began in 2006, when the U.S. Army funded it as a hydrogen-fuelled “high-altitude, long-loiter” (HALL) UAV. Originally, it was conceived as a single-engine, hydrogen-fueled, high-altitude unmanned aircraft intended to carry a 400 lb (180 kg) payload to 65,000 ft (20,000 m) having a 7,000 lb (3,200 kg) gross weight; similar aircraft included the AeroVironment Global ...
In 2009, as Aurora developed small vertical take-off UAVs known as the Aurora Goldeneye, the third variant of this family, the GoldenEye-80, was first flown publicly at Association for Unmanned Vehicle Systems International's Unmanned Systems North America trade show. On 5 October 2017, Boeing announced that it would acquire Aurora Flight Sciences.

Airspeed is commonly given in knots (kn). Since 2010, the International Civil Aviation Organization (ICAO) recommends using kilometers per hour (km/h) for airspeed (and meters per second for wind speed on runways), but allows using the de facto standard of knots, and has no set date on when to stop.
A single-engined Cessna 150L's airspeed indicator indicating its V-speeds in knots. In aviation, V-speeds are standard terms used to define airspeeds important or useful to the operation of all aircraft. [1] These speeds are derived from data obtained by aircraft designers and manufacturers during flight testing for aircraft type-certification.
Aurora Flight Sciences embarked on the development of an experimental X-plane, as part of the DARPA's CRANE programme, in November 2020. Wind tunnel testing was also conducted in San Diego, California, in May 2022. DARPA allocated funds for the detailed engineering design of a full-scale X-plane in December 2022.
