National Research Associates, Inc
In 1958 Melville W. Beardsley founded National Research Associates company. NRA developed and tested over 30 air cushion vehicles, with the Air Gem Air cushion vehicle produced as their first product. NRA also sold Disney's Flying Saucers attraction under license. The Company went out of business in 1963. National Research Associates, Inc was a United States of America aircraft manufacturer... NRA Developed Air Cushion Vehicles for the Army and Marines. In 1959 The Marine Corps signed a $40,000 contract for a 14x3 ft demonstration vehicle. NRA's development facilities were located in College Park, Maryland and Laurel, Maryland. After moving on from NRA, Beardsley spent several years contesting who had the rights to the patent of the Hovercraft concept with Christopher Cockerell Sir Christopher Sydney Cockerell CBE RDI FRS (4 June 1910 – 1 June 1999) was an English engineer, best known as the inventor of the hovercraft.

Flying Saucers (attraction)
Flying Saucers was an amusement ride at Disneyland in Anaheim, California from 1961 to 1966. The ride was manufactured by Arrow Development and National Research Associates, Inc. Guests rode on personal flying saucers on a cushion of air, similar to an air hockey game, which played in a way similar to bumper cars with guests ramming each other with their saucers. As the ride began, the saucers would be subject to a high volume of low-pressure air directed underneath the saucers by means of a grid of circular valves from a plenum chamber below the field on which they operated. As the saucers moved about the field, the valves would open and close in response to their proximity. As guests shifted their weight in any direction by leaning, saucer movement would respond by means of an air jet derived from the increased pressure in the saucer's plenum. If weight was centered, the saucer would begin to "hop" up and down as the air randomly escaped around the plenum. All that was requi ...

Laurel, Maryland
Laurel is a city in Maryland, United States, located midway between Washington and Baltimore on the banks of the Patuxent River. While the city limits are entirely in northern Prince George's County, outlying developments extend into Anne Arundel, Montgomery and Howard counties. Founded as a mill town in the early 19th century, Laurel expanded local industry and was later able to become an early commuter town for Washington and Baltimore workers following the arrival of the Baltimore and Ohio Railroad in 1835. Largely residential today, the city maintains a historic district centered on its Main Street, highlighting its industrial past. The Department of Defense is a prominent presence in the Laurel area today, with the Fort Meade Army base, the NSA and Johns Hopkins' Applied Physics Laboratory all located nearby. Laurel Park, a thoroughbred horse racetrack, is located just outside the city limits. History Natural history Many dinosaur fossils from the Cretaceous Era ar ...

Aerospace Companies Of The United States
Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications. Aerospace engineering consists of aeronautics and astronautics. Aerospace organizations research, design, manufacture, operate, or maintain both aircraft and spacecraft. The beginning of space and the ending of the air is considered as 100 km (62 mi) above the ground according to the physical explanation that the air pressure is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. Overview In most industrial countries, the aerospace industry is a cooperation of the public and private sectors. For example, several states have a civilian space program funded by the government, such as NASA, National Aeronautics and Space Administration in the United States, European Space Agency in Europe, the Canadian Space Agency in Canada, Indian Space Re ...
