Between 1959 and 1972, the Space Nuclear Propulsion Office oversaw 23 reactor tests, all at the Nuclear Rocket Development Station at AEC's Nevada Test Site, in Jackass Flats, Nevada, about 160 km (100 miles) west of Las Vegas. The KIWI and Phoebus series, Peewee-1, and the Nuclear Furnace 1, all conducted by LASL on the Rover side of the program to prove concepts and test advanced ideas. Aerojet and Westinghouse tested their own series for use in the NERVA engine: NRX-A2 (NERVA Reactor Experiment), A3, EST (Engine System Test), A5, A6, and XE-Prime (Experimental Engine).

In the late 1960s and early 1970s, the Nixon Administration cut NASA and NERVA funding dramatically. Eventually the NERVA/Rover program lost its funding altogether, and was terminated on Jan. 5, 1973.

John Hutchison is a Canadian inventor known for his claims of inventions and discoveries of a variety of extraordinary phenomena, which other researchers - and often Hutchison himself - have been unable to duplicate.

All of us crackpots have that right! Now.
Galileo didn't have that "right"...and was forced to recind his ideas...but what if he had not been?

Since 400 AD, Chinese children have played with bamboo flying tops. This toy made its way to Europe and is depicted in a 1463 European painting.[5] Pao Phu Tau (???) was a 4th-century book in China reported to describe some of the ideas inherent to rotary wing aircraft:[6]
“ Someone asked the master about the principles of mounting to dangerous heights and traveling into the vast inane. The Master said, "Some have made flying cars with wood from the inner part of the jujube tree, using ox-leather [straps] fastened to returning blades so as to set the machine in motion."[7] ”

Leonardo da Vinci conceived a machine that could be described as an "aerial screw".[8] He wrote that he made small flying models [9] but could not stop the rotor from making the whole craft rotate. Later machines would more closely resemble the ancient bamboo flying top, with spinning wings rather than screws.

In July 1754, Mikhail Lomonosov showed the Russian Academy of Sciences a small coaxial rotor powered by a wound-up spring, intended to lift meteorological instruments.[9]

In 1783, Christian de Launoy, and his mechanic, Bienvenu, made a model pair of counter-rotating rotors (not coaxial) using turkey's flight feathers as rotor blades, and in 1784 demonstrated it to the French Academy of Sciences.[9]

In 1861, the word "helicopter" was coined by Gustave de Ponton d'Amécourt,[9] a French inventor who demonstrated a small steam-powered model.

From 1860 to 1880, many small helicopter models were designed and made.[9] These included Alphonse Pénaud's model coaxial rotors, powered by twisted rubber bands (1870). Enrico Forlanini's unmanned helicopter was powered by a steam engine. It was the first of its type that rose to a height of 13 meters, where it remained for some 20 seconds, after a vertical take-off from a park in Milan (1877). Emmanuel Dieuaide's design featured counter-rotating rotors and was steam-powered through a hose from a boiler on the ground (1877). Melikoff designed a "man carrier," but it was almost certainly not built (1877). Dandrieux's design had counter-rotating rotors and a 7.7-pound (3.5-kilogram) steam engine. It rose more than 40 feet (12 meters) and flew for 20 seconds (circa 1878).

In the 1880s, Thomas Edison experimented with small helicopter models in the USA. First he used a guncotton-powered engine, but it caused damage by explosions, and tests were ended. Next he used an electric motor. His tests showed that a large rotor with low blade area was needed.

Ján Bahýl, a Slovak inventor, developed a model helicopter powered by an internal combustion engine, that in 1901 reached a height of 0.5 meters. On 5 May 1905, his helicopter reached four meters in altitude and flew for over 1,500 meters.[10]
