The vehicle was simply an extension of their own bodies

Aquamarine Dreams: 
Ralph Ring and Otis T. Carr
Las Vegas, August 2006

Ralph Ring is a brilliant innovative technician who as a young man in the late 1950s and early 1960s worked closely with Otis T. Carr. With the aid of his small team, Carr, who was himself a protegé of the great inventor Nikola Tesla, built a number of flying disks, which worked.... prior to their experimentation being forcibly terminated by government agents.
In a dramatic experiment, Ring co-piloted a 45 foot disk a distance of ten miles, arriving at their destination instantaneously. Ring, now aged 71, tells his story –the first time it has been reported.

"You must always work with Mother Nature. Force is never necessary. The laws of the physical universe are really very simple."
"You are assuming that ET crafts are made with our technology...
Many years ago, we made that same mistake and it took us several years to correct the mistake and start fresh from the drawing board. Their technology is nothing similar to ours...
We started from scratch and learned their principles of dynamics, physics, etc... The ET craft was manufactured using ET technology. This craft was built many years before we developed flight. They used a different physics principle that we still don't fully understand... I've worked on this project for 12 years and I sometimes call myself dumb because I try to compare the craft with our technology.
Doing that is dumb, as all who have worked on the craft over the years have come to understand."
 • Los Alamos National Laboratories physicist, quoted in Exempt from Disclosure, by Robert Collins.

"The pilots... knew they were going very fast, but it was so fast that they saw things stand still in time... At first our pilots could not interface with the craft. The Alien Life Form corrected the problem with three fingers on the globe panel. Then the wave formed and the craft began to cooperate and generate lift..."
 • James Jesus Angleton (CIA), quoted in Exempt from Disclosure, by Robert Collins
-- "The vehicle was simply an extension of their own bodies because it was tied into their neurological systems…"
 • Col. Philip J. Corso, The Day After Roswell

"My flying machine will have neither wings nor propellers. You might see it on the ground and you would never guess that it was a flying machine. Yet it will be able to move at will through the air in any direction with perfect safety."
 • Nikola Tesla, interviewed in The New York Herald Tribune, October 15, 1911
