[@mrsponkman]

This video was a documentary made in 1961 about those in the 1920s, so 51 years ago.

[@SSmith-fm9kg]

Many of these "attempts at flight", which were not included in this reel, except possibly the plane that flapped its wings up and down and the prop, attached to nothing, fell off, were come-ons for newsreel cameramen, created solely as a story to film. The guy with the flapping wings mounted to the bicycle, for instance. This type of camera news was typical of the day, to be shown as a lead-in prior to a motion picture in a theater. Television would not appear for another quarter century. I remember one of a little girl, probably about 7, billed as a sharp-shooter with a pistol. She would shoot at glass bottles on a stand, while aiming with a mirror. Turns out the cameraman had it rigged with mousetrap mechanisms, and he would pull a string off-camera, causing the trap to break the bottle as the little girl fired, but at a distance, you couldn't see the mechanism. Still, this stuff is good for chuckles...

I remember watching an extended version of this at the Stafford air and space Museum. I remember one of them was some sort of plane with like five or six wings stacked on top of each other. it never left the ground.

[@Pavel_Poluian]

It all started with the vibrating umbrella-orthopter "Sky Car" by James Pitts, then the umbrella was closed with a dome and devices appeared according to the scheme of conventional electromagnetic vibrating speakers (membrane + inductance) - fragments of the membrane were found by a farmer in Roswell. Then they created piezoelectric motors or with small dischargers on the surface (they glowed all over the body due to air ionization), and now these are aircraft with plasma propulsion panels (because they are angular - that is, with flat surfaces). Thousands of discharge cells are packed tightly in the motor panels - they shoot plasma streams (railgun architecture - coaxial electrodes). The ionized air of the spark discharge is accelerated in the railgun cell by the Lorentz force to enormous speeds - a kind of ramjet engine is obtained. Just imagine! - tens of thousands of small ramjet engines assembled in a panel and firing plasma synchronously with a huge frequency (hundreds of kilohertz). Plasma jets form toroidal vortices of air - this air cushion creates lift and acceleration force. In my article "UFO - it's made in the USA" and in the books "UFO Hunting" and "UFO Elimination" all this is described in detail. The technology is quite mundane - it is known in the smallest details due to information leaks. For example, air ionization in coaxial railgun cells is created with the help of radiation (radioactive polonium is introduced into the metal). Devices of this type were used all 50-60-70-80 for secret missions (they took off, as a rule, from special submarines). With the fall of the USSR, their use by the United States was practically curtailed (in the novel "Little Green Men" by Christopher Buckley, a speechwriter for Bush Sr., a scene is described where the US president decides to curtail the project with "flying saucers"). The curtailment of the project can be recorded by the drop in magnesium consumption in the United States, since such fuel was used in fuel cells (magnesium tapes burned in forced galvanic batteries), this is 2007-2008. However, the development of the technology continued later in the Russian Federation and China (the technology was restored by reverse engineering methods for downed devices). Secrecy, however, remained, and there was no civilian use, because the technology is not suitable for this - harmful microwave from pulsed plasma engines (harm to pilots and the impact on electrical appliances inside and along the flight line). The payload is low (but one nuclear charge will pull.) There is no radio communication - unmanned vehicles can fly and maneuver only according to the program. Previously, there was a narrow application profile - rare spy missions (so that pilots do not receive a lot of radiation). Reconnaissance aircraft of this type were often observed at military bases, missile launch pads and airfields. They were even seen by peaceful explorers in the taiga, where glades were laid for seismic exploration - UFOs flew there to check whether military construction was underway (I myself heard stories about it))). I think this technology will be declassified soon, and cargo airships with flickering round plasma panels on the hull surface will appear in the Arctic sky.
