UFOlogists have tried to explain the timeline in various ways. The larger type has been documented for thousands of years. The smaller discs were first publicly described in WW2, with both sides seeing flocks of discs and each side blaming the other. There was a postwar ‘pulse’ of the bigger type in ’47, then another big pulse around ’52 to ’54, then ’65 to ’67. Then the sightings pretty much stopped.
My first try at explaining the timeline was uninformed. I assumed they were our experimental spy tech, which became unnecessary after ’67 because surveillance satellites with digital cameras took over the job.
After reading more of the ancient history I had to abandon that notion, and now I’m imagining the devices as charge-based life forms. The smaller discs are the pets (birds or dogs) of the winged humanoids. The larger aircraft are horses carrying the winged humanoids.
Some of my first assumption was unquestionably true. The government was taking advantage of the public attention, playing both sides as always. The Ground Observer Corps was definitely meant to check the stealthiness of our new tech; and there’s some evidence that our new tech was trying to imitate the old mysterious tech. But our tech wasn’t the ONLY story.
Thinking about the charge vortex….. What development by the large wingless humanoids would be MOST THREATENING to a creature made of circling charge?
The magnetron creates an internal charge vortex, which would specifically mess up the living charge vortices. The most common use of the magnetron is diathermy (microwave ovens) which directly competes with the main defense weapon of the charge critters.
The history of the magnetron fits the crucial dates neatly:
Invented in the ’30s for radar but not used much because its oscillations weren’t steady enough. Radar needs precise freq and phase, so radar soon adopted the klystron instead.
In 1947, Raytheon built the “Radarange”, the first commercially available microwave oven. An early Radarange was installed (and remains) in the galley of the nuclear-powered passenger/cargo ship NS Savannah. An early commercial model introduced in 1954 consumed 1.6 kilowatts and sold for US$2,000 to US$3,000. Raytheon licensed its technology to Tappan in 1952. Under contract to Whirlpool, Westinghouse, and other major appliance manufacturers looking to add matching microwave ovens to their conventional oven line, Tappan produced several variations of their built-in model from roughly 1955 to 1960. Due to maintenance and cost, sales were limited.
Japan’s Sharp Corporation began manufacturing microwave ovens in 1961. Between 1964 and 1966, Sharp introduced the first microwave oven with a turntable, an alternative means to promote more even heating of food. In 1965, Raytheon, looking to expand their Radarange technology into the home market, acquired Amana to provide more manufacturing capability. In 1967, they introduced the first popular home model, the countertop Radarange. Unlike the Sharp models, a motor driven mode stirrer in the top of the oven cavity rotated allowing the food to remain stationary.
Development of magnetrons for diathermy (heating food) started in ’47, so the charge critters started investigating the threat. Major milestones in ’52, ’54, and ’64, inspiring more investigation and perhaps attempts to halt the deadly peril. Widespread adoption in ’67. Time to retire from the field. The large wingless humanoids are purely toxic.

The discs were also allergic to smaller charge circulators like alternators and generators. If we can believe the stories, the discs had a non-destructive way of shutting down generators. (Applying a counter-rotating field???) Cars stalled in the presence of the discs, then started up again later. Battery-powered flashlights didn’t shut off. I can’t try to match a timeline for dynamos, since they were pretty much everywhere after 1890.
