Flying Saucer. Lots of UFO reports mid-Seventies, and this is my take on those reports. Now that they are coming back as UAP reports, it's time for a little fun.
Fantasy: the yellow beaded stalk for telemetry; the two brass and black thingys radiate Higgg's Bosons resulting from matter / anti-matter annihilation. The tail colors - just because and that's what sone folks claimed they saw.
Just for kicks: two triple banks of flashing red LEDs. A fuel tank that produces many false stops and re-starts before allowing a landing.
Reality: Enya .090 on 42 feet of lines, 7x2 prop. It's good for circles and not much else stunt-wise.
