>>64035284 (OP)they've made shit that looks just like it, some even having proposed names that were suppose to be made up bullshit
donuts-on-a-chain is a real thing, my father saw the trails, they sound it made was a deep "gonk-gonk-gonk", didn't see the craft though
that would have been towards edwards at the time. honestly though i don't think the aurora is the same thing as the donuts
i've seen the floating triangles before, made no sound, looked the same under night vision, flew very slowly, are about the size of a standard jet, emit purple mist, etc
i think theres a chance it might have been a plasma engine, you can make them at home so i assume some trillion dollar eggheads can make something better than what we know publicly
