Balloons don't pulse and hover in dead air like that, so maybe rethink it.

That bit about the lights blinking out one by one like a switch, thats the part that gets me. Ive had almost the exact same thing happen out near the Mojave, and I learned pretty quick to bring a good pair of binoculars and a tripod if youre gonna sit out there at night. Phone cameras are useless for this, trust me. Next time, try recording with the video setting and keep your finger on the screen to lock the focus, it helps a little. Also, check the military base schedules, they do weird drone tests out of China Lake and Edwards that never show on flight apps. Im not saying its aliens, but Ive seen enough strange stuff out there to know its not all explainable either.

Damn, SAME! I fought with my windowsill for years thinking I was doing something wrong. Got a cheap grow light last winter and my echeveria finally stopped looking like a sad little Dr. Seuss plant. The color change alone was worth it, they actually look purple now instead of just green mush.
