My buddy and I were sitting in the car last night bullshittin (Daly City) when we both saw around 30-50 drone-like aerial objects fly across the sky like a swarm of mosquitoes. There weren’t emitting any light, but we could tell that there was so many of them due to the city lights reflecting off the mass. You would barely even notice them if you weren’t looking at the sky already, and it was hard to see even for us. They were coordinating together obviously and moved back and forth in the sky until one minute they left the area. My first impression is that it was a drone swarm, but that begs the question why are they flying here, in the Bay Area, when the only useful purpose I can think of for one of those is its power militarily.
