Strange Lights near San Francisco Airport

Strange Lights near San Francisco Airport
Time: 7:10pm
Location: South San Francisco, California, USA

My brother called me about 2 strange lights hovering for so long and 1 light blinking that was moving erratically. The two strange lights were below the blinking light but I’m not sure it was captured because I zoomed in on the blinking light. 

The strange light was going in circles for a few minutes, like it was looking for something. It sounds like a helicopter, but it doesn’t move like one. It was so far away and above me in seconds. I don’t think it’s a recreational drone either due to how fast it was moving and the large area it covered so fast. It was like a giant insect in the sky moving so fast. This was near San Francisco Airport (SFO). 

The video was not long because I was not sure if I was able to capture the lights on screen or not. I tried zooming in 5x, and it was hard to say where the camera was looking at.
