i was sitting on my balcony having a smoke the lights pulsating and flashing off maybe a drone until i kept watching it the light was beyond, but parallel with the sjc planes flight path to land, i was watching the planes like i do every night, when i seen a light in my immediate vision. i focused on that area for a few more seconds to see if i saw what i thought i saw and as the plane flew by, in the planes headlights i seen a black shadow move very fast toward the plane and then seen a light glow and flashed off again. it was much too high to be a street light and no indicator lights like a plane should in this area. the lights had no specific pattern either because i was counting for a pattern. when i finally realized this was not a plane or a drone i grabbed my new camera and started filming. i wasn't even sure if i caught anything on film but upon review and color enhancement i noticed way more than i seen with my naked eyes. i could only see one glowing light in the distance with my eyes but in the video i seen 3 different lights and the white glowing light. it happened only about a minute i ran upstairs to get my wife to come and watch and when i did it was gone. i probably wouldn't have believed it myself if i didn't get it on film because i feel like i am very familiar with airplane indicator lights, planes and drones. i couldn't figure this out so i almost questioned myself until i seen the footage.
