I was on my computer all day. then i went outside to check and see what was above my room. at first it looked like a glowing boomerang shape or parachute with no person attached. so i went back to the room to grab the camera, it only took 1 minute from the original sighting for it to change direction and ascend without me seeing it. when i got back out to backyard to film it, it had already ascended to approximately 10,000 ft above ground. watched it for a few minutes. at the time when i was filming the object it was an orb like. and followed it to my neighbor's front lawn and it was already too far away to the east. at 6 pm i was already back in my computer and heard 3 sonic booms. the next afternoon at 5 pm, after work i saw 3 f-16s taking off from mcas miramar heading north to go back to their home base. at the airshow i asked where the f-16s were coming from, the marine told me that it was mcas yuma that called for f-16s to intercept this ufo. so they came back to miramar only to file report, refuel and rest before heading home.
