Mysterious Flying Lights Spotted Over U.S. City

( Two weeks ago, strange orange lights were spotted in the night sky from Tijuana to San Diego County.

The lights appeared around 9:00 pm PST on September 19 and remained visible for about a half hour. While the exact location of the lights was difficult to pin down, some witnesses said they appeared to be hovering over the Pacific.

The US Navy has a large presence in the area, and it was suggested the lights were military in origin.

According to local news outlet NBC San Diego, the US Coast Guard said the Air Force was conducting drills in the area. However, NBC San Diego did not hear back from the Air Force to get confirmation.
