Roseville UFO Mystery Solved

The lights were attached to an airplane that belongs to a Bay Area aerial advertising firm that was announcing the grand opening of a tire store.

"It was the craziest thing I've ever seen," said News10 reporter Angel Cardenas, who recorded a nine-second clip of video from Air10 while flying over a high school football game in Roseville.

The incident prompted a number of calls to News10 and a buzz on the Internet.

The owner of the advertising firm said the plane occasionally stirs UFO sighting reports.

"From a distance it looks unidentified, lights are blinking," said Jason Frost of American Air Lights in Concord. "You can't read the words unless you're in the target audience (below the plane)."

Frost said he welcomed the exposure from the Friday night aerial ad campaign.

"It's good for us," he said.
