Yuma ufo
Dozens of frightened witnesses dialed 911 to report a UFO sighting on Wednesday, after seeing strange lights in the sky over Yuma, Arizona.

Now it seems the lights may have been part of a military exercise conducted by the Marines.

Several videos of the incident, from various areas of the city, were posted to YouTube, all showing a very similar sight. Glowing lights in the night sky, some seeming to drop fireballs, and configured in a triangular formation.

The video added here seems to show an unidentified flying object with lights all around the hull. The man who made it sounds confused and frightened.

But, it seems it was all part of manuevers conducted as part of a training exercise by a Marine squad stationed at the local air station.

"We had our Harriers flying over Barry Goldwater range, which is close to where people were saying they saw something unusual," said Capt. Staci Reidinger.

Apparently, the Harriers dropped parachute flares over the area, much as would be done in a real combat situation. Fair enough.

But, would it be too much trouble to alert local citizens that they're not being invaded or seeing a UFO?

Seems the least they could do...

Here's the video:
