A California witness driving southbound along Harbor Blvd. toward the 405 Freeway near the Santa Ana and Costa Mesa area on April 5, 2012, reports watching a diamond-shaped object hovering in the sky that emitted a humming noise, according to testimony from the Mutual UFO Network (MUFON) witness reporting database.

"At this time I saw what appeared to be a diamond-shaped vehicle in the eastern sky approximately one mile from my location," the witness stated. "While I was driving I noticed the vehicle hovering, so I thought it was a helicopter, but then it did not have the aviation lights. Also, it was much too big to be a helicopter."

The witness eventually pulled over for a better look.

"At this time the vehicle tilted on its side and then I was able to see it was in the shape of a diamond, or actually two diamonds connected in the middle. At first I thought it was a hoax, but this vehicle was much too sophisticated to be a toy and very large. It made a humming noise that I could hear from approximately a mile away. Several people in the parking lot became spectators with me as we all watched in awe."
