A rapidly moving, boomerang-shaped unidentified flying object (enlarged above) seen and videotaped above New York's Long Island is still confounding researchers, months after it was spotted.

The only eyewitness in this case reported it to the Mutual UFO Network, which investigates international UFO sightings. The incident (designated as Case 64777) remains listed as an unknown.

On April 17, the witness -- whose name isn't revealed  -- was driving home around 10:30 p.m. in Port Jefferson, New York, and noticed an odd light in the sky.

"When I looked to my left, I noticed red and blue lights hovering. I stopped and watched for a little bit to see if it was just someone playing with a toy," the witness wrote in his report to MUFON. 

"Then the object went higher into the air and started to move pretty fast. I then took out my phone and started to record for as long as I could till my phone died."
