The U.S. government is set to receive an unprecedented intelligence report next month on the mysterious sightings of UFOs. 

After years of public denial, the report will acknowledge that UFOs — which means unidentified flying objects — are not just a matter of science fiction and conspiracy theories. The U.S. government admits that there is something out there, and they want to know what it is.

Upon further study of the sightings, most are determined to be common aircraft, stars, fireballs or other easily explainable phenomena. But there are still dozens left unexplained.

Then, she says, they spotted an object in the sky shaped like a Tic-Tac.
