Ocean County Sheriff Michael Mastronardy sent police's "industrial-grade" drone into the air after a local policeman saw about 50 UFOs "coming off ocean" in US' New Jersey. The mysterious, SUV-sized UFOs didn't give off heat and reportedly had wingspans measuring eight feet. Mastronardy said the UFOs "easily" evaded the police drone. Coast Guard officials had also reported seeing 13 UFOs.
