UFO report: US 'has no explanation' for sightings of 143 mystery objects

The US government has said it has no explanation for dozens of unidentified flying objects seen by military pilots. A Pentagon report released on Friday says of 144 reports made about the phenomena since 2004, all but one remain unexplained. It does not rule out the possibility that the objects are extraterrestrial.

US Congress demanded the report after the US military reported numerous instance of objects seen moving erratically in the sky. The Pentagon then established the Unidentified Aerial Phenomena Task Force last August to look into the reports.

The group's job was to "detect, analyse and catalogue" these events, as well as to "gain insight" into the "nature and origins" of UFOs. The report does not mention aliens or even vaguely hint at an extraterrestrial explanation for the reported sightings, but makes clear that much of the phenomena may be beyond the existing means the government has to identify such objects.
