Unidentified Flying Threats

The American government has not investigated U.F.O. sightings since 1969, when the Air Force ended Project Blue Book, an effort to scientifically analyze all sightings to see if any posed a threat to national security. Britain and France, in contrast, continue to investigate U.F.O. sightings, because of concerns that some sightings might be attributable to foreign military aircraft breaching their airspace, or to foreign space-based systems of interest to the intelligence community.

Most of the incidents investigated in Britain have been easily explained as misidentifications of stars and planets, aircraft lights, satellites and meteors, but some cases have raised national security or air safety issues.

In addition, there have been several incidents of near misses between U.F.O.s and known aircraft — enough to prompt the Ministry of Defense and the British Civil Aviation Authority to advise pilots, if they encounter anything, “not to maneuver, other than to place the object astern, if possible.”

The United States is no less vulnerable than Britain and France to threats to security and air safety. The United States Air Force or the National Aeronautics and Space Administration should reopen investigations of U.F.O. phenomena. It would not imply that the country has suddenly started believing in little green men. It would simply recognize the possibility that radar alone cannot always tell us what’s out there.
