Pentagon UFO report: No aliens, but government transparency and desire for better data might bring science to the UFO world

  On June 25, 2021, the Pentagon released a much-anticipated report on UFOs to Congress. The military has rebranded unidentified flying objects as unidentified aerial phenomena –UAPs – in part to avoid the stigma that has been attached to claims of aliens visiting the Earth since the Roswell incident in 1947. The report presents no convincing evidence that alien spacecraft have been spotted, but some of the data defy easy interpretation.
