The Defense Department has confirmed that leaked photos and video of "unidentified aerial phenomena" taken in 2019 are indeed legitimate images of unexplained objects.
Photos and videos of triangle-shaped objects blinking and moving through the clouds were taken by Navy personnel, Pentagon spokeswoman Sue Gough said in a statement to CNN. She also confirmed that photos of three unidentified flying objects -- one "sphere" shaped, another "acorn" shaped and one characterized as a "metallic blimp" -- were also taken by Navy personnel.
