Astronomer who studied multiple UFO sightings in the 1940s through 1950s and debunked many as natural phenomenon while also advocating for further research into other unexplained events.
Lincoln LaPaz was an astronomer whose work influenced other scientists to take UFO reports seriously. Throughout the 1940s and 1950s, LaPaz researched numerous reportings of UFOs, including green fireballs that were seen in the skies over New Mexico and the southwestern United States. This investigation was conducted by the U.S. Air Force under the secret code name Project Twinkle. He determined that many sightings were able to be explained through either natural or human-created technologies. Even so, LaPaz asserted that there were cases he was unable to determine the origin and argued that they should be further investigated.
