Is the truth really out there? It’s an age-old question, with reports of UFOs going back decades. We looked back at actual UFO and alien investigations by the U.S. and other countries.
Projects Sign and Grudge – 1948-1951
Many accounts of UFOs in the United States describe something called the Roswell incident. Local accounts of a “flying saucer” landing near Roswell, New Mexico, in 1947 led to many alien conspiracy theories, but the U.S. Air Force denied an E.T. connection. In the 1990s, the Air Force said the object was actually a balloon that was searching for Soviet Union nuclear test signals under Project Mogul.
However, the incident did prompt official U.S. investigations into unidentified flying objects in the next few years. A report published for the U.S. Air Force’s Project Sign (1948-1949) stated that the things people saw were “real” but that at least “some of the incidents may be caused by natural phenomena” and others may be related to domestic or foreign aircraft. The Air Force’s Project Grudge, which issued a report in 1949 prior to its shutdown in 1951, continued the investigation but found no conclusive evidence of UFOs.
