What we propose below is an excerpt of a documentary, aired in 1956 in the United States, entitled "Unidentified Flying Objects." The film was commissioned, they say, USAF (United States Air Force). So it would be the first and only (so far) documentary on UFOs, from military, aired in movie theaters. The film has never been translated into Italian. This piece analyzes the famous cases of "Great Falls, Montana" in 1950 and "Lights in training" of Tremonton year 1952. Analysis that said something very important. They were showing real video and real UFOs. Here's the video age, in their original language.
