🇺🇸 USAF — Project Blue Book
In December 1949, during a routine training mission near Newfoundland, an aircraft detected an unidentified object via radar. The object approached the plane at an estimated speed of 600 miles per hour. Although the radar registered the contact, no visual identification of the object was made. When the aircraft executed a 90-degree turn, the object disappeared from the radar screen after about two miles. The incident was documented by Air Force officers, who were unable to identify the nature of the object.
The report, classified at the time for national security reasons, was written by a high-ranking officer and sent to the Director of Intelligence. The text includes legal warnings prohibiting the disclosure of its contents to unauthorized persons. Despite the technological limitations of the era, radar played a key role in detecting this unidentified aerial phenomenon, the nature of which remains a mystery.
