🇺🇸 USAF — Project Blue Book
In 1950, a U.S. pilot reported seeing a dark object moving at high speed without making noise. The incident occurred near Santa Fe, New Mexico, at 4 a.m. The observer, an Air Force officer, described a craft that looked like an aircraft but disappeared quickly despite his attempt to follow it at over 620 mph. No photos were taken and no physical evidence was found, adding mystery to the case.
The object was dark or black and moved in a straight line. The pilot, experienced and reliable, couldn't precisely identify it. The Air Force concluded it was an aircraft, but other possibilities weren't ruled out. This report, classified for decades, shows how even the military recorded phenomena they couldn't easily explain.
