Carson Sink UFO incident

 The 7 July 1952 , Lieutenant Colonel John L. McGinn and Lieutenant Colonel John R. Barton took off from the land of Hamilton . They were flying a B-25 and should reach Colorado Springs weather in a clear and unobstructed. At 3:40 p.m., while flying over the area of Carson Sink ( Nevada ), they saw a formation of three aircraft ahead of them and slightly to the right. They thought at first it was three fighter F-86 , although the altitude seemed to them a little low for this type of device. By approaching training, McGinn and Barton had to reconsider their decision: they were three silver objects, triangular, without glass or drift. The only outward sign was a kind of bridge from the nose to the tail. After a few seconds of observation, the three objects veered to the left, crossed low to the cockpit of the B-25 (300 to 700 meters according to two witnesses) and disappeared from their field of vision at breakneck speed (speed estimated at over 3 000 km / h by the two witnesses). Once installed in Colorado Springs, two pilots contacted the headquarters of the Air Defence Command, which confirmed that no civil or military aircraft had been detected in their vicinity during the flight over Carson Sink.
The personality of the two witnesses (experts in aeronautics from the Pentagon and experienced pilots totaling several thousand hours) formally eliminates the thesis of a misunderstanding with equipment from civilian or military.
The Blue Book recorded the case and conducted its own investigation-cons: the flight plans of military and civilian throughout the U.S. and all programs of the weather balloon release 24 July 1952 were analyzed but nothing could match (even by far) the observation of two pilots.
The Project Blue Book closed the case under reference 1584 in the category "unknown" (unexplained cause).
