Carson Sink Case was a famous UFO incident that occurred over
the Carson Sink in western Nevada in the
States on July 24, 1952.
The incident is considered especially
noteworthy among UFO sightings because of the competency and
reliability of the witnesses, two experienced command pilots of the
United States Air Force
this day the objects sighted remain unexplained.
The two pilots who witnessed the incident were Lieutenant Colonel
John L. McGinn and Lieutenant Colonel John R. Barton, both veteran
fliers with distinguished military careers. At the time, both men
were assigned to the
Pentagon with highly
classified assignments and were familiar with even the most secret
foreign and domestic aircraft designs.
morning the two pilots were at Hamilton
Field north of San Francisco.
They requisitioned a twin engine B-25
bomber for a cross-country flight.
off headed for Colorado with unlimited visibility and perfect flight
California, and Reno,
Nevada, the two officers entered the "Green 3" aerial
highway to Salt Lake
At 3:40 P.M. MST while at 11,000 feet (3300
m) over the Carson Sink area east of Reno, the two lieutenant
colonels spotted three aircraft ahead of them and to their right.
At first they assumed that the unknown aircraft were F-86
fighter jets, based on their movements, but
realized that aircraft were far too high in the air space.
Moreover, the aircraft were flying in a perfect "V" formation,
which was highly unusual for military jets.
When the B-25 drew closer to the aircraft, McGinn and Barton saw
that the aircraft were bright silver in color with a delta-wing
airfoil, but without tails or flight
canopies, which every known aircraft possessed. The only break in
sharply defined, clean upper surface of the triangular wing was a
definite ridge that ran from the nose to the tail.
Neither men had previously seen anything remotely resembling the
unknown craft. As the two pilots watched, the three unknown craft
made a left bank and flew quickly to within 400 to 800 yards
(meters) of their B-25, which was an uncomfortably short amount of
space in the air. The two men estimated the speed of the unknown
aircraft to be at the very least three times that of any
conventional jet known to them. After four seconds, the aircraft
sped away out of the vision of the pilots.
When McGinn and Barton landed in Colorado Springs, they contacted
Air Defense Command
and learned that no civilian or military aircraft had been anywhere
near the Carson Sink at the time of the incident. In particular,
all known delta-wing craft, then flown exclusively by the Navy
, hadn't been anywhere in the
vicinity. The nearest such craft, which were painted dark Navy
Blue, were known to be on the West Coast at the time.
The two men dismissed the suggestion that they had seen F-86 jets
, since they were intimately familiar
with the design of that craft. Air Defense Command relayed the
report to Project Blue Book
investigation was started into the incident, but the incident was
officially left as unexplained. However, it is possible that the
pilots spotted a test flight of the Northrop YB-49
, an experimental flying wing
aircraft that is a precursor to the B-2
Stealth Bomber. The YB-49 was operated out of Muroc Air
Force Base (now Edwards Air Force Base), near Carson Sink, in the
late 1940s and early 1950s.
