1951: Lubbock Lights, Andrews AFB, an F-51 over Mankato and Deke Slayton's chase near Hastings.
1951: UFO|UAP & Entity Sightings, by Month, Yearly Hub
In 1951 the Air Force sent pilots, radar crews and interceptors after UFOs, and most of them came back empty-handed. On July 9, 1st Lt. George Kinmon Jr. watched a white oval object dive repeatedly at his F-51 over Georgia. On September 10, two officers in a T-33 chased a silver disc over the New Jersey coast while Fort Monmouth radar students tracked fast, hovering echoes. On September 23, six F-86 pilots in three flights failed to reach a silver object orbiting at 50,000 feet over March AFB. On November 24, an F-51 flight leader near Mankato, Minnesota watched a small white flying-wing shape pass 100 feet from his aircraft, and on December 12, a future astronaut named Deke Slayton lost an object he was chasing near Hastings, Minnesota.
Around those chases sit the Lubbock Lights, photographed by a Texas Tech freshman after three professors saw them; the Capital Airlines Flight 610 sighting at Andrews AFB; two unexplained December 7 cases at Oak Ridge and Sunbury; and a global run of close encounters, from a farmer near Veghenza, Italy to an innkeeper in Casteil, France paid in gold nuggets. This is the complete 1951 UFO sightings archive: twelve monthly indexes and an Unknown Date page, tracing a year in which the Air Force kept looking up and kept coming home with nothing to hold.

The Air Force That Kept Looking Up
Who Was Watching in 1951
The Fighter Pilots: Kinmon in Georgia, the T-33 crew over Sandy Hook, six F-86 pilots over March AFB, Capt. William Fairbrother near Mankato and Capt. Donald Slayton near Hastings all went up after objects and returned without answers. In Mankato the wingman saw nothing, and in Hastings the object was officially a balloon even though the pilot’s own report describes it turning and accelerating.
The Radar Crews: Okinawa, Selfridge, Westover, Goose Bay and a Cape Cod station tracked fast echoes, and operators at Fort Monmouth followed hovering targets. Yet at Andrews and Mankato the radar saw nothing at all, which left those cases resting on eyewitnesses alone.
The Scientists and Professors: Three Texas Tech professors counted flights of lights over Lubbock, and a student photographed them. The Air Force concluded birds, the photographs were never confirmed or ruled out, and the Pentagon’s project officer visited Lubbock in November 1951. Meanwhile an Ohio farmer’s call to Perkins Observatory on December 7 found no astronomer in.
The Air Force Investigators: The service carried each report on a record card and sorted it into balloons, meteors, aircraft and planets, leaving a small group Unidentified. In 1951 that group included Oak Ridge, Sunbury, Andrews and Mankato, and many of the Unknowns have an Air Force analyst saying, in effect, that the witness saw something but not what he claimed.
The Civilians: A farmer on a cemetery road in Italy, two lookouts in a jeep north of Mojave, a K-25 guard in a tower and a Kansas City policeman opening his garage all reported what they saw to authorities who had little to offer them. Some, like Slayton and Cathie Connelly, did not tell their stories fully until decades later.
The year’s pattern is one of contact without capture. Pilots closed on objects and lost them in a turn, radar crews tracked targets nobody could name, and investigators explained most of what reached their desks and could not explain the rest. The entity cases that fill the Unknown Date page share the same shape from the other side: single witnesses with stories no one could check. Together they make 1951 a year when the sky was full of reports and the answers never arrived.
“Suggest the observer saw something as stated in the report, but was in error as to the amount and speed of travel.”
