Those familiar with the story will doubtless have seen many television productions describing the tale, along with depictions in books and magazine articles."}},{"type":"paragraph","data":{"text":"The basic details of the story have been frequently recounted in UFO-related literature. An unusual object was seen in the skies above Godman Field at Fort Knox, Kentucky, on January 7, 1948, spanning a period from 2:40 pm central time until 4:00 pm and beyond. Other reports claim that a similar object was seen hours earlier, and possibly even after the intercept. What is known is that multiple personnel at Godman Field at Fort Knox, Kentucky saw something large and unusual in the sky above their location. At that time, the C Flight of the 165th Fighter Squadron, Air National Guard, composed of four P-51 Mustangs under the command of Captain Thomas F. Mantell was flying from Marietta, Georgia to Standiford Field, Kentucky in Louisville. They were on a routine training mission when the tower personnel at Godman Field asked them to divert and investigate the unidentified object that had been seen over the airfield. "}},{"type":"paragraph","data":{"text":"At that point, Mantell and two of the other pilots in his squadron diverted to Godman Field to search for the UFO that had been reported. The fourth pilot continued on to Standiford Field. At this point, the ensuing events become the subject of contentious debate, but there is a comprehensive body of evidence found in government documents that allow us to provide a closer examination of these events. What is known beyond any question is that Thomas Mantell did not survive his encounter with whatever anomalous object he was dispatched to investigate."}},{"type":"image","data":{"file":{"url":"https://tdbrf.com/wp-content/uploads/2022/02/p51.jpg"},"caption":"A P-51D Mustang, similar to the one flown by Mantell in 1948 (Photo credit: National Museum of the Air Force)."}},{"type":"paragraph","data":{"text":" "}},{"type":"header","data":{"text":"SEPARATING THE MYTH FROM THE HISTORICAL RECORD","level":2}},{"type":"paragraph","data":{"text":"There are many reports of this event containing the same descriptions and sensationalized reports of Mantell dying in pursuit of a UFO.

The same is true of many other supposed documentaries reporting on this event. Locations, depictions of the UFO in question, reports from witnesses and pilots... they are all riddled with errors. Also, the source material itself, involving testimony from multiple primary witnesses, is contradictory in places and requires serious examination to separate the wheat from the chaff.

For example, references are made of a sighting at the same time in Kentucky over \"Mansville,\" and \"Maysville\" as well as \"Madisonville,\" despite the fact that two of the locations are more than 100 miles apart.

Mantell himself, with the unfortunate exception of one critical moment. There is little to no disagreement from the witnesses about his role in the day's events with some minor exceptions regarding his wording when speaking to the control tower. There was also one witness who thought Mantell's squadron consisted of five planes instead of four and another who only recalled seeing three. That latter number is easily explainable, however, as we shall cover here."}},{"type":"paragraph","data":{"text":"Mantell was leading his squadron of four P-51 Mustangs on a routine training flight en route from Marietta, Georgia heading to Standiford Field, Kentucky in Louisville. Standiford is only a short distance to the northeast of Fort Knox and Mantell's flight path would take him almost directly over Godman Field."}},{"type":"paragraph","data":{"text":"By the time the squadron was approaching Godman at approximately 4:00 pm, the sighting of the object had been going on for ninety minutes. The tower at Godman radioed and asked Mantell's squadron to divert and investigate the sighting.

He reported that when he arrived, Mantell's body \"had been removed from the aircraft.\" (It was likely ejected at some point.) Eyewitnesses told the officer that they had seen the plane coming down nose-first in a steep dive and that the plane had either \"exploded\" or \"disintegrated\" in the air before striking the ground. The craft did not burn up after impact. The wreckage was reportedly spread out for over a mile and the tail section, the propeller, and one wing were not initially located."}},{"type":"paragraph","data":{"text":"Reports of when the tower last had radio contact with Mantell vary, but it seems to have been between 4:15 and 4:30 pm. The crash of Mantell's plane in Franklin, Kentucky took place at approximately 4:45 pm according to civilian witnesses.

The slow speed and size of the object have led some to suggest it may have been a blimp or perhaps a skyhook balloon. These balloons were developed in the 1940s and the general shape could be a good fit for the \"teardrop\" shape described by witnesses.

Would they not have been able to identify a balloon?"}},{"type":"paragraph","data":{"text":"As for what happened to Mantell, investigators concluded that he became hypoxic after flying higher than 20,000 feet. This does not explain how pilot Clements was able to climb to 33,000 feet in the same model P-51 when he returned to continue the search, however. That's also well below the maximum rated altitude of the P-51 Mustang. A later report from Orner confirmed that"}},{"type":"paragraph","data":{"text":"Clements did obtain a fresh supply of oxygen while refueling, so perhaps Mantell ran out without realizing it.

This has led to the suggestion that it had taken some sort of offensive action against him. But as noted above, Mantell's plane flew more than 90 miles before crashing, presumably without a conscious pilot controlling it."}},{"type":"paragraph","data":{"text":"Would that have happened to a plane with an unconscious or deceased pilot at the controls? A look at the flight controls of the P-51 doesn't make that entirely clear. But a view of the center stick control column in the cockpit and how the pilot's body is oriented, along with the position of the pilot's hand on the controls offers some clues. If the pilot were to become unconscious or die, their hand would almost certainly drop off of the stick. The pilot's harness would prevent the body from leaning forward onto the stick. With no hand on it, the Mustang's center stick would spring back to the default position of orienting the plane for steady forward movement at a constant altitude."}},{"type":"paragraph","data":{"text":"Provided the plane was oriented toward the south when Mantell was disabled and there was sufficient fuel left in the tank, it's not difficult to see how the aircraft could have flown to Franklin, Kentucky before the engine died.

Well, the P-51 is a very \"nose-heavy\" aircraft."}},{"type":"paragraph","data":{"text":"There is still no \"smoking gun\" in terms of what actually happened to Thomas Mantell in the final moments when he approached the unidentified object. Nor are we left with a definitive conclusion as to what the object was.
