The Chiles-Whitted UFO encounter occurred on July 24, 1948 in the skies near Montgomery, Alabama. Two commercial pilots, Clarence S. Chiles and John B. Whitted, claimed that at approximately 2:45 AM on July 24 they observed a "glowing object" pass by their plane before it appeared to pull up into a cloud and travel out of sight. According to Air Force officer and Project Blue Book supervisor Edward J. Ruppelt, the Chiles-Whitted sighting was one of three "classic" UFO incidents in 1948 that convinced the personnel of Project Sign, Blue Book's predecessor, "that UFOs were real." However, later studies by Air Force and civilian researchers indicated that Chiles and Whitted had seen a meteor, possibly a bolide, and in 1959 Project Blue Book formally stated that a meteor was the cause of the incident.
In the early morning hours of July 24, 1948, Clarence Chiles, chief pilot, and John Whitted, co-pilot, were flying an Eastern Airlines Douglas DC-3 passenger plane near Montgomery, at about 5,000 feet altitude. The night sky was clear with "the Moon, four days past full, shining through scattered clouds."
At about 2:45 AM, Chiles "saw a dull red glow above and ahead of the aircraft." He told Whitted "Look, here comes a new Army jet job." The object closed on their DC-3 in a matter of seconds, and both men later said they saw the object fly past the right side of their plane at a high rate of speed before it pulled "up with a tremendous burst of flame out of its rear and zoomed up into the clouds." They observed the object for a total of 10 to 15 seconds. Chiles and Whitted stated that the object "looked like a wingless aircraft...it seemed to have two rows of windows through which glowed a very bright light, as brilliant as a magnesium flare." Both pilots claimed the object was 100 feet long and 25-30 feet in diameter, torpedo-or-cigar shaped, "similar to a B-29 fuselage", with flames coming out of its tail. Only one of the plane's passengers, C.L. McKelvie, saw anything unusual. He reported seeing a "bright streak of light" that flashed by his window.
Shortly after landing in Atlanta, Georgia, Chiles and Whitted reported their sighting to the US Air Force. They were interviewed by personnel from Project Sign, the first Air Force research group assigned to investigate UFO sightings. The personnel found that the two pilots did disagree on some details: Chiles claimed to see a lighted cockpit, long boom on the nose of the object, and the center section was transparent. Whitted did not see a cockpit or boom, and instead of the center section being transparent he claimed to see a series of rectangular windows. Neither pilot had heard any sound, and although some books and articles would later claim the plane had been hit by turbulence from the object, both pilots and the passenger who saw the "streak of light" stated that the plane was not affected at all by the object.
