Executive Summary
On November 7, 2006, around 4:15 p.m. local time, a group of United Airlines employees at Chicago’s O’Hare International Airport reported seeing a mysterious unidentified flying object (UFO) hovering over Gate C17 in the United terminal[1]. The object was described as a metallic, disc-shaped craft, dark gray in color, about 6 to 24 feet in diameter, and it was completely silent[2]. After several minutes of hovering below a low cloud ceiling, the disc abruptly shot upward at high velocity, punching a crisp circular hole through the clouds before disappearing―an occurrence witnesses described as “like somebody punched a hole in the sky”[3][4]. Despite multiple credible eyewitness accounts, including airport pilots, mechanics, and managers, the Federal Aviation Administration (FAA) initially denied any knowledge of the incident and declined to investigate, later suggesting that the sighting was caused by a weather phenomenon[5][6]. To this day, the O’Hare airport UFO encounter remains unexplained, and it is often cited as one of the most notable UFO sightings of the 21st century, raising questions about aviation safety and how such incidents are handled by authorities[7][8].
The Sighting: November 7, 2006
The incident unfolded on a cloudy afternoon at one of the world’s busiest airports. At approximately 4:15 p.m. CST on November 7, 2006, a ramp employee on the tarmac at O’Hare Airport spotted an unusual object hovering above Gate C17 in Terminal 1 (the United Airlines concourse)[9][10].

This worker was in the process of directing United Flight 446, a Boeing 737 bound for Charlotte, when he looked up and saw a disc-shaped “craft” directly above the gate area[9]. He notified the departing flight’s cockpit crew about the object, and word of the sighting quickly spread through United’s ground personnel via radio. Soon, dozens of other airport employees — including pilots in nearby aircraft, airline supervisors, mechanics, and ramp workers — rushed to get a look at the phenomenon[11][12].
Witnesses observed the object hovering at an altitude they estimated to be anywhere from roughly 500 to 1,500 feet above the ground, just under the cloud layer that day[13][14]. Everyone agreed it had a distinctly defined saucer-like shape and a dull metallic gray color. No lights were visible on it, and it made no sound whatsoever[13]. Some witnesses described it as rotating like a Frisbee, while others thought it appeared stationary despite its spinning-disc appearance[13][15]. All eyewitness accounts concurred that the object was definitely not an airplane or any familiar aircraft; it lacked wings, engine noise, or standard navigation lights[16][14].
After hovering in place for several minutes above Gate C17, the UFO abruptly accelerated straight up. It shot vertically through the overcast sky at a tremendous speed, causing a peculiar visual effect: as it pierced the cloud deck (estimated at ~1,900 feet altitude that day), it left behind a clean, circular hole in the cloud cover[3][4]. Multiple witnesses saw this hole appear in the otherwise unbroken cloud ceiling. They reported that the hole lingered for a few minutes as a window of clear air before the clouds gradually drifted in to close it[4]. One United employee later vividly remarked, “It was like somebody punched a hole in the sky”, referring to the sudden opening the object created[4]. This strange hole-punch effect, coupled with the object’s sudden departure, left witnesses both astonished and uneasy.
Eyewitnesses estimate the UFO hovered for roughly 5 to 10 minutes in total before it departed[18][19]. During that period, it remained motionless just below the cloud ceiling, offering observers on the ground a clear view of its shape and color against the overcast sky[13]. The object was small relative to a commercial airliner — various accounts guessed its diameter was anywhere from around 6 feet up to 24 feet across
