On November 7, 2006, an unusual event unfolded at O'Hare International Airport in Chicago, capturing the attention of ufologists and aviation experts alike. This incident, known as the O'Hare UFO incident, involved multiple witnesses and sparked numerous investigations.
O'Hare International Airport
The Sighting
It all began when 12 United Airlines employees and several other witnesses outside O'Hare International Airport reported a sudden UFO sighting. A ramp employee, who was pushing back United Airlines Flight 446 (departing for Charlotte, North Carolina), first spotted the object above the aircraft and informed the flight crew.
Witnesses described the object as:
- Completely silent
- Dark gray in color
- 6 to 24 feet (1.8 to 7.3 m) in diameter
One witness described a disc-shaped craft hovering over the airport, stating it was "obviously not clouds." According to this witness, the object shot through the clouds at high velocity, leaving a clear blue hole in the cloud layer, which reportedly closed itself shortly afterward.

Initial Reactions and Investigations
Initially, both United Airlines and the Federal Aviation Administration (FAA) denied having any information on the O'Hare UFO sighting. However, the Chicago Tribune, investigating the report, filed a Freedom of Information Act (FOIA) request, leading to further scrutiny.
The FAA speculated that the phenomenon might have been a "hole punch cloud," also known as a fallstreak hole. This occurs when an aircraft passes through supercooled water droplets in the cloud, causing them to turn into ice crystals and precipitate out, leaving a hole.
However, a formal scientific report on the O'Hare International Airport UFO incident was quietly released on July 27 by the National Aviation Reporting Center on Anomalous Phenomena (NARCAP). This 155-page report was produced by analysts with backgrounds in physics, meteorology, and engineering, including some with NASA experience.
The NARCAP Report
The NARCAP report meticulously reconstructed the incident using FOIA records, ground crew accounts, and maps. It challenged the FAA's "weather phenomenon" explanation. The report estimated the object, measuring 22 to 88 feet in diameter, hovered over O'Hare for up to 18 minutes before creating a circular tunnel through a 1,900-foot cloud ceiling at a steep angle.
NARCAP called for a government inquiry and improved energy-sensing technologies, stating that "Anytime an airborne object can hover for several minutes over a busy airport but not be registered on radar or seen visually from the control tower, (it) constitutes a potential threat to flight safety."

Other UFO Sightings in Illinois
Hundreds of UFO sightings are reported in Illinois every year. Here are some of the more plausible cases from the database, along with insights from Sam Maranto, state director of the Illinois Mutual UFO Network.
Case Study #1: The Rockford Orbs
- When: 1999-2001
- Where: Rockford
- What happened? A formation of orange orbs appeared repeatedly over the Rock River valley, floating leisurely across the sky before disappearing.
- Maranto's Take: "Of the 13 nights of sightings up there, I could substantiate the bulk of it as legitimate."
Case Study #2: The Champaign Beams
- When: February 2, 2002
- Where: Urbana-Champaign
- What happened? Clusters of amber-hued lights flashed in a line across the sky, observed by students and residents. A police officer reported objects hovering above Memorial Stadium and chatter about unidentified objects on his scanner.
- Maranto's Take: Victor Connor, an Illinois Mutual UFO Network field investigator, calls the case legit. "Nobody knows what it was. It wasn’t planes; it wasn’t balloons. But it was pretty minor."
- Creepy detail: One witness said some buildings were lit up with spotlights originating from the objects.
Case Study #3: The Tinley Park Lights
- When: August 21, 2004
- Where: Tinley Park
- What happened? Three red lights hovered in a triangular formation for almost half an hour and then flickered out, one by one.
- Maranto's Take: "This is the case. A hell of a lot of people saw it." Several videotapes exist, including one that Maranto says shows objects flying in and out of the lights.
Case Study #4: Return of the Tinley Park Lights
- When: October 31, 2004
- What happened? The "Tinley Park Lights" returned, viewed by hundreds of witnesses.
- Maranto's Take: "The lights were visible by observers from at least 12 miles away-so that pretty much rules out a hoax. And this object was frigging massive. It was as big as the Tweeter Center."
- Creepy detail: Maranto claims that, in a video, what look like helicopters appear to be keeping planes away from the area.
Case Study #5: The St. Clair Triangle
- When: January 5, 2000
- Where: St. Clair County (across the Mississippi River from St. Louis)
- What happened? One witness snapped a photo, but it was inconclusive.
- Maranto's Take: "This is a topnotch sighting. Because the area was mainly rural, light pollution wasn’t [as] prevalent as in Tinley Park. They all saw the object[s] maneuver like nothing prosaic."
- Creepy detail: "As it passed," one witness claimed.
Mike Moss's Weather Perspective
Meteorologist Mike Moss examined news reports about the incident but found no specific explanations regarding weather phenomena. While weather conditions can contribute to UFO reports (e.g., mirages, lenticular clouds), the data from O'Hare and surrounding areas on the date in question didn't lead to any obvious conclusions. The low overcast reported at 1900 feet AGL would have been well above freezing and not subject to the "hole punch" cloud phenomenon. Strong mirage phenomena were also unlikely.
In conclusion, the O'Hare UFO incident remains a fascinating and debated event. The detailed accounts from numerous witnesses, combined with the NARCAP report, raise important questions about aviation safety and the need for improved detection technologies.
