1.0 Executive Summary

This report presents the results of an investigation into an
interesting incident at O'Hare International Airport (ORD) on
November 7, 2006 at about 1615 hrs (4:15 pm) CST that had
definite safety implications. A number of highly reliable
airline employees and others reported seeing a round, revolving,
gray, metallic appearing object [hereafter called an
Unidentified Aerial Phenomenon (UAP)] hovering approximately
above United Airline's Gate C17 in Concourse C at an altitude
less than 1,900 feet above ground level (AGL) and departing
sometime between 4:18 and 4:33 pm. Since two United taxi
mechanics reported seeing the object sometime after 4:00 pm the
object could have been present for at least eighteen minutes or

The following subjects are discussed here: Description of eye
witness accounts, overview of O'Hare International Airport and
its aviation operations, visibility from the control tower,
weather conditions, the reported hole in the cloud allegedly
caused by the UAP, radar technical considerations and possible
primary contacts, safety implications of the incident, and a

Appendices also present a discussion of hoax data, press
coverage of the event, reports of UAP made by other alleged
witnesses in the area on that day, a description of typical
cockpit duties during an approach, landing, and taxi to gate and
other relevant documents.

Based on eye witness testimony the UAP would have ranged in size
from about twenty-two to eighty eight feet diameter. It
accelerated at a steeply inclined angle through the 1,900 ft
cloud base leaving a round hole approximately its own size that
lasted for as long as fourteen minutes. This is suggestive of a
super heated object or otherwise radiated (microwave?) heat
energy on the order of 9.4 kJ/m3. According to the FAA nothing
was detected by radar at this location or time of day or seen by
air traffic controllers from the main tower. An examination of
primary radar data supplied by the FAA confirmed the first
claim. Nevertheless, an FAA inbound ground controller remarked
about the "UFO" (UAP) at about 3:58:09 pm, long before the
object had departed. No reference to a UAP IS made by any
inbound or outbound flight crew other than two United
maintenance taxi mechanics moving an empty airplane to the
maintenance hanger on the north side of the airport. Of course
this does not mean that there was no object present but only
that these flight crew did not discuss it over the radio.

Our analyses suggest that a potentially significant air safety
problem existed at O'Hare International Airport on the afternoon
of November 7, 2006. 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, constitutes a
potential threat to flight safety. The identity of the UAP
remains unknown. An official government inquiry should be
carried out to evaluate whether or not current sensing
technologies are adequate to insure against a future incident
such as this.
