5.4 Summary and Conclusion

On November 7, 2006 multiple witnesses reported sighting a
cryptic object or phenomenon over Chicago O’Hare International
Airport. The object or phenomenon presented itself as an
apparently solid yet featureless oblate spheroid which hovered
at a fixed altitude and attitude for a period of minutes before
suddenly ascending nearly vertically into and through the solid
cloud layer. The passage of the object through the clouds
apparently caused the creation of a sharp edged circular hole
somewhat larger in diameter than the object itself. We review
the literature and find that the Chicago incident appears to be
the latest example in a series of rare, but not unprecedented
incidents stretching back to at least 1947. Because of the
similarity of the phenomena in the reports, we seek a common
physical explanation for the HIC.

We consider the possibility that the HIC was produced by a
naturally occurring precipitation process, but reject that
hypothesis because neither freezing conditions, raindrops, nor
falling ice crystals were present at the time and location in
question. We postulate that sudden in situ evaporation of the
water droplets constituting the cloud represents the least
extraordinary physical process capable of explaining the
observations. We estimate the minimum volumetric energy density
required to cause such in situ evaporation as approximately 9.4
kJ/m3, in the form of heat. We consider the remote possibility
that a blunt body moving at high subsonic velocities through the
air may dissipate sufficient amounts of aerodynamic energy
through viscous friction to cause this amount of heating, but
find that the likely heat production rate is too low. We
postulate that the instantaneous nature of the HIC formation,
the circular shape, and its sharp edges all point to the direct
emission of, for example, electromagnetic radiation from the
surface of the oblate spheroid as the proximate cause of the
HIC. We cannot identify the object or phenomenon lying inside
the oblate spheroid surface, but two conclusions seem
inescapable: 1) the object or phenomenon observed would have to
have been something objectively and externally real to create
the HIC effect; and, 2) the HIC phenomenon associated with this
object cannot be explained by either conventional weather
phenomena or conventional aerospace craft, whether acknowledged
or unacknowledged.
