Comparing the UFO shape to type of “porthole”, to determine whether a particular type of UFO tended to have a particular type of “porthole”, the findings were largely negative. The UFOs reported as cigar-shaped (11 cases) did not have rectangular “portholes” — with one exception (November 22, 1961).
Circular or disc-shaped objects (19 cases) were reported as having circular “ports” in 4 cases, rectangular in 6 cases, rows of lights in 7 cases.
Elliptical or oval UFOs (10 cases) were reported as having rectangular “ports” in 5 cases, circular in 3 cases, rows of lights in 1 case.
The most striking consistency or pattern to “porthole” reports is the description of their arrangement on the body of the UFO. In no case were the lights or markings arranged haphazardly. On the contrary, in every case the “portholes” were arranged either in straight lines, or circular patterns (most often around the curved surface).
In many cases the “portholes” were arranged exactly along the major axis of UFOs which presented elliptical outlines to the observer.
The “row of lights” cases, alone, consist of two basic types: (1) Lights on or adjacent to the edge of a disc. (In two cases, witnesses reported the lights were just below the disc edge, on the underside of the UFO.) (2) Lights along the length of cigar-shaped UFOs.
The position and geometrical arrangement of the “portholes,” and the light usually associated with these markings, strongly suggest that they are indeed ports or vents. They could well be actual windows, particularly those of distinctly square or round construction. The “row of lights” cases are subject to several different interpretations: (1) Lighted windows seen at greater distance; (2) Running lights, such as those on normal aircraft; Exhaust or propulsion vents.
B. MANEUVERS
A study of hundreds of UFO reports has revealed several recurring maneuver patterns. These include:
* Hovering (or very slow motion) and sudden rapid acceleration.
* Circling and pacing of human vehicles. [Section II.]
* UFOs rendezvousing, then operating together [e.g., Aeronautical Engineer report, July 16, 1952, Section VI; Airline Pilot report, July 14, 1952, Section V]
* Satellite objects, associated with and maneuvering around larger central parent objects. [Section II.]
Numerous examples of these features appear in previous sections, especially Section II which discusses the evidence that UFOs are intelligently guided. A number of rendezvous cases is included in the formation chart, Section II, and other examples may be found throughout the report.
The remaining feature, hovering followed by rapid acceleration, occurs so regularly that it can practically be considered a defining characteristic of a “UFO.” No man-made objects or known natural objects can perform in the manner described. The objects which were observed performing this maneuver were predominantly the typical discs and ellipses so often reported.
The following table lists one hundred sample cases between 1947 and 1962, illustrating this feature.
