b. Pendulum/Falling Leaf Motion
A curious, but fairly common, flight characteristic of UFOs is a pendulum-like motion (swaying back and forth) during hovering, slow climb, or descent. Witnesses frequently have compared this to the gyrations of a falling leaf.
Sample Cases:
October 11, 1951. J.J. Kaliszewski (then Supervisor of balloon manufacture for General Mills, Inc.) and Dick Reilly were flying near Minneapolis, Minnesota, observing a balloon at 6:30 p.m. They noticed a bright glowing object overhead moving at high speed from east to west. The UFO had a dark undersurface, and a halo of light. Finally it slowed, and started climbing "in lazy circles." Kaliszewski: "The pattern it made was like a falling oak leaf inverted." [Section VI.]
February 9, 1957. At 1:00 a.m. in Philadelphia, Pennsylvania, Roger Standeven observed a white oval-shaped UFO with a red light visible on top. The object would stop, "fall like a leaf," speed up again, and repeat the sequence, gaining altitude each time it sped up.
[For other examples; See Section XI, Chronology: 9-20-52, 9-26-54, 11-25-56, 2-28-61.]
(c) Side-to-Side Oscillation
A very similar pendulum-like motion, occurring as a UFO travels in a horizontal plane (rather than ascending or descending) has been noticed occasionally. It consists of a side-to-side oscillation as the UFO proceeds in a constant direction.

(3) Violent & Erratic Maneuvers
In a sample of 40 cases in which erratic maneuvers were reported, there is a noticeable repetition of certain motions which appear to be characteristic of many UFOs. All of the cases involve UFOs which abruptly altered direction and/or speed, usually more than once during the observation. Of the total, 63 percent occurred during night hours.
Reported Shapes:
43 percent round or elliptical UFOs, 50 percent light sources only (no shape discernible).
Witnesses:
28 percent scientific or experienced; 33 percent good; 39 per cent average.

Hovering & bobbing UFOs
In 14 cases (35%) the UFOs jumped or "bobbed" around while hovering in one general area of the sky, moving abruptly up and down, side to side. The words "bobbing," "erratic" and "jerky" regularly appear in the report. Sometimes the maneuvers are compared to the bouncing of a ping-pong ball. At least one witness said the motion was like the bobbing of a float on a fishing line.
