The UFOCAT documents 180 instances of pendulum or “falling leaf” maneuver by UFOs. In two of those instances (Reports Number 16,982 and 87,715) the maneuver is executed in reverse. The UFO falls like a leaf UPWARDS before accelerating away. UFOs are perfectly capable of going straight up or down. Belgian radar recorded a drop by a UFO of 3,000 feet in 2 seconds. So why the occasional pendulum or falling leaf motion?
There do not appear to be any sketches by witnesses of this motion, upwards or downwards, but it probably looked something like this:
Providence Journal, Providence, USA, page 3, on July 6, 1947
Eight flying saucers were reported today to have made a landing on a mountainside near St. Maries, Idaho in full view of 10 persons.
Mrs. Walter Johnson of suburban Dishman said the saucers came down in timber there Thursday evening but had not been reported until she returned to her home in Dishman today.
The saucers were seen to fall near Butler's Bay on the St. Joe River six miles west of St. Maries, where Mrs. Johnson was visiting her parents.
She said they came into view at an extreme speed, traveling from the south to the north. Suddenly, they slowed, she said, and then "fluttered like leaves to the ground."
"The mysterious part was that we couldn't see them after the landing," said Mrs. Johnson. "We could see them flutter down into the timber, yet we couldn't see that they did anything to the trees."
Both the CAA and the Army Air Corps officials were notified of the incident but no immediate plans for an air search of the area were announced.
There is a report for that date from Otis AFB, approximately 80 nautical miles southeast of Nashua. The time of the sighting isn't clear, as it was reported as being sighted between 6:30 and 7:30 p.m. Eastern Standard Time, but was also reported as lasting 15-20 minutes. The Project Blue Book file consists primarily of a telex from Otis AFB to several recipients, including Air Defense Command, Project Blue Book, and the Directorate of Intelligence in Washington D.C., the relevant portion of which reads...

Father Gill's log of events and a summary report by his colleague, the Reverend Norman Cruttwell:
"Another peculiar thing was this shaft of blue light. which emanated from what appeared to be the center of the deck. The men appeared to be illuminated not only by this light reflected on them, but also by a sort of glow which completely surrounded them as well as the craft. The glow did not touch them, but there appeared to be a little space between their outline and the light.. . . ''
Father Gill described the movements of the objects, especially the smaller disks, as very erratic. They sometimes moved rapidly, sometimes slowly, approaching and receding, changing direction, and at times swinging back and forth like a pendulum. One object moved away and appeared to descend toward Wadobuna village, and everyone thought it was going to land. The Papuana ran down on the beach, but the object swooped up and away over the mountains, turning red as it disappeared.
It could also be a type or defensive maneuver, making it's trajectory unpredictable. I think this idea makes more sense as they should be able to control the craft without such a seemingly random movement.
My stray thought about the falling leaf or pendulum motion UFOs is that they are only appearing to move that way to us, whereas in the multidimensional reality in which they exist, it might be a straight line. The shortest distance between two points not in the same dimensional structure.
A version of that old "Flatland" notion Carl Sagan used to talk about. Because of our limitations in perceiving only 3-4 dimensions, we don't get the whole, true picture.
The craft was then approximately motionless above the Saint-Félix point; but it soon started to go down with a slow rocking movement, like a falling leaf, and disappeared soon behind the point, which is a high hill. The appearance had lasted several minutes.
1954 – Dr. Robert, driving through Baillolet, France at nightfall, saw four objects flying slowly in echelon formation at about 300 meters altitude. One of UFOs dropped abruptly to the ground with a falling leaf motion, landing only 100 meters away. The witness felt an electric shock as the engine and headlights of his car died, and his car stopped the moment the object touched the ground. Incapable of moving, Dr. Robert watched as a figure about 1.2 meters (4 feet) tall moved around in the light of the object, then all went dark. Some time later the headlights came back on by themselves, and Dr. Robert saw the craft take off toward the north.
