The double hat UFO is so called because of it’s resemblance to two hats placed rim to rim, or perhaps two pie dishes placed lip to lip.
Dimensions for this craft vary in size from 1 to 30 meters. In daylight these are a brightly polished silver colour to a dull aluminum appearance. Flat- bottomed saucers are often darker underneath.
At night they are solidly lighted in red, orange, amber, yellow, blue or blue-violet, and brilliant white, singly or in combinations. The nighttime halo tends of obscure the vehicle, making the edges indistinct. Often on the double hat, or pie pan saucer, a rim of light may be wrapped around the middle.
When witnessed these objects seem at times to vibrate heavily. If the object is moving slowly, the movement seems jerky or jittery. It is difficult to know whether the jitter is an actual motion or an optical effect. At close quarters these craft may be accompanied by a buzz, hum or whine. The sound rises in both pitch and intensity seconds before and during takeoff from a hovering or landed position.
Report 1
UFO student Antonio Rebera gives an interesting account of the landing of a saucer on February 6th 1966 at Aluche, Spain, a suburb of Madrid with new apartment buildings interspersed with open spaces.
The saucer landed in an open space, perhaps larger than a city block. From the street bordering the clear area, witness Jose Louis Jordan watched a luminous, fiery disk approach, hover momentarily, and land about 8 PM. During it’s approach, it lowered a tripod landing which it sat down on.
The saucer was shaped like two big pie pans placed rim to rim and was estimated to be 10 to 12 meters in diameter. In a few minutes it rose, the landing gear disappearing as it did so. Sr. Jordan was overcome by the experience. Instinctively he tried to locate other witnesses, but he was too late.
The vehicle had gone, but it had left impressive evidence of its visit. Pressed into the hard Spanish soil were three neat footprints of the landing gear, arranged in an equilateral triangle of 6 meters, imprint to imprint. The prints were rectangular with rounded corners and each had a raised X-mark of half-round cross section on the bottom. They had clearly been made by a heavy or massive vehicle in a vertical landing, as the prints were clear-cut.
Report 2
SEEN IN BROAD DAYLIGHT
Large craft that looked like two pie plates facing each other with a short cylinder in between, yellow and orange… I was sitting in history class in the eighth grade (four years ago) when I happened to glance out the window and see a large object about 50 yards in diameter floating over my neighborhood in the northwestern suburbs of Austin.
It looked to be about half a mile away and moving slowly at a speed of 20 to 30 mph. It was only about 50 feet off the ground so I know that others must have seen it as well.
The top and bottom pie plate-shaped portions of the craft were orange and the center cylindrical portion was yellow. I don’t think it was metallic because I couldn’t see any kind of a shine (and the sun was very bright at the time with no cloud cover at all). I blinked a few times to make sure I wasn’t seeing things and then turned to one of my classmates to see if I could get another witness. When I turned back to look out the window 2 seconds later the object had completely vanished.
