A 1958 UFO sighting that corroborates the Trindade UFO photos....but wait, Trindade has been deemed a hoax.
June 14, 1958; Pueblo, Colo. (BBU 5852)
10:46 a.m. Airport weather observer O. R. Foster, using a theodolite, sighted an object shaped like Saturn, less the bottom part, silver with no metallic luster, which flew overhead. (Berliner)
From (which also has some other sightings you might find interesting):
TIME/PLACE OF SIGHTING: June 14, 1958, at 10:46 A.M. MST/Memorial Airport at Pueblo, Colorado.
DURATION: Five minutes.
NUMBER OF OBSERVERS: One.
TYPE OF OBSERVER: Meteorologist for U. S. Weather Bureau.
NUMBER OF OBJECTS: One.
OBSERVER RELIABILITY: Excellent.
SHAPE: Like the planet Saturn with its rings tilted forward and without bottom of planet showing.
DIMENSIONS: At least 30 feet in diameter.
ALTITUDE: When UFO first appeared it was 24.2º above horizon; when it disappeared it was 8.1º above horizon: minimum altitude was at least 30,000 feet.
SPEED: Minimum of 500 miles an hour.
TACTICS: Moved across a large area of sky from almost due west to southwest.
COMMENT: Observer was an experienced meteorologist (28 years with U.S. Weather Bureau) and was observing a pilot weather balloon through his theodolite when the UFO crossed his field of view. He followed it with the optical instrument, timing its passage across the sky. It was sharply defined and definitely was not a balloon.
It's odd that a Saturn-like UFO would appear in reality and via an alleged hoax in 1958, the hoax in January and the "actual UFO" in June.
So. were the Trindade Island photos phony or not? The matter remains moot.
