Amazing 1950 UFO Photo Determined To Be The Real Thing

AMAZING 1950 UFO PHOTO DETERMINED TO BE THE REAL THING MAY 11, 1950    …..    McMINNVILLE OREGON A classic set of impressive UFO photos was taken by Mr. and Mrs. Trent in the early part of the evening, just before sunset, on May 11, 1950, near McMinnville, Oregon. According to the Trent’s account the object, as it appeared over their farm was first seen by Ms. Trent while she was feeding the farm’s rabbits  She then quickly called her husband who got the family’s camera and Mr. Trent then took two shots from positions only just a few feet apart. The pictures first appeared in a local newspaper and afterwards in Life magazine. Seventeen years later the photos were subjected to a detailed analysis for the University of Colorado UFO Project.  William K. Hartmann, an astronomer from the University of Arizona, performed a meticulous photometric and photogrammetric investigation of the original negatives, and set up a scaling system to determine the approximate distance of the UFO.  Hartmann used objects in the near foreground, such as a house, tree, metal water tank, and telephone pole, whose images could be compared with that of the UFO. There were also hills, trees, and buildings in the far distance whose contrast and details had been obscured by atmospheric haze.  Hartmann used these known distances of various objects in the photo to calculate an approximate atmospheric attenuation factor. He then measured the relative brightnesses of various objects in the photos, and demonstrated that their distances could generally be calculated with an accuracy of about +/- 30%. In the most extreme case, he would be in error by a factor of four. He then wrote:  “It is concluded that by careful consideration of the parameters involved in the case of recognizable objects in the photographs, distances can be measured within a factor-four error … If such good measure could be made for the UFO, we could distinguish between a distant extraordinary object and a hypothetical small, close model.”  Hartmann then noted that his photometric measurements indicated that the UFO was intrinsically brighter than the metallic tank and the white painted surface of the house, consistent with the Trent’s description that it was a shiny object. Further, the shadowed surface of the UFO was much brighter than the shadowed region of the water tank, which was best explained by a distant object being  illuminated by scattered light from the environment.   “it appears significant that the simplest most direct interpretation of the photographs confirms precisely what the witnesses said they saw”
