U.S. Air Force Analysis of Flying Objects in the United States, 1-100

Mr. Kauke who was driving the car noticed the object first. He called it to the attention of the other occupants. Mr. Zohn thereupon opened the window nearest him and observed the object moving at an unknown radial velocity at an unknown altitude (which he estimated at 10,000 ft) and which Mr. Kauke thought was between 8,000 and 10,000 feet. When first sighted the object was to their right and forward of the automobile at an unstated elevation and apparently moving horizontally in a Northerly direction such as to cross the highway from right to left. The object was seen by all the documents of the machine. Mr. Zohn could observe no details other than the shape was uniform with no protuberances such as the wings of a plane. It was too distant to enable stereoscopic visualization. There was some solar specular reflection which seemed to change in intensity as the object receded until lost from sight (after an estimated 30 seconds from the time first noticed.) Mr. Zohn could not explain how it disappeared except that he thought the reflection angle could have changed abruptly. The sun was to the rear of the automobile. Mr. Kauke thought at one time he saw vapor trails.
