Capt. Edward Ruppelt:
I almost overlooked the report from the radar station because it was fairly short. It said that early on the morning of August 26, only a few hours after the Lubbock sighting, two different radars had shown a target traveling 900 miles per hour at 13,000 feet on a northwesterly heading. The target had been observed for six minutes and an F-86 jet interceptor had been scrambled but by the time the F-86 had climbed into the air the target was gone. The last paragraph in the report was rather curt and to the point. It was apparently in anticipation of the comments the report would draw. It said that the target was not caused by weather. The officer in charge of the radar station and several members of his crew had been operating radar for seven years and they could recognize a weather target. This target was real.

I quickly took out a map of the United States and drew in a course line between Lubbock and the radar station. A UFO flying between these two points would be on a northwesterly heading and the times it was seen at the two places gave it a speed of roughly 900 miles per hour.

This was by far the best combination of UFO reports I'd ever read and I'd read every one in the Air Force's files.
