We were in the middle of a localized mini-flap of sightings which covered an area of Kansas around 500 square miles in extent. Many towns in southwestern and central Kansas had seen objects.
At 2:07am, the dispatcher in Colby received a phone call saying that there was an object in the sky to the northeast of town. Five minutes later Patrolman Paul Carter saw it. "It was big, very bright, changing from red and green blinking colors to bright white, so bright you couldn't look at it. It lit up the pasture". The object, a domed disk, hovered 10 to 15 feet above the ground. Carter said the thing was 30 to 35 feet in diameter and 20 to 25 feet high, sort of like a fat, inverted cereal bowl. Just above the bottom rim were located the large blinking red lights, circular in shape and in a horizontal line. Above them, scattered all across the top of the dome were the blinking green lights. There seemed to be no pattern to their flashing that Carter could determine.
Shortly his patrolling partner, Dennis Brown, arrived in another car. He witnessed the thing rise up from the field and cruise away to the southeast. Policemen from a nearby town reported that they had watched the object through binoculars for about four minutes as it gradually distanced itself from the area. What happened next is a little garbled but it seems that Carter and Brown tried to pursue the object, but every time they seemed to close a bit the object moved on. Finally, getting out of their normal jurisdiction, they gave up and turned back to Colby.
Their dispatcher told them to go and check on what had happened with the original fellow who had called at 2:07am. They arrived at John Calkins' residence and heard that he had been awakened by dogs barking their heads off at 2am. A saucer-shaped object was descending over a quonset building nearby and it was blazing bright. The object was a disk, 25 to 35 feet in diameter and 15 to 20 feet high. It had a dome and was making high-pitched noise [his dog was later found cowering with paws over ears]. The noise turned to something like Morse code beeping, which Calkins could not interpret. The thing was too bright to stare at, and it frightened the witness.
The reports do not say how this object left, but it was long gone by the time the officers showed up to talk to Calkins. [The presumption in all this is that both observations were of the same disk, and that as Calkins called the police, the disk left and was shortly seen by Carter]. Other than describing his own experience, Calkins' best quote was his remark about Carter and Brown. "They were white as sheets. I've never seen a police officer that scared in my life".
