On march 7, 2020, at approximately 0056 hours, i was on routine patrol traveling east on us hwy166 east of bartlett in labette county, kansas. at approximately u166 hwy and udall road, i observed a very bright solid star-like circular light hovering over a field on the south side of the hwy. initially i thought the light was possibly a very bright star or possibly a visible planet. as i continued west on the hwy i noticed i was getting closer to the light. the light appeared as if it was only approximately 250â€™ to 300â€™ above the field. my first thought was that the light may have been a cell phone tower, even though i was almost certain there were no cell phone towers at the particular location. on the hwy, approximately east of scott road, i found myself parallel from the light/object. i observed a large circular white light on the ground directly below the object. the circular light on the ground appeared to be approximately 100â€™ in diameter. the circular light on ground looked as if it was casted from the light/object above. as i was driving past the light/object, i looked through my driverâ€™s side window to see if the light was suspended in the air by a structure or tower and observed nothing. my next thought was the light must be from a helicopter. i rolled the drivers side window down on my patrol unit listening for the sound of a helicopter, but there was no sound to be heard. confused, i decided to turn around. i proceeded east on u166 back toward the object. the object remained in the same spot it had been, only for seconds longer, then took off eastbound at a high rate of speed. the object continued east and disappeared a few seconds later on the horizon. i logged the incident with my dispatch on our secure channel and returned to my normal patrol duties. later i was able to go back on my patrol units in car video and choose a record after the fact option. from the video i screen shouted a zoomed in photo of the light, (attached below).
