The Encounter

Kase Best is a former army officer who had a UAP encounter on February 15, 2022, while walking to a briefing at a military base in Colorado. He and four colleagues observed a large, elliptical object hovering over Cheyenne Mountain. The object was white, made of irregular pentagonal panels, and appeared to be about 300 feet long and 150 feet high. It was completely still and silent, and after about 30 seconds, it vanished without any movement. After the sighting, Kase did not report it immediately due to the urgency of his duties. He later documented the event and submitted a report to the Pentagon's UAP office, but he felt their response was unprofessional and dismissive. He eventually reported the incident to the FBI, who took his account seriously.
