Richard Hammar was joined by physicist Dr. Greg Ojakangas and Cessna Citation pilot Erin Buskirk for a discussion of UFOs at a meeting of the Springfield (Missouri) Astronomy Club on June 22, 2010. Erin began the presentation by describing a UFO that he saw while flying at 45,000′ over Kansas on the evening of April 28, 2010. A recording made by Denver Air Traffic Control, obtained as a result of an FOIA request, was played. Several possible explanations of this, and other, UFO sightings were explored.
