http://sheilaaliens.net/?p=1053 Found out about this via facebook. Multiple videos from users on Facebook and Youtube. Stabilized a bit by Sheilaaliens.
UPDATE: According to KYMA News, the military has taken responsibility for this sighting. :/ (think what you want, still a pretty cool thing to see, IMO.)
