My dad was outside with his wife and they saw a light wheN they turned to look they saw a large craft hovering. It made no noise. It had stationary blue lights on top and pulsating white lights around the bottom. Suddenly, still without making a sound it zipped to the right, zipped back to the left and that flew away at a crazy speed. My father said he felt it was a craft from the start. While I have believed in UFOS since childhood I have alays known my dad to be a skeptic, now he stands outside every night looking for another one.
