Bright red large light spotted moving very fast, Okinawa, Japan.On December 28th 2010 around 0030, I witnessed a large, solid, vividly red light travelling from west to east directly above Kadena AB, Okinawa, Japan. I could not make out the object itself, only the light which looked approximately 3 to 4 times larger than the size of Venus by the naked eye. There was no tail protruding or flicker to the light at all, just a steady bright red ball.The object was first noticed directly over head and I followed it until it disappeared over the clouds in the horizon. Total time in sight was maybe 4 seconds. I work on military aircraft and know of no aircraft that can fly that fast. Also there was no sonic boom or sound at all that night which I thought was even stranger.I am an Aircraft Structural Maintainer. Until now I have been a skeptic, but always open minded to the possibility of UFOs. I havent heard of this site until just a few days ago, figured I would post what I saw.
