We saw what appeared to be five or six craft, moving fast and changing color.Myself and two friends were outside, in my backyard smoking cigarettes. We were not intoxicated or under the influence of any form of inhibiting substance. One of my friends was looking at the night sky, and told us to run over as quickly as possible. She pointed upwards, and pointed out five, possibly six bright yellowish lights flying in a tight formation. I thought they might be military craft, but as they flew, one of the lights turned a dark red, almost crimson color, and darted off at a ninety degree angle, flanking it's fellow craft and passing to the rear. The other craft split up and circled in violent turns to rally on the first ships rear. One of my friends reported hearing a sound, but that is unconfirmed, as neither my other friend or myself heard this sound. Suddenly, they broke fast and vanished. I know for a fact that no craft currently in use by any military force on this planet can manevuer like that. After the event, we ran inside to get a camera, and waited outside for quite some time, but nothing happened after that. I have reported a somewhat similiar occurance in the same neighborhood quite some time ago, and I have heard rumors from this area that sightings have occured in the past five or six years. Please DO NOT contact me via mail or telephone, but rather e-mail. Other people I live with are extremely skeptical, as was I before the first of these occurances happened.
