It was appx. around 10:00 p.m.,when I was walking around the side of my friends apartment building,looked up and noticed the craft.I didnt know what to make of the object.The lights were very bright,and the colors of the lights were different than any color I'd ever seen before.When I first seen the object I thought that it was an airplane,but it didnt move or make a sound.The object was triangular in shape,that being with wide angles.Bright colored lights,motionless and soundless.I watched it for appx. 5 minutes,then went in to take my friends out to see the object,and it was no longer there.I then called the airport to see if they had any idea what it was,which they didnt.I also called the police dept.,they also had no reports of any such thing,of course no one believed me.Have there been any other incidents similar to this one?
