I witnessed a square object soaring through the sky (in front of my car). It had 4 lights -- one mustard-yellow light on each corner.

It was dark and I was driving home from work and was almost home when a strange object in the sky dipped down just ahead of my car and then gracefully soared upward and through the tree tops.  As it went through the tree tops in turned sideways at an angle and then straightened out after going through the trees and disappeared behind the trees.  It was the shape of a SQUARE with 4 mustard-yellow lights (one light on each corner) that were very bright.   When I first saw it I was almost to the stop sign near my home so I stopped and watched it until I could no longer see it.  My first reaction was “what the heck is that!”  It was so close to me that it shook me up.  I can’t stop thinking about it.
 It’s hard to say how big it actually was, but I can tell you that it looked like at least a 50’ to 60’ square.  I had my car windows down on both sides and even stuck my head out the window and could not hear any sound whatsoever.   It moved so gracefully through the sky. It was a strange sight to see, certainly not the ordinary.
