a 2 to 3 foot long object seen in allentown, pa

myself and a sales representative were leaving a Saturday shift at 12 oclock we opened wentdoor to leave.when this bright light above us shined as bright as a welding arc.It decended between the 2 buildings in which we were standing into a wooded area with the light dimming as it approached the trees We decided to go to the location we thought it might be.So we decided to approach the wooded area from the opposite side of the building.There was a road that went to a tree line.We had a hard time seeing it a first because it was well hidden because it blended right in with the trees. It was dark in color and was shaped like a cigar with some kind of extension from it. It reminded me of a miniature submarine. As we watched it it hovered like a helicopter and appeared to yaw left and right. it seemed to be inside a heat bubble which made it hard to see. We watched it for about 20 minutes at the tree line.So we decided to go back to the front of the building where we first seen it.I visually scanned the area from the original location and couldn't see anything until I scanned the sky. There it was a 1000 ft. or so up in the air.It appeared to leave cloudy misty effect around. After watching this thing whatever it was for about 45 minutes we decided to leave. Now whatever these things are they could be in you back yard without you knowing about it. There was no sound what so ever. While it was at the tree line it didn't leave until we did. Now here's the kicker!! I'll take a lie detector test to prove my story any day of the week. " IT WASN'T MY FIRST ENCOUNTER " !!!
