I was working a midnight shift at a local factory when i snuck outside for a smoke at the front of the building. it was approx 5 am -still dark with scattered cloud cover. as usual i was checking out the stars while having my smoke when i looked straight up and saw a very large black triangle shape(sort of like a billiard rack). it was solid with what looked like an uneven surface on the sides.The center had a dim red globe type light and near the corners were dim whitish lights.There was absolutely no sound other than distant auto traffic. the vehicle was very close and low flying and very large(larger than the factory). it moved in a northeast direction--very very slowly.I starred at it for the whole time i had a smoke.It slowly disappeared into the distance.I shook my head for the rest of the shift wondering if i really saw what i saw---and still do.I told no one at work.I wish i could go under hypnosis so i could really remember it better.
