I was smoking a cigarette and looking at airplanes through my binoculars when i noticed this craft rapidly flying from the south to the north, it was lit but had no red and green lights on it, i could hear the airplanes engine noise but this craft made no sound. i have been seeing aircraft's like this maybe once a month or longer. last night i saw 2 crafts like the one that i just saw a few minutes ago. i continued watching the object until it was out of sight.
