Walking out to the car in the morning (4:50am). I was shocked to see a small, black, isocoles shaped triangle craft, "floating" from NE to NW above my house, no more than 150 ft off the ground. The craft was skimming the treetops. Maybe was moving at 40mph, I felt like it was too slow for a jet or prop plane to cruise. I saw no exhaust outlets, no propellers, no symbols, no windows. The triangular craft was a black color that was very hard to see. It did have airplane like lights on the corners. small blinking green light on the left rear corner. Small blinking red light on the right rear corner. A small constantly on white light was on the forward tip. The craft cruised by - silently - from my right to my left just above the treetops near my house. It was in my sight around 1-3 minutes until I could no longer see it in the distance. The craft was very small. At first I thought it was only 15 ft from front to end, but now I think It was slightly higher and larger. Maybe 30 feet from tip to end, 15 feet across the rear edge. No lights or engines or glow was seen on the rear end. Was it a drone? If so it was like a strange shaped balloon with unknown means of propultion. Why was it displaying airplane/ heliocopter like lights but flying so low to the ground as to not be seen? If this was military, they some type of hover silently technology. I don't even want to consider that it was alien because the thought scares me.
