I was siting on my front porch smoking a cigarette. I had just put down my children for the night. I heard the dryer inside going and was scrolling through Facebook. I looked up from the screen to see what I thought was a plane getting ready to land at Frederick airport, which is about 20 miles away. But I noticed it didnt move and the light on it was getting brighter. Now it was probably a good 2-3 miles from the house. It looked like a star. It shot straight up. Then without a sound it wizzed above and past my house. As it past and got closer. I noticed it was triangular in shape and black but had three round lights on the bottom. The closer it got the bigger it looked. I would say at a whole the ship was the size of a jet plane. But a full black triangle. And the round lights where probably a good 4-5 feet in diameter. It was very quiet. I heard a slight hum as it passed over me. I've been wanting to tell someone but didn't want to sound crazy. I don't know what it was. But it definitely sent me inside for the night.
