UFO Sighting in Milwaukie, Oregon on September 19th 2015 – Three flashing lights hovering over my neighbor hood then took off slowly after about 10 minutes.

My wife and I took a walk around our neighbor hood and on the way back I seen flashing lights in the sky 3 difrent ones and while we where observing them you could see plains flying by and could tell that it wasn't any known aircraft I took a video of the three hovering then we continued to walk back home noticing them the whole way then one of them took off slowly and I took another video of it heading north. After taking the video looked back to see the other ones and they where gone.
