Disk shaped object hovering in the sky.I was walking northbound on 32nd avenue and looked up in the sky and saw something disk shaped that was hovering. It was the size of 3 jumbo size airplanes. It was the same altitude that the airlines fly. When it tilted towards me and I saw the metallic surface then it shot northbound out of sight like lightning. There were no clouds in the sky around it. Later I saw an Alaska Airlines plane fly by in the general area and it looked tiny in comparison to the disk shaped object.
