Fat disc shape. 3 lights. One light was red. I think other 2 were green and white. Went in different directions and hoovered.9/3/16 1am. 11 mile and main area in Royal Oak MI. Craft coming at me (north) with white lights but stopped and went east and hoovered. Looked like a fat disc shape. 3 lights. One light was red. I think other 2 were green and white. Than went backwards (south) and hoovered. Than really fast to the right (west) and hoovered and than to the east again and hoovered and than to the west again really fast and I could hear a really shrill noise when it went fast to the west. It did a few of these left and right and back and forth moves and hoovered each time. I got my camera. Took pic off the porch but I had my finger on the flash which is a poor feature of this camera but maybe that's a good thing. Went to take second pic and it went behind trees and disappeared but I watched it for over 5 minutes. The picture just looks like a blur of gas since it was in motion. I would say it was the size of a jet and at jet altitude.
