My wife and i live in the 12th floor of high rise facing se. going to bed at 11pm and noticed a bright light in the direction of the grand rapids/kalamazoo airport. thought it was plane at first except after some observation noticed lights pulsating and alternating off and on plus small blue lights along with red strobers. too many lights for an airliner and also stationary. grabbed my nikon p900 and zoomed in getting almost 1 minute of video. the object simply faded away. my wife observed with unaided eye and only saw pulsating different color lights.
