Chicago Lights

In 2006, at the O'Hare International Airport, several distinct lights were seen above, airport officials and pilots could not identify the objects and there was no flights scheduled for that evening. If you notice in the video the objects looked as though particles were coming off of them, perhaps some type of propulsion, maybe the ships were damaged, or possibly they were meteors, either way its a phenomenon, and it should be speculated on and further investigated.
