#9 Chicago O'Hare Incident

In 2006 several United Airlines employees reported seeing an unidentified object in the sky. The object, which was reported to be saucer shaped, punched a large hole in a cloud as it rose back up into the sky. The hole remained visible for quite a while, but the FAA did not investigate.
