On November 7th about a dozen United Airlines employees, including a few pilots, claim they saw an unusual disc-shaped object in the sky over O’Hare International Airport, Chicago. The witnesses insist that what they saw was not a terrestrial aircraft of any kind, that it was anywhere from 6-24 feet in diameter, and that after hovering for a few minutes it vanished at impossible speed through the clouds.
