Pilots see UFO over O'Hare Airport in Chicago
Of course, pilots don't know what they're looking at, even though there were multiple witnesses. The public relations department just said they were looking at light reflecting off a low cloud cover. Just remember these very same pilots are the ones who fly around the world under adverse conditions and get you there safely. I would think they know a piece of hardware such as a disk, when they see it as they are <trained to do.>
