I've never seen one of these before: a United States of American Gulfstream jet cut in front of a queue of about 10 aircraft. Listening to Channel 9, I heard the air traffic controller referring to it as "Gulfstream One" or "November One" interchangeably. It was likely no one particularly special -- perhaps a USAF or NASA flight or perhaps a high-ranking military official -- but it was the first time I had seen one up close.
