Looks like the FAA has some more damage control to do. A United Airlines pilot has been arrested at London's Heathrow Airport on charges that he was drunk. Erwin Washington, a 51-year-old pilot from Colorado, had exceeded the legal alcohol limit, and authorities detained him before he had a chance to take off for Chicago. The flight was subsequently canceled, and the 124 passengers aboard were diverted to alternate flights. United Airlines said it is conducting a full-scale investigation.
