A United Airlines flight from Denver landed safely in Washington, DC, after its crew reported an emergency because a male passenger began praying in the aisle. The plane was escorted by military jets after the crew declared the emergency, KUSA-TV reports, and landed 13 minutes ahead of schedule last night at Dulles International Airport. A United spokeswoman says the passenger wasn't following flight attendant instructions for landing; he was escorted off the plane by police. (More emergency landing stories.)
