U.S. senator's plane makes emergency landing, all safe WASHINGTON (Reuters) - A United Airlines flight carrying U.S. Senator Lindsey Graham was forced to make an emergency landing at a South Carolina airport on Monday shortly after taking off on a flight to Washington, but all the passengers were safe, the lawmaker said. The Republican senator said he and other passengers noticed the aircraft's engine making a strange sound about five minutes after takeoff from Greenville-Spartanburg International Airport. "Not long afterwards, the pilot declared an emergency and we headed back to the airport," Graham said on the Twitter social media service. He said fire trucks and other emergency crews were at the ready when the flight landed. The Greenville News reported on its website that the United Flight to Washington's Dulles International Airport was carrying 40 passengers, including Graham, and that the pilot had noted an oil indicator light.
