Sen. Graham's plane forced to turn back after engine sounds

      GREENVILLE, S.C. (WCIV) -- Sen. Lindsey Graham's flight to Washington from Greenville never made it Monday afternoon.

      According to the senator's Twitter account, the plane took off and then made an emergency landing after passengers noticed a strange sound coming from the engine.

      Graham tweeted that shortly after that, the pilot declared an emergency and returned to Greenville.

      Airport spokesman Rosylin Weston said the plane landed back safely around 3 p.m. Monday. The aircraft had 40 people on board. The plane had to turn back to the Greenville-Spartanburg International Airport because a warning light came on in the cockpit.

      His office said Graham was headed to Charlotte to catch a different flight to Washington.

      "We safely returned with fire trucks and first responders at the ready," Graham tweeted. "Thank you to the first responders at GSP and flight crew for the work you do."
