A plane flying from Rochester, New York to Washington-Dulles International Airport in Virginia turned around and landed again immediately after takeoff, when the pilot noticed a bomb threat written on a window shade.
"It was serious enough the pilot felt he should come back," said the Rochester airport's manager. "It was a precautionary move on the part of the pilot, but like everything else since September 11 it's going to be thoroughly investigated."
The plane was thoroughly searched and the passengers questioned by the police and the FBI, but nothing out of the ordinary was found. The plane continued on its way to Dulles four hours later.
