A Continental Express flight bound for Newark returned to the terminal at the Buffalo Niagara International Airport late this afternoon after a smell of smoke was reported aboard the plane. None of the 50 passengers or three crew member was injured.

An alert was sounded at the airport at 4:45 p.m. shortly after Continental Flight 4191 pushed off the gate and was taxiing for take-off, according to C. Douglas Hartmayer, spokesman for the Niagara Frontier Transportation Authority.

The captain of the flight returned the CRJ aircraft to the terminal, lowered the stairs and the passengers and crew successfully evacuated toward the terminal, Hartmayer said.

The source of the smell of smoke was not immediately determined. An investigation was continuing.
