Nov. 8, 2009 (United Press International) -- Smoke and reports of flames caused a Delta (NYSE:DAL) Air Lines plane to be evacuated before takeoff from Atlanta, a Delta official said.

The right engine on Flight 1016, bound for Philadelphia, emitted smoke on Saturday, forcing the evacuation of the 138 passengers onto the taxiway, Carlos Santos, Delta spokesman, said, the Atlanta Journal-Constitution reported.

The cause of the engine smoke was still being investigated, the newspaper said.

No injuries were reported.

All passengers were reassigned to other flights to Philadelphia, the newspaper said.
