Delta Air Lines says fluid dripping onto a power unit created the smoke that forced passengers to evacuate a plane after it landed at Denver's airport.
After flight 1854 from Detroit landed normally Tuesday night, passengers reported that smoke filled the cabin as the MD-90 aircraft was taxiing to the gate. Delta says the plane stopped and its 146 passengers used the plane's slides and over-wing exits to escape the cabin.
Airline spokeswoman Lisa Hellerstedt said Wednesday that a small amount of hydraulic fluid dripped onto a hot power unit, creating the smoke that was blown into the cabin.
Investigators did not find any evidence of a fire on the plane.
