SAN FRANCISCO (AP) - A Chicago-bound United Airlines flight was forced to return to San Francisco International Airport early Saturday after running into engine trouble.
UAL spokeswoman Robin Urbanksi says United flight 158 landed safely at SFO about 30 minutes after takeoff after one of its engine compressors stalled.
The pilot was able to turn the plane around and return to the airport, flying on the aircraft's second engine.
Urbanski says smoke came into the cabin after the plane landed and the engines were shut down. The airline is investigating the source of the smoke, but says no one was injured during the incident.
The airline provided overnight accomodation to the passengers and arranged flights for them Saturday.
