Engine Trouble Forces Jet Back to SFO

On Friday night, an engine on United flight #158, bound for Chicago, stalled in-flight forcing the plane to operate on the one remaining engine. Shortly thereafter, the pilot turned the plane around and landed about 30 minutes after takeoff. Reports from passengers stated smoke had entered the cabin while in the air. A United press release however asserts the smoke occurred only after the plane safely returned to the gate and engine turned off. No injuries were reported.
