Smoke prompts emergency evacuation of Alaska Airlines plane

For the second time in three months, smoke in the cabin has forced the evacuation of an Alaska Airlines MD-80.

An airline spokeswoman says 140 passengers and five crew members used emergency slides to get out right after the plane landed in Long Beach, California, Sunday evening.

Caroline Boren says the crew considered the smoke thick enough to merit an emergency evacuation of the flight that had just arrived from Seattle.

Boren says paramedics treated two passengers and a flight attendant at the airport, and one passenger was taken to a hospital for what appeared to be minor injuries.

Another MD-80 was evacuated after landing in San Francisco in May.

Federal investigators have been called in.
