A flight carrying 50 people from Detroit to Rochester, N.Y., has landed safely after a sensor indicated that a fire extinguisher in the plane's cargo bay went off.
Authorities say Northwest Airlines Flight 2903 was about 30 miles outside of Rochester on approach Sunday night when an indicator alerted the crew of a possible problem in the cargo hold.
The flight was being operated by Memphis, Tenn.-based Pinnacle Airlines Inc.
Company spokesman Joe Williams says it's unclear whether the extinguisher went off or whether the indicator is faulty.
Greater Rochester International Airport Director David Damelio says the plane landed a few minutes ahead of schedule. He says there was no fire or smoke in the cargo hold.
