Officials say a Delta Air Lines flight from Minneapolis made an emergency landing in Las Vegas on Thursday with the co-pilot at the controls after the pilot was locked out of the cockpit.

McCarran International Airport spokeswoman Christine Crews says none of the 168 people aboard Delta flight 1651 was injured, and the MD-90 aircraft wasn't damaged.

The plane had been headed for Las Vegas, and it pulled into its regular gate at McCarran on time about 12:30 p.m.

Delta spokeswoman Lindsay McDuff says commercial aircraft can be landed with one pilot, and Delta crews are trained for such situations.

Crews says the door malfunctioned, and McDuff says it'll be evaluated by maintenance technicians.

Crews says the emergency was declared 13 minutes before the plane touched down at 12:23 p.m.
