NEWS Singapore Airlines is investigating how one of its jets suffered a loss of power in both engines and descended 13,000 feet

Singapore Airlines says it's investigating how one of its jets suffered a loss of power in both of its engines over the weekend and descended 13,000 feet—nearly 2.5 miles—before regaining altitude en route from Singapore to Shanghai. 

The Airbus A330-300 was carrying 182 passengers and 12 crew members at 39,000 feet when the incident occurred Saturday, the airline says in a statement. The jet lost power in both engines after hitting bad weather several hours into the flight, but one engine quickly resumed normal operations, according to the statement.
