SIOUX CITY, Iowa - A Denver-bound jetliner landed in Sioux City after its pilot noticed a power warning light flashing in the cockpit.
Southwest Airlines Flight 3809 landed without incident at 2:40 p.m. Sunday after leaving the Minneapolis-St. Paul airport about 90 minutes earlier. The Boeing 737 model carried 143 passengers and five crew members.
Southwest spokeswoman Michelle Agnew says the pilot took the cautious route even though the situation wasn't dire. Agnew says the system that was involved powered such features as coffee pots and cabin lights and that backup power sources were available.
Sioux City airport operations manager John Backer says the passengers waited in the terminal for about three hours until a replacement plane arrived and they could board and resume their journeys.
