An airliner has made an emergency landing in the United States after a gaping hole in the roof caused a sudden drop in cabin pressure.
Southwest Airlines flight 182 from Phoenix to Sacramento put down safely at a military air base in Arizona.
Passengers heard a bang as the roof panel blew open in the cabin. "You can see completely outside," one woman told the Associated Press news agency.
