Qantas A388 near Los Angeles on Jul 2nd 2014, rain in cabin

A Qantas Airbus A380-800, registration VH-OQD performing flight QF-94 (dep Jul 1st) from Los Angeles,CA (USA) to Melbourne,VI (Australia), was enroute at FL320 about 30 minutes into the Pacific crossing when the crew decided to return to Los Angeles after a water pipe in the upper deck had ruptured causing water to rain into the lower deck "showering" about 80 people in the economy class. The aircraft landed safely back in Los Angeles about 75 minutes after turning around.

Passengers reported the "rain in the cabin" began about half an hour into the flight and the aisle became flooded. Galleys and inflight entertainment systems were shut down. About 45 minutes later the crew decided to return to Los Angeles.

The airline reported the passengers were relocated into dry areas of the aircraft and provided with blankets. The crew decided to return to Los Angeles for passenger comfort, all other aircraft systems are well protected and were not affected.

A passenger tweeted: "Who says it can't rain inside a plane? My Qantas travels never disappoint."
