A SWISS International Airlines flight heading to Washington from Zurich had to turn back over the Atlantic as half of the toilets stopped working.
The airline told the press that a blocked pipe shut down all the toilets on the left side of the Airbus A330, two hours into the flight.
The crew decided to turn back to Zurich.
Passengers had to wait at the airport for another 5 hours before they were able to take another plane.
