Toilet torture in the Dreamliner: Boeing makes a confused flight and lands back at the start after six hours. Boeing 787-10 made a U-turn over Greenland and returned to Amsterdam.
The toilets on flight KL-601 first malfunctioned, then worked again and finally didn't work. The airline KLM confirmed the incident to the flight portal. There is no information as to why the Boeing's toilets failed. It's entirely possible that the passengers themselves could have contributed to the toilet problems. Airplane toilets can become clogged when foreign objects such as paper towels are thrown in.
