A BRITISH Airways flight has been forced to turn around following the discovery of a “smelly poo” in one of its toilets.

The flight was en route from London to Dubai, and had been in the air for 30 minutes when the odour became “unbearable”, the Mirror reports. Crew members were unable to fix the problem, and the plane had to return to Heathrow Airport for health and safety reasons.

Insane! Our BA flight to Dubai returned back to Heathrow because of a smelly poo in the toilet! 15hrs until next flight... #britishairways — Abhishek Sachdev (@CllrAbhiSach) March 12, 2015

“(The pilot) said you may have noticed there’s quite a pungent smell coming from one of the toilets,” Abhishek Sachdev, a passenger on the flight, told the Mail Online.

“He said it was liquid faecal excrement, those are the words he used.”

Lovely. The plane’s passengers disembarked in London, and had to wait 15 hours for another flight.

“We’re very sorry for the discomfort to our customers,” a British Airways spokesperson told the Welwyn Hatfield Times.

“We provided them with hotel accommodation and rescheduled the flight to depart the following day’s lunchtime on an alternative aircraft.”
