A Delta Air Lines flight was forced to make an emergency landing in Montana Saturday night after the plane's toilets stopped working.According to The Associated Press, the six-hour Delta flight was on a non-stop journey from New York City to Seattle when the bathrooms on the Boeing 757 ceased functioning, leaving passengers to say they could not hold it any longer.MORE Airlines & AirportsAs a result, the pilot called for an emergency landing and diverted the plane hundreds of miles south to Billings Logan International Airport. The flight landed safely at around 6 p.m. local time, but the ordeal wasn’t over yet.Unfortunately, no gates were available for the Delta flight and the plane had to taxi to a cargo area. Ground crews at the facility rolled a portable stairway to the aircraft and passengers were able to “disembark to find relief of built-up pressures,” according to an official statement from Delta.Billings airport director of aviation and transit Kevin Ploehn told the Billings Gazette the passengers waited inside a terminal while crews repaired the toilets, refueled the plane and prepared the flight for takeoff.READ MORE: BYOB Could Ground Your Next FlightWhile it doesn’t happen often due to broken bathrooms, Billings airport does deal with diverted planes occasionally.“I’ve heard of flights getting diverted, not here, because toilets overflowed and that blue water was rolling down the aisle,” Ploehn told the Billings Gazette. “That can’t be very pleasant.”Follow @Donald_Wood
