A passenger on board the jet sent pictures to FOX 2. A United Airlines spokesperson says it happened just before 6:45pm on board a GoJet Airlines flight 3702. The jet was operating as a United Express flight.
The spokesperson says the jet had already landed safely and was taxiing to the gate when the nose gear somehow ran off the taxiway and became stuck in the mud.
There were 60 passengers and four crew members on board the flight. Buses were used to take those people to the terminal. Officials say the jet has been removed from the mud and GoJet officials are examining it.
The flight was coming into St. Louis from O'Hare Airport in Chicago. The plane was an hour and a half late arriving in St. Louis.
