Some people were bouncing off the ceiling who didn t have their seatbelts on, said Alvin Cormier. And it looked like the two stewardesses in the back who were preparing for the end of the flight kind of fell on top of each other.
Two flight attendants and one passenger were taken to the hospital with minor injuries.
TSA officials reported some sort of customer service disturbance on the flight.
The crew of flight 1437 requested law enforcement officials meet the aircraft upon arriving in Houston, from Washington D.C., because of two disruptive passengers. Law enforcement met the flight and other customers deplaned normally, a United Airlines spokesperson said via email.
