WINDSOR LOCKS, Conn. — This was a pig that truly could not fly.

The pig was ordered off a US Airways plane at Bradley International Airport in Connecticut on Wednesday after crewmembers determined the animal had become disruptive, said Laura Masvidal, a spokeswoman for US Airways parent American Airlines said Friday.

The pig had been brought aboard the flight by a passenger as an emotional support animal, Masvidal said. She said both the pig and its owner left the aircraft before it took off. She had no other details and did not immediately know where the flight was headed.
