DENVER (AP) — A United Airlines jet returned safely to the Denver airport Tuesday after a bird was sucked into one of its engines shortly after takeoff. The engine that was struck continued to operate and the second engine wasn’t affected, airline spokeswoman Megan McCarthy said. A passenger said the bird hit the right engine. None of the 151 passengers and crew was injured. The Boeing 757 had just left for San Francisco when the bird strike happened. McCarthy said the pilot’s decision to return to the airport was a precaution.Contact the news staff at [email protected]
