United plane loses wheel on takeoff from San Francisco. The plane with around 250 people on board landed a little later in Los Angeles - instead of Japan.
The incident is part of a series of mishaps for the Boeing 777. In January, a Boeing 757 lost a wheel shortly before takeoff from Atlanta and in February an Airbus A319 had to land in Brazil with a missing tire. The company is currently increasingly in the spotlight after a virtually new 737-9 Max aircraft lost a part of its fuselage.
