A tire fell off a United Airlines Boeing 777 plane that had just departed from San Francisco International Airport and headed to Osaka, Japan. The tire landed in an employee parking lot, damaging multiple vehicles but causing no injuries. Video showed the tire spinning rapidly down and bouncing between cars. United confirmed the plane diverted safely to Los Angeles International Airport, where passengers will continue on to Osaka later. The remaining tires can handle the aircraft's weight. Aviation experts said loose tires are typically a maintenance issue rather than a design flaw. The FAA will investigate the incident.
