A United Airlines flight departing from San Francisco experienced a mishap as it took off, losing one of its tires that fell onto parked cars at SFO Airport. The Boeing 777, en route to LAX with 249 passengers, saw its landing gear retract, causing a tire to detach. Fortunately, there were no injuries on the ground, but damage occurred to some vehicles. The plane landed safely at LAX, and United transferred passengers to a different aircraft for the onward flight to Osaka. While the incident didn't result in casualties, it adds to recent concerns about Boeing aircraft, following other safety-related incidents.
