In another incident involving a Boeing jet, an Osaka-bound flight of United Airlines, that took off from San Francisco Airport in the US, had its wheel drop off from the flight, as it took off from the runway. The wheel that fell off the flight is reported to have landed in a car staff parking facility, damaging a car in the process. The flight involved was a Boeing 777. This is another incident which highlights the conundrum that of the biggest companies, and one of the largest exporters in the US is facing. The company's stock-gain driven model of revenue generation and investor satisfaction has often been questioned.
