Recently, according to media reports, the F-35 fighter jets purchased by the South Korean Air Force from the United States have been delivered in 2019. South Korea has used the F-35 fighter jets for more than two years. However, it is rumored that the use of F-35 fighter jets is strictly controlled by the U.S. military. Outsiders are not allowed to approach at will.
Even the startup password of the aircraft’s data system is changed every day. Every morning, the U.S. Air Force sends the password and the South Korean enters it to boot. If the system cannot be turned on, the entire aircraft cannot be started because the F-35 is too advanced and the internal dashboard of the aircraft And the operating system is basically a few large LCD screens and a small number of mechanical instruments, far more advanced than the Russian Su-27, which is full of mechanical instruments and manual buttons.
