The F16 fighter jets were not just some ordinary jets that Jin's original world was used to. These prototypes were similar to the Sherman Tanks where he had changed the interface inside so that people driving it would not need years of knowledge to do so. It was the same for the F16s where the interface had been simplified and the artificial intelligence engine that Jin had created along with the vehicle was powerful enough to work along with non mages.
However, despite it being piloted by people with little to no magical powers, they were still equipped with items that would be useful if the people using it had some basic form of mana. For the Sherman Tanks, the tank driver needed just a little be of mana to activate a dimension storage unit within the tank that connected the tank to a 'universal' warehouse where all the shells were kept.
