1) The F-35 has VASTLY more software and several software systems that the F-16 and F-22 didn&#x27;t have.<p>2) The F-22 software was largely written in Ada, a sane language that&#x27;s great for real-time systems that cannot fail. Apparently the F-35 software is mostly written in... C++. Writing fault-tolerant real-time C++ is like walking on a tightrope while gripping a gun with the safety off. You can do it, but it&#x27;s not particularly pleasant.<p>3) Apparently the team was considerably expanded&#x2F;replaced between the F-22 and F-35.
