must be a HELL of a lot of good will behind this bird then
More than any other plane has ever had,apparently.
I do not know anyone with good insight. But, from my own experience, something like a Windows operating system mandatory update...things that used to work do not work any more. And it can take considerable work to find all of the issues. It sounds like F35 is mostly software issues. Hard to tell why there are issues, but I am seeing lots of Windows upgrade issues right now.
