Overall this is a pretty good article that avoids most of the misinformation that tends to be propagated whenever the F-35 comes up.

However, calling the F-35 the "most expensive weapon ever built" is extremely misleading. This video explains it better than I ever could: https://www.youtube.com/watch?v=LyHlp7tJrxY&feature=youtu.be... ("F-35 Lightning II: Busting Myths - Episode 2").

The entire video series is well worth a watch if you have any interest at all in the subject.
