Just watched a fascinating interview with Pierre Sprey. His wiki page. He's one of the designers of the F-16. I've read before of problems with the F-35 program but here he savages the entire plane, not just the program behind it.
You have wonder if the F-35 (wiki) is in trouble when you have someone like war hawk "Bomb Bomb Iran" John Mcain quoted as saying the $398.6 billion program has major problems.
