350 billion dollars later.....Let me guess this jet was one of those "diversity projects."

The dogfight, which was staged in January near Edwards Air Force Base, California, was designed to test the F-35’s ability in close-range combat at 10,000 to 30,000 feet.

Both the F-35 pilot and the F-16 pilot were attempting to ‘shoot down’ the other.

But, according to the F-35 pilot’s report, which has only recently been made public, the jet performed so appallingly that he deemed it completely inappropriate for fighting other aircraft within visual range.
