HH,
Errr, actually, F-35 was ordered on 26 October 2001. First flight was on 15 December 2006. So, took 5 years to fly and 11 years after being ordered is 21 percent through flight test.
I absolutely agree that the programme has suffered serious delays, and yes, software and mission systems testing is the big 'elephant in the room'. But, let's at least get the pig the right size before choosing the lipstick.
Best Regards
