Just to throw it out there:
Farnborough Airshow 2014 - the was to F-35 attended... but didn't due to safety inspections.http://www.bbc.co.uk/news/business-28321023
The X-35's maiden flight was 2000. The F-35's was 2006. Five and a half years later, the plane is still regarded as 'unsafe'. The F-35C is now scheduled for a 2019 introduction at the earliest; the other two models optimistically for next year. These dates have only been pushed back so far. The total program cost is now estimated to reach over $1,000,000,000,000. Unit cost is at least $125,000,000. The aircraft is untested, currently regarded as unfit to even fly and far in excess of the original costs; unit cost alone quoted for Canada and Australia has now more than doubled. It can't carry a reasonable payload without compromising its stealth, potential fundamental software flaws raised by programmers on the project have resulted in them being reassigned and the conflict the F-35 has been built for is extremely unlikely to happen; current events in Iraq and Ukraine have shown that air superiority is meaningless when your foe refuses to fight you on open ground. And Lockheed-Martin is still vigorously promoting it.
Lockheed-Martin and affiliates are, to put it politely, 'extracting the urine'.
