Two opposing views.
1. The aircraft is great! http://www.bbc.co.uk/news/uk-10648250
2. The aircraft is a POS! http://www.pogo.org/resources/nation...29.html#report
On the second report, be sure to scroll down to the POGO report and read the highlighted parts.
BTW here is a quote from yet another (unknown) source:
When the Joint Strike Fighter team told Guy Norris about the jet's first run to its Mach 1.6 design speed, a couple of minor facts slipped their minds. Nobody remembered that the jet had landed (from either that sortie or another run to Mach 1.6) with "peeling and bubbling" of coatings on the horizontal tails and damage to engine thermal panels. Or that the entire test force was subsequently limited to Mach 1.0.
But selective amnesia is not even one of five "major consequence" problems that have already surfaced with the JSF and are disclosed by a top-level Pentagon review obtained by Ares. Those issues affect flight safety, the basic cockpit design, the carrier suitability of the F-35C and other aspects of the program have been identified, and no fixes have been demonstrated yet. Three more "major consequence" problems are "likely" to emerge during tests, including high buffet loads and airframe fatigue.
