A mixture of good and bad news, but I'd say (and I'm neutral on JSF overall) more bad than good:
Pentagon report cites "lack of maturity" of Lockheed F-35 jet - Yahoo! News UK
As I said many posts ago, don't underestimate the software issues involved in such a "software intense" aircraft.....
As for the process of overlapping development, production and testing, mad as cheese in terms of the customer obtaining aircraft with a decent functionality, and subsequent having to retro fit or scrap - but no doubt good for the company as they get some of the production money much earlier in the programme.
