Pentagon F-35 chief sees progress, but affordability still focus

U.S. Air Force Lieutenant General Christopher Bogdan told a defence conference that he'd reached his quota for "juicy, controversial, headline-making quotes" for the month after lashing the plane's manufacturer Lockheed Martin Corp and engine maker Pratt & Whitney during an air show in Australia.
