That sounds like a cover story for her selling access to government systems to me. The dog didn't eat the F-35 plans, the Chinese hacked the system - while all the while the access they gained or the plans they got were via the diplomatic pouch while she was Secretary of State and her husband was collecting speaking fees.
Bill was President, she was First Lady, Leon Panetta was White House chief-of-staff, and Gary Locke, who has family ties in China, was a Democratic campaign contribution bundler back in the 90's when the Clinton administration arranged the sale of U.S. long range missile guidance technology to China.

Deception - How Clinton Sold Out America To The Chinese Military by Charles R Smith.
Hillary Clinton was Secretary of State, Leon Panetta was Secretary of Defense, and Gary Locke was the U.S. Ambassador to China when they got the plans for the F-35. So did they hack the government contractor's system or did they get the plans or system access via the diplomatic pouch?
Gary Locke was still the U.S. Ambassador to China when the Chinese got into the U.S. Office of Personnel Management computer and pilfered data for a year or better.
That's way too much coincidence to be believable. Lord only knows what else they've sold. A back door to the NSA maybe?
So Hillary says, Yep, it's those dang Chinese hackers.
