Some not so good news about the Charlie: Testing was halted back in November after a "small crack" was found in the titanium wing spar, which was downplayed at the time by JPO spokesperson Joe DellaVedova, "Such discoveries are expected during a developmental test program." Note that the JPO was more or less forced to respond to press reports about the cracks - the JPO had not released news of the casualty publicly. Testing resumed in February after repairs, but was halted 3 days later after strain gauges detected further cracking.
