According to the Air Force Times, the Air Force has reported that a manned QF-4 crash in July was caused by a flight control malfunction.  A stab actuator disconnected and caused an uncommanded, and uncontrollable, pitch up.

The article notes the $2.4 million Vietnam-era aircraft was lost.  It also includes a write up on the crash of a Predator in June.  The small, unmanned prop-driven plane was valued at $4.4 million, or nearly twice the drone-duty F-4.

In another story, the AF Times said a Wisconsin ANG F-16 lost in June crashed due to an engine malfunction.
