There was an hijack on a UPS cargo plane a number of years back by a
disgruntled UPS employee.  He overpowered the skeleton flight crew and
attempted to crash the plane into the main UPS hub in Memphis, TN.
Fortunately, the injured flight crew struggled back control of the plane
and overted a potential disaster.

  In fact, I don't know of any previous
hijacking scenario where the whole point
 was to fly the plane into something to destroy it, rather then to take the
 plane somewhere other then the intended destination; hijackings do take place
 all the time in other parts of the world, though, so it might happen and I
 just don't know about it.  Anyone else have any idea? 
 In between (i.e, no specific destination, but a crash was desired)
 ...a man tried to hijack and crash a plane here in California
 a couple of years ago (IIRC, the flight was from Southern California up to
 Northern California).  The cockpit crew overpowered
 him, and landed safely.  IIRC, the criminal venue was in San Francisco, and the
 defense attorney tried to get bail for the client, on the grounds that he had
 been mentally disturbed before, but was now "okay".  (Don't recall what
 happened.)
