Heh so your theory is that someone took over the cockpit, entered the waypoint in to the FMS, then hung around for half a day or so watching the rest of the instruments they presumably couldn't read, then when the egg timer went off and they didn't see China, they said "damn, guess we'd better crash". That's inspired! I swear with the talent I've seen in this thread, someone should open "PPrune detective services", Seriously, we are sitting on a gold mine here, people!
