Low speed on approach, go-around initiated, rather than speed recovery. Pitch up uncontrollable, 737, basically run out of elevator. Like this one:-
Report: Thomsonfly B733 at Bournemouth on Sep 23rd 2007, disconnected autothrottle on approach results in 44 degrees pitch up
Another option is blocked pitot, as you descend speed appears to drop, so you push forward to increase speed. Alternatively instrument failure of PFD, like this in 1999:-
