RTO -- Nav launched into Throttles

Here's another odd sort of people-in-cockpit distraction-interference:

Air France 272 / 27Jul61 B707-328 F-BHSA T/O accident at Hamburg Germany. [Directional control, Rudder, RTO, rwy excursion.] T/O Rwy 23 (2923m long x 45 m wide), wind 280/18G28; EPR set, slight left rudder-pedal to compensate for wind wx-vaning, speed increase left-pedal decreasing, (F/O held right wheel and some fwd yoke), between 100-120 KIAS a/c veered left, Capt used rudder to regain control but felt rudder was difficult to move; then at 120-130 KIAS a/c again veered left, Capt corrected the directional deviation but pedal resistance increased; yaw left then persisted, right pedal would not move (jammed) [F/E noted hydraulic pressure fell quickly); Captain initiated a rejected T/O, Throttles to Idle, used Reverse Thrust on #3 and #4 and right Brakes (directional control). NLG wheels left skid-marks equating to NW displaced 35 deg angle to Right (but Capt said he did not use NWS). Both Nose Wheels broke away, A/C yaw left persisted, all engine to Reverse Thrust, Brakes, Navigator was flung into the Pedestal-Throttles when NLG-wheels broke away (knocking throttles from Rev Thrust). A/C departed rwy after 2360 m of roll, in a gentle curve to the left; NLG broke, left MLG, then right MLG broke away. Fuselage broke into three sections (two circumferential fractures, one aft of cockpit and another fwd of wing LE). \\ Rudder examined, nothing abnormal found. ... Nav's tumble into Throttle-Reversers added to control problems, Nav had unfastened safety belt during T/O roll in an effort to get a better view as pilot encountered directional control anomalies. ...
