As a newbie to this forum, it is difficult to know if something has previously been posted. I have used the forum search and did not find anything relating to this topic but as I have learned on other forums, that does not necessarily mean anything. So here goes:
Tom Pryce was an F1 driver from Ruthin, Wales, in fact the only Welsh drive ever to lead an F1 champoinship Grand Prix, he also claimed two podium finishes in his short (42 races) career.
At the Kyalami Circuit for the South African Grand Prix on March 5, 1977, Pryce was trying to fight his way back into contention after a terrible start. On the 21st lap driver Renzo Zorzi (Pryce's Shadow Racing teamate) was experiencing fuel problems wherein fuel was pumping directly onto the engine (as it is oft times wont to do). Zorzi pulled off on the left side of the track on the main straightaway, just beyond the brow of a hill. Two race marshalls ran across the track to help, one of them being 19-year old Frederick Jansen Van Vuuren who was also carrying a 40-lb fire extinguisher. Driver Hans Stuck barely missed the first marshall, Pryce, driving behind Stuck, struck young Mr. Van Vuuren at a speed of approximately 170 mph, killing him instantly. The fire extinguisher Mr. Van Vuuren was carrying hit Pryce in the head killing him likely just as instantly.
If you wish, you can watch a rather disturbing video of the accident on YouTube .
Again my apologies if this has been posted previously.
