Ekerold saw him flash past Igoa, thought: "That was close". Then he saw two instant explosions. The first was Igoa's fuel tank, as Sheene's Yamaha hit the fallen bike; the second was Sheene's tank, as his disintegrating motorcycle somersaulted down the track. Simultaneously, Middelburg also ran into the wreckage. Ekerold's trousers were torn by flying debris, probably the front forks, ripped off Sheene's bike. The severity was unimaginable.
Keith Huewen was close behind, just in time to see the explosions, slamming on brakes and riding blind through a pall of smoke. He emerged to a horrifying scene, 'like an air crash'. Debris and smoking wreckage was strewn across the track. He'd stopped by chance alongside Sheene whose body was also smoking. Huewen was sure he must be dead. Trembling with shock, he returned to the pits with the dreadful news. Franko heard immediately, and went straight to the scene. As he approached, he met a white-faced Ekerold, who told him: "Don't go, Franko. You don't want to see."
But Frank had to go. Kenny Roberts had arrived by then, and carefully removed Barry's helmet. Other riders were standing around, some in tears. Marie Armes, wife of an official and a nurse by profession, inserted a breathing tube down his throat, very probably saving his life. Then Franko arrived, knelt beside him, cradled his head, and spoke to him. "Barry. Listen son. You're alright. Speak to me."
Amazingly, Barry responded, a faint groan. Frank kept talking, willing him to consciousness.
