A bungee instructor has revealed that a terrified woman backed out of her jump just moments before his colleagues hurled a woman off the bridge to her death without a safety rope.Maria Eduarda Rodrigues de Freitas, 21, was seen in disturbing footage circulating online being thrown by three men from the Skeleton Bridge in Limeira, São Paulo, on Saturday and falling to her death.Now, an instructor, named Gustavo, who told local media that he had been attending to another customer at the time of the fatal jump, revealed that another woman, before Maria, had changed her mind about taking the leap.'I was four meters away from where the platform is. I had my back to the jumping platform because I was equipping another client. [Maria Eduarda's jump] was the first. Before her, there was supposed to be another one, but the girl got scared and gave up,' he said.The young woman was seen in horrific footage of the incident, kitted out in a helmet and body harness, but a long pile of rope could be seen unattached on the floor beside instructors from the company Entre Cordas. Gustavo said that he had initially put the bungee equipment on Maria, but when it got to the actual jump, another group of instructors were responsible for attaching the safety rope and checking if the equipment had been properly secured.On Saturday, Maria, an aspiring physical education teacher, had asked to be launched 130ft from the abandoned bridge 'aeroplane style', with three instructors hoisting her above their shoulders as she spread out her arms. Recalling the moment she was tossed off the bridge, Gustavo told reporters how he heard Maria's screams, but hadn't realised the gravity of the fall until she had already hit the ground.
