A cabdriver was in a coma after his taxi was flung into Rio de Janeiro's Guanabara Bay by the jet blast of a Vasp 737 preparing to depart from the city's Santos Dumont airport. Leoncio Ribeiro, director of a taxi cooperative where the 64-year-old victim works, said Wednesday's accident, in his view, was caused by badly placed warning signs and traffic lights. "The signs that tell you to stop when the plane is on the runway are practically invisible. When Antonio Macedo, who is a very experienced driver, drove to the runway the plane was already there, preparing to take off," He said the route behind the runway was the only road to the place where Macedo had taken a client. He was returning alone. "The car flew at least 25 metres (yards), spinning in the air, and hit the rocks at the Guanabara bay coast. The driver was thrown out of the car and fell on the rocks. He has a broken skull and thorax, and is in a coma," he said. The car was destroyed. Authorities said the signs were in perfect order and blamed the driver, according to the local press.
