Meanwhile, environmentalists were voicing concern—about how noisy such aircraft are taking off, about the possibility that their high-altitude emissions would erode the ozone layer, and about how disruptive the sonic booms would be. Fourteen production aircraft were manufactured, but one was scrapped in 1994 and another crashed in 2000.).
