The majority of California residents live in areas that do not meet permissible air quality levels for regulated air pollutants—mostly due to exceedances in atmospheric concentrations of ozone and particulate matter. Vehicles that are engine certified include incomplete gasoline vehicles and those powered with diesel engines.

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. The last of these issues was perhaps the most vexing, prompting the U.S. Boom Supersonic.
