> This and aircraft's other notable performance characteristics are made possible in large part due to its highly aerodynamic overall laminar flow shape, which produces approximately 59 percent less drag than existing similar-sized, more conventionally-shaped aircraft. Wait, if the shape is that much more efficient, why don't we already see this sort of shape for commercial jets? Are there other compromises involved?
