HAMPTON, VIRGINIA -- Civil aeronautics is in the midst of becoming a “mature” industry, with all the drawbacks that this entails. For decades, technological advances have been essentially incremental, and the industry remains largely based on long-haul transport aircraft, with an emerging small jet component and a legacy of general aviation markets and products.
