What was one of the focuses of the Vision 100 - Century of Aviation Reauthorization Act of 2003?

The Vision 100 - Century of Aviation Reauthorization Act of 2003 primarily focuses on the endorsement and support of the Next Generation Air Transportation System (NextGen). This initiative aims to modernize the air traffic control system by implementing advanced technologies and procedures to address the growing demands of air travel. The NextGen system is intended to enhance safety, increase efficiency, and reduce delays in the national airspace. By prioritizing this overhaul of the air transportation infrastructure, the Act reflects a commitment to improving the aviation industry in the 21st century, ensuring it can accommodate future growth in air traffic while maintaining a high level of service and safety.

Other options, such as the expansion of military air bases or creating a new aviation taxation system, are not central to the goals outlined in the Vision 100 Act, which focuses more on the modernization and enhancement of civil aviation capabilities. While commercial space transportation regulations are relevant to aviation, they were not a key focus of this specific legislation.
