How Elon Musk Can Bring Air Traffic Under Control - WSJ Opinion

America’s air-traffic control system is decades behind those of Australia, Canada, Germany, Italy and the U.K. While these nations build safer, cheaper and more effective digital control towers that can be stationed off-site, the FAA continues to build the traditional towers of years past. While American control-tower staff share flight information with each other via paper flight strips, other countries use electronic flight strips with interactive displays and real-time data. Other providers subscribe to a global space-based surveillance system to track aircraft where there is no radar, such as over the oceans. The FAA doesn’t.

We literally invented aviation.
