NASA Advances High-Altitude Traffic Management

High-altitude flight is getting increasing attention from sectors ranging from telecommunications to emergency response. To make that airspace more accessible, NASA is developing an air traffic management system covering those altitudes and supplementing its work with real-time data from a research balloon in Earth’s stratosphere.  Aircraft at high altitudes – 50,000 feet or higher, or roughly 10,000 to 20,000 feet above most commercial
