The X-15 Rocket Plane primarily flew in the mesosphere and the lower part of the thermosphere, reaching altitudes of about 50 miles (80 kilometers) and beyond. This region is above the troposphere and stratosphere, where the atmosphere becomes increasingly thin. The X-15's flights were significant for gathering data on high-altitude flight and space travel.
