Drones Reach Stratospheric Heights in Race to Fly Higher, Longer

This month a drone took off from a missile range in New Mexico and climbed into the stratosphere, joining a race to deliver unmanned aerial vehicles that can fly higher and longer than ever before.

Drones have already shaken up warfare, recently playing a prominent role in the war in Ukraine. But militaries have long sought craft that can provide intelligence at a height beyond the reach of most radar and missile-defense systems, and for extended periods. For commercial users, high-altitude drones can be a way to beam internet services into areas with low connectivity.
