In order for us to fly these planes — unmanned planes that have to fly for months, or perhaps years at a time — we actually have to fly above the weather, above all airspace, Maguire said. Thats between 60,000 and 90,000 feet. Routinely, planes dont fly there, and certainly not drones. Beyond altitude constraints, the planes have to be solar-powered, since theres no fuel that can allow the planes to fly for such long periods of time.
