X-planes: Are they needed in the new era of drones?

America makes special planes called X-planes. These planes are very fast and can do many things. But now, drones are cheap and easy to use. People wonder if America still needs X-planes.

X-planes are important because they help test new ideas. They are different from drones. Drones are small and do not need a pilot. X-planes can fly very high and fast. Some people think they are still useful, even with drones.
