Yes, sleep is in fact a prerequisite to planes flying. We have very strict laws about it actually. Most planes are only able to fly because a human (who does sleep) is piloting it.

The drones and other vehicles that can fly without pilots were still programmed by a person (who also needed sleep) FWIW.
