unpiloted
No one aboard
Unpiloted describes a vehicle or craft operating without a human pilot aboard.
The term applies especially to aircraft, spacecraft, and watercraft controlled remotely or autonomously: an unpiloted drone, unpiloted missions to Mars.
Unlike unmanned, it focuses specifically on the absence of a pilot rather than crew generally.
