A pilot demonstrates how a tablet controls Aurora Flight Sciences' Aircrew Labor In-Cockpit Automantion System (ALIAS), which is mounted in a Cessena Caravan aircraft at Manassas Airport in Manassas, Virginia, October 17, 2016. Government and industry are working together on a robot-like autopilot system that could eliminate the need for a second human pilot in the cockpit.

Is that pilot in the cockpit human or a robot, and does it matter?
