pilotless airliners are safer...40 years of flying here...they are safer only for pilots and the passengers who elect not to fly on them and stay on the ground.
San Francisco created a world class subway system called BART (bay area rapid transit). IT was to be automated with NO drivers. But it didn't work and they had to put human drivers in the trains.
Someone will develop a crewless airliner. But will find out the hardway that it won't work just right.
Oh well. Remember that on the first lunar landing, the automatics were taking the L(E) M to a landing on a crater, Neil took over and landed on a safe spot.
