I'll fly on a pilotless aircraft when, and only when, the Systems can pass the 'Hudson' test. Sudden loss of all power, huge metro area below: interesting bit of programming!
Ah, but by then our autopilots will have every crash, every incident, every technical anomaly, stored to call upon - in less than a second.
Most of the current drones are remotely piloted rather than "pilotless". It's worth noting that they have a much worse crash rate than any manned type.
While on my walks on Walton's Naze, I came across a display showing a radio controlled rocket being tested during the war. There was it seems, a spinning pit.
The radio valves/tubes were spun up in a centrifuge and those that survived were used in the trials. Not many survived the launch.
N.B. I worked with one of the electronics guys in the 50's and despite telling me numerous tales about that era, he never once mentioned that research. I can only guess he was still under orders to keep quiet about it.
Oh, and he made an electric car which was licensed to be tested on the roads.
