The mind boggles
Putting a higher risk (ie relatively untested) autonomous system into a high risk environment. What could possibly go wrong ?
I wonder if the software is designed to consider things not on the same plane (horizontal plane, not thing with wings). Yes, planes have autopilots, but I bet they go through a heck of a lot more testing and far more rigorous testing than a constantly in development autonomous car
How would they interact with the guys on the ground with their semaphores and with the fire service in emergency cases ??
Perhaps its time to maintain a list of airports to avoid.
