Just a matter of time, but I doubt if I'll see it in the remaining 30 years of my career.
Not more than 50 years ago we were still carrying navigators as well as flight engineers, but now we're operating safely with just two pilots, who would have believed that possible 50 years ago? I honestly believe single pilot ops will be the next step if a proven technology is developed, to say take control of an aircraft from the ground, should the only pilot on board become incapacitated. There's obviously plenty of if, buts and maybe's but if a technology is developed at an attractive cost to the airline accountants then you can bet they'll embrace it if it reduces employee costs....
Prehaps a bit sci-fi but then once upon a time so was flying....
