I can imagine unmanned freighters in 20-30 years
Given the rapid developments in reconnaisance UAVs, the western need to minimise military casualities and the potential performance of unmanned combat aircraft, cruise missile technology (OK, so the landing's not up to much
), it may be that on this timescale landings are handled by remote control. Maybe (even) by ATC.
As a freight pilot in 20 years I will be flying aircraft that are being delivered today
I'd have thought that any new contemporary aircraft could easily be converted to autonomous and/or remote control given sufficiently robust computer systems, that I'm sure will evolve in my timescale. 25 years ago the concept of a personal computer looked a little far fetched, we've come a long way.
