Aircraft...pilotless RPT heavy aircraft huh? Well let's look at driverless trains. They exist, they are technically feasible but are they widespread? No. Why?
Two reasons. One, the technology is more expensive than having a driver and a driver can deal with failures, obstructions on the line etc better
Two. People like having someone responsible for their safety AT THE FRONT of the vehicle on which they are travelling, because that way that person has a vested interest in getting home safely.
If you did indeed have pilotless aircraft (actually it would be "flown" from a ground terminal) you would still need a PILOT, and a second PILOT in case the first dropped dead. Where is the cost saving there then?
Which just goes to show how poorly thought out your posts are.
