no more room for pilots on modern airplanes.
What rubbish.
At any given moment there are over 5,000 aircraft in the air, 24 hours a day and 7 days a week.
Because of the complexity most of these will be controlled by computers which can take decisions quicker than any human and store masses of information.
Once in a while, maybe once every month or so, i.e. once every million flights, the aircraft presents problems that are outside of the ability of the computer.
In these situations that aircraft will crash unless a 'human' takes over.
In 90% of the cases the pilot, due to training and experience, will rectify the situation and resolve the problem, often with little loss of life or aircraft.
Occasionally the pilot is not up to the situation either because the situation is beyond him/her or due to lack of personal ability. This results in tragedy.
The human pilot is always the last chance when everything else goes wrong. The answer lies in better pilot training and company procedures not removing the human totally.
