@G0ULI:
If you check the original thread, you'll find that there are positive and negative aspects to both sides when it comes to connected versus non-connected controls. Remember also that even in a multi-crew airliner, only one of the crew is supposed to be using the controls to fly the aircraft at any one time.
The only reason they used to be physically connected was because prior to hydraulic controls being the norm, there were occasions where extra muscle power may be needed in the event of control failure - with hydraulic controls, that ceases to be an issue. Also note that there have been several similar accidents to this one in aircraft with connected controls.
