Ribik,
I certainly agree that thinking outside the box (both in the literal sense of trying to avoid the sim mentality and in the sense of exploring new ideas) however these scenarios have a huge number of variables to consider. I once met Capt Al Hayes (the Capt at Sioux City) and listened to him describe the incident and discuss their thought processes. One of the reasons so many did survive is because they had immediate help from the crash rescue and medical personel at the airport. In an off airport landing help could be a long time coming and this could significantly affect the survivability. During the approach they did consider landing on a freeway but discounted it due to the risk to those on the ground.
In any case they did a hell of a job and more than earned their pay that day!
Happy landings
