I didn't say Sully used his eye balls to decide where to land but how to ditch. What I said was the eye ball in visual conditions is the only way to touch down in the proper attitude and speed. He did it well and we all hope we could have done the same. The altimiter is unnecesary once you have chosen your touch down ditching spot.
Hopefully we all could have done the same thing. We aren't really trained for it but we all should have the skill to do it.
The new autopilot monitor guys with low time won't be able to do it unfortunately. The old guys can.
