"The Hudson ditching was due to bird strikes taking out both engines.You might be thinking of the Colombian crash, if you are thinking at all."
I'm definitely thinking; and what I'm thinking is that, yes, humans can use their skill and initiative to get out of a potentially disastrous situation, as Captain Sullenberger did, but human motivations and emotions can interfere with the decision making process and end up creating the disasters.
Captain Francesco Schettino admitted that he was trying to "impress passengers" when he steered the Costa Concordia too close to Giglio, sinking the ship and killing 32 people.
I'm sure that Miguel Quiroga, pilot of the aircraft and partner in the airline, had his own reasons for flying without an adequate fuel reserve but in the end his poor judgement, not a mechanical failure, has killed 71 people.
With humans there are inconsistencies, with heroes like Chesley Sullenberger at one end of the scale and villains like Francesco Schettino and Miguel Quiroga at the other; replacing men with machines is only going to happen for valid safety reasons, when it's absolutely clear that, statistically, machines can operate more safely than people. I say "statistically" because there will always be edge cases where a machine won't perform as well as the best humans can, but statistically, when things go wrong, you'll be extremely lucky if there's a Chesley Sullenberger at the controls.
