To return to the "luck vs. skill" issue raised several posts ago, surely it was a case of both and not either/or?
In different circumstances (that is to say, where neither the Hudson nor anything else which could have performed the role of a "runway" was available) no amount of skill would have prevented a very different outcome (i.e. fatalities).
The pilot flying the A320 exhibited great skill, but he (and all those onboard) were also very lucky. Put another way, their luck enabled the pilot to exhibit his skill.
The same is true, for example, in the Air Transat case cited above. What would have happened if no airport had been within "gliding" distance?
(Wasn't there another Canadian airliner - Air Canada, I think - which also "glided"? A mix-up between imperial and metric fuel quantities, if I remember correctly.)
