I donīt get the hero point of this crew, you have a complete hidraulic failure 1 hour after T/O and you fly all the atlantic to Warsaw? Either someone got the wrong information or these guys are suicidal!!!
They did not have a complete hydraulic failure. They lost one of THREE "separate and independent" hydraulic systems. Not a very big deal and certainly not suicidal. In the very unlikely event that another hyd system were to fail on the same flight a landing could have been made on the one remaining system. And consider this: it doesn't make any difference at all whether you try your luck at alternate gear extention (which is supposed to work anyway) in New York, or eight hours later in Warsaw.
In my opinion, a perfectly logical decision. You just can't beat Murphy if he decides to fail the alternate system as well. Looks to me the crew played the hand they were dealt perfectly.
