No, not at all difficult. Sully and the crew did an excellent job and and I also said it at the end of my posting. The result of his and the crews work was the best so they did a perfect job but there are many factors involved in a situation and it takes only to change one of them for everything going totally wrong. I was proud and emotional about another fellow pilot being able to save all those lives and do such a great job together with his crew. I just have not seen anything mentioned about the A320 systems or about how lucky we all are that everything was there to let the Crew do such an excellent job.
