I'm not sure because I wasn't there. From the information that is available so far, you really would need to be there to come to any conclusion of whether their actions were the right ones or not. What I would assume is that they were professional pilots acting in a professional manner to ensure the safe operation of the flight. If you have the specific details of the information that the pilots had in front of them and would care to share that with us, then we may be able to answer your question....
