No Fly Zone, what you say is correct. However in the real world you do not know how behind locked doors the company react to go arounds or failure to "get in" even in responsible airlines they apply pressures. For instance if you divert to alternate I know some airlines will ask why you did not hang about & then declare a mayday when down to final reserv. Am not saying in this case anything like this happened but we do not know what pressures the crew were under in reality or what pressure they perceived.
