Scandinavian Airlines (SAS) followed rival Norwegian Air on Friday when it announced that it was now demanding that two crew members be present in the cockpit of its flights at all times. Ryanair already has such a rule in force, as do most airlines in the US.
European aviation authorities also said Friday that it would now be a standard requirement, after a co-pilot left alone in the cockpit of a German Wings flight deliberately crashed the aircraft into a mountainside in France this week. He thus killed not only himself but all the 149 others on board the flight as well.
The tragedy has had immediate consequences. Now, if either the pilot or co-pilot needs to leave the cockpit, another crew member will replace the absent officer.
