Calling what we do a “mission” is ridiculous. A “mission” typically has a critical goal. It’s a dangerous moniker to apply to a commercial flight as it will lead some to attach some inflated importance for its completion thereby raising the possibility of disregarding safety to “complete the mission”.
We don’t fly missions. We take Ma and Pa Kettle to visit the grandkids. While it’s important to get them there safely, comfortably and promptly it’s not critical.
And lastly I don’t remember taking an oath when I got hired.
