Crew/Cockpit Resource Management
I would suggest you get comfortable with this concept and practice, Ian. Then, if you want to do a real service to humanity, investigate and report why CRM isn't being put to extensive use in hospitals everywhere. CRM is the pride of much of our industry, and it transfers readily to other disciplines.
Reportedly, some 80,000 people die from mistakes in US hospitals every year. Visualize that number of fatalities in airline accidents.
The order of command in the cockpit in some cultures is:
the Captain,
then God,
then whoever else.
It's said to be even more so in operating rooms.
