Not just business:<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Korean_Air_Cargo_Flight_8509" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Korean_Air_Cargo_Flight_8509</a><p>In most cultures co-pilots are encouraged to speak out when the pilot has or is about to make a mistake. There were several Korean Air crashes where the co-pilots knew the pilot was wrong and did nothing, in some cases costing them their lives. After recognizing this there was a strong push to change the culture at Korean Air, but I don&#x27;t know that this was a lesson brought over to other industries.
