Whatever you like to call it either being scarred, concerned or anxious it all means the same thing.
Do we press on into questionable weather or turn back. Do we let a group of drunk people board our plane! You may say I would never do that but people make strange decisions when under the pump.
If any experienced pilot looks back at their career I am sure they can recall a time when they were flying that they wished they did something differently. The experiences enable you to make better decisions in the future.
Will young cadets really have these experiences in a simulator?
