I'm not saying it didn't exist before Kegworth what I am saying is that Kegworth was a prime example of what can happen when communication breaks down between the two groups.
I have been flying for 22 years and pre Kegworth CRM was hardly discussed or talked about. Post Kegworth and its all about joint excercises at SEP etc.
I have lost count of the amount of times Kegworth is talked about when the whole conversation comes up about CRM.
Kegworth I feel, was the incident that emphasised the need for good CRM on both sides.
