Most other jobs and professions build value over time and offer some kind of crossover to other professions if the need arises. As a pilot dumped on the street tomorrow they have Zero value to the outside job market. They have to start totally over.
The determination and dedication that is takes to stick with aviation as a career I would think would be a good trait. On top of that I would think that the Situational Awarness, Assertiveness, Decision Making, Communication, Leadership, Adapatability/Flexability, and Mission Analysis would all be highly desired on the civilian market. I knew that CRM would come into use someday!
