Aviation-related, but not airline
Have you looked into Jeppesen? They have many positions that require (or desire) background in aviation. Since Jeppesen also does rail and marine, and is a corporation that also deals with sales, management, quality, customer service, and so on, you could build great skills that you could then use in the outside world. But, I don’t know if any of you live in the Denver Area, or if are will be willing to move. You can always find several postings on their website.
