Completely agree with Pace there. A degree is vital if it is a prerequisite to a specific career choice, such as aero-eng. Otherwise, a degree is a great way to end up with a lot of debt for very little improvement in employment prospects.
Three years industry experience working in your chosen field can, in many cases, be infinitely more valuable than a degree. Certainly when I'm recruiting in to my field I value and experienced candidate significantly higher than one with a degree that may not even be relevant.
