Is it possible to be an engineer without an engineering degree?

I think you have to break it down to the industry that you are speaking of distinctively. In a civil industry for example you would have your PEs since they have to be certified to stamp designs and such. In the type of industry I work in, Military R&D I don't know a single engineer with their PE. A lot of these engineers have their doctorates and have been working for 20+ years but does it not make them engineers if they haven't taken a PE certification exam? Also if in industry two people are performing the exact same job functions shouldn't they have the same job title no matter what their degree is? Job titles describe what you do in your current position, not what degree you received.
