I just looked it up. The CEO of Ford (Alan Mulally) holds a masters degree in aeronautical and astronautical engineering (among others). If you only allow for the term "engineer" to be used to refer to someone who has en engineering educational background, then yes, he is.

Musk, on the other hand, holds a degree in physics. He started a PhD program on applied physics, but quit to pursue his entrepreneurial interests. If you judge engineers purely from an educational perspective, then yes, Musk is not an engineer.

Nonetheless, if we look at wikipedia's description of what "Engineer" means, we get:

> An engineer is a professional practitioner of engineering, concerned with applying scientific knowledge, mathematics, and ingenuity to develop solutions for technical problems.

So, by this definition, Musk is an engineer...
