Desirable Languages

What languages do I need to learn well in order to be desirable to employers?
I should note that I'm majoring in Aerospace Engineering.

I guess that was supposed to be sarcastic.

Aerospace engineering isn't as bad as people make it out to be.
It's the 5th or 6th ranked in engineering in terms of job numbers irrc. Plus it's so close to mechanical engineering you can often get a job with many other companies not related to aero at all.
