Your original comment is absolutely true, except when a good mutual friend and I went to Dallas in February for a "cleared" job fair, it was nothing but aerospace companies looking for computer wonks and engineers. They were not looking for linguists or analysts. At all. They looked at me funny when I told them I didn't have a degree in aerospace engineering.
Just a word to the warning, those clearance jobs are out there (I have one), but they're not everywhere!
