I am an aero structural engineer for NAVAIR. I can't tell you how easy it is to move into industry, I have never tried. There are great opportunities in NAVAIR, there are jobs in which you can learn a great deal and assume significant responsibility early on. There are also terrible jobs, I have seen people put into a job that wasn't really engineering and stagnate there for years (they could have moved and chose not to). There are opportunities to move around the world, but people are often allowed to remain in a job for decades. Most gov jobs allow a good work/family balance, the pay may be a bit lower than elsewhere, but more vacation time than average and paid overtime make it comparable to most places. If you don't like your original job you can look for another, it is not, in my command at least, considered bad form to look for another gov job. I have a challenging very rewarding job, don’t really have any desire to work for anyone else. Bottom line is it's like Mike said the job is what you make of it.
