Have you gone ahead and looked at specifically what job you want to be doing in "aerospace engineering". It's like someone saying they want to do chemical engineering or mechanical engineering. Within each there is many many different jobs. Once you know this, how likely is it that you will be able to break in with your degree? Can you break in without the degree? Personally, unless you truly are committed and really want to do this, further education isn't an answer. You will be losing four years of income plus career growth. Based on your description of the work you have been doing, you could likely get a good job outside academia. Maybe what you are really looking for is a change of environment.
