I did a degree in Aerospace, before I did the Pilot training, and finished it in 2003 (when the good times were on) and like about 80% of the other aerospace graduates found it extremely difficult to get a job.
Every time you applied for an aerospace job you were asked the same question "How much experience have you got"? the answer of course was "None because I've been at University getting this aerospace degree" and that was all she wrote... no job.
It's always been difficult to get an aerospace job in this country and getting one now is damn near impossible as there's hundreds of people applying for each job.
If you want to do the degree just because you enjoy learning about aviation and would enjoy doing the degree then go for it. If you would be doing it so that you hope it will help you get an aerospace job then honestly dont bother.
3 years of actual work experience is worth 20 degrees.
