Firstly degrees calling themselves Aerospace Engineering and Aeronautical Engineering are pretty much the same.
Mechanical engineering will concentrate far more on stress analysis, detail design, etc. and less on the whole-vehicle design stuff which comes in the Aero-Eng courses. Nonetheless if you are looking at a job with, say BAE, it'll stand you in very good stead and I can't say I've ever met a long-term unemployed MechEng graduate.
Skip electrical and power engineering the aerospace coverage will be limited. Electronic Engineering less so, but there are specialist "Aerospace Systems" degrees which are essentially electronics with lots of Avionics design and most of the core element of Aero-Eng - Southampton's for example.
Good universities: Southampton, Glasgow, Bath, Imperial (if you like Maths), Hatfield, Kingston all in my opinion produce good graduates (I'm sure I've missed somebody out, there may well be equally good departments out there I don't know).
Could I also mention a thread I started this morning on "Questions" at
http://www.pprune.org/forums/showthr...threadid=97350 which has some mild relevance.
