Whilst I agree in principle with you BlackSheep, I think that it is important that people already working in the industry should have the opportunity to gain a BEng MEng or MSc part time without having to give up work. The OU does science degrees, and I can't see that the issues for science or engineering are all that different.
I have just remembered somebody I know who did a part time Aero-Eng degree at Farnborough college, that might be worth a look.
