How do you become a aeronautical engineer?

Either, do BTEC NATIONAL DIPLOMA IN MECHANICAL ENGINEERING (2 YEAR COURSE level 2/3) or AN AERONAUTICAL ENGINEERING COURSE IN CERTAIN COLLEGES, LIKE SUSSEX, or you could do an APPRENTICESHIP IN AERONAUTICAL/AEROSPACE ENGINEERING and earn while you train. :). The Grades you need will be A*-C in Maths, English and Science (Physics) :)
