There are some part time degrees which you may want to consider for degree in aero. But embrie riddle university in USA runs a degree program distance learning.but how far this degree will get you is open to debate. I m a b1 maintenance engineer.if it's maintenance you are looking for then I can help drop a pm.if you looking at design or manufacture side then u need a solid degree from proper university. the only way u keep your job and study as well is part time not distance learning and get decent degree from a decent university
