Mil route! ROTC. If ur fam is tight on cash apply for financial aid. Try for some scholarships....even the $500 ones can help out.
I don't recommend enlisting first, if u want to be a pilot...it's going to eat up years that you could be getting your degree and then commissioned. It's about a yr wait to go to UPT, then about a year at UPT, then a 10 yr commitment. You will b eligible to separate around the 12 yr active duty mark (~17 yrs from now).
...I also took out student loans!! Be smart on this one...it would suck to have huge debt after college.
