I've done a lot of research on this as I stated earlier in this thread and others. It became quite clear the UND, WMU, and Purdue are a cut above in terms of aviation programs while other schools like OSU (just got a $10 million dollar grant to improve the facilities), LA Tech, and MSU to name a few are not at all far behind. There are so many good aviation programs and my advice would be to VISIT the ones you are most interested in. I almost didn't go to UND but now, because of my visit and talking to graduates, and current students, it's my top choice. On the other hand I was able to rule out Purdue after my visit.
