I went to ERAU. My friends went to Purdue. Thankfully I never flew with Riddle, but if I had to compare the 2 flight schools.. I would say that Purdue pilots fly a bit better
(someone at Riddle is going to shoot me for that)
Like AMD87 said... Purdue is a real college. You've gotta have the grades and the dedication to get into it. ERAU's standards are that your parents checkbook is big enough.
I'm not bashing ERAU, I'm just saying that if I had to do it all over again i would've done it differently.
