I'll admit that it has gotten easier to get into Riddle but it isn't as easy as having a pulse and breath!! I think the reason why standards have sorta dropped was to continue to keep enrollment up so the students tuition can pay the bills.
Also, once you get it, you gotta hack it. 2 out of 3 Air Science students won't make it to graduation. So, while you may get it easily, you have to work hard to stay in and succeed. The school is competitive once enrolled... and I guess those rigours and the fact that not everyone is pilot material, weeds out the week (so to speak).
