Thanks for the information and kind words. His Lt didn't give him any insights on other paths aside from OCS however we have a close family friend who did PLC, Flew A4s and Hornets and then 767 for AA for many years that has been trying to steer him to PLC since last summer, so that will be his next path to fully explore.Sorry to hear this. Capt MJ, as usual, has great advice.
I just wanted to point out the NROTC sideload process for your edification. It's a national competition that is not handled by the unit, so the advisor would have no real insight into how competitive he was, since he didn't know the competition. DS only received a sideload after first semester of his 3C year. Also not everyone who commissions via NROTC receives a scholarship.
No doubt your son's determination will help him work through this particular set back. Did he get any info on his ability to commission through another program?
