I was a T-38 IP in the late 80s and the AF in it's infinite wisdom had screwed up the pilot forecast so nobody was being washed out of T-37s. These guys come to us having lost maybe 3 or 4 guys out of 30. Within a short period of time, we have students in big trouble in all categories, academically, military, and flying. The massive culling begins and we washed out half. It was ugly.
I did have the class leader break down and start crying during the debrief of a formation ride. Not pretty. But it gets worse.
My big kill for that class was the Class Leader. He earned that position due to the earlier departure of the previous class leader. I was the Flight Stan/Eval guy and a firm believer in "cooperate and graduate" and expected them to work together. So what happens? This guy takes a test, I grade it, he busts it, and I hand it back. This bust meant an automatic and potentially fatal ground eval for him. Shortly afterward, he comes to me saying I made an error in my grading. Interesting. I recalled that question quite clearly because it was easy and only one person, our hero, missed it plus I had gone over it twice because I knew the implications of him busting another test. I ask him if he changed the answer, he said no. I ask him to join me talking to the Flt CC and we repeat the process. A short meeting later with the Student Squadron CC and this guy is facing an Article 15 as a bonus to the whole getting thrown out of UPT. He ended up taking the Article 15 and I have no idea what happened to him later.
