Having followed this thread for a time, a few comments from a neutral outsider:

First off, I would never post updates on how my training is going in such lurid detail as I'm seeing on this thread. I'd have no problem giving an overview of how the training process works after the fact, but if I were in the Gulfstream/Silver training department, I'd probably crack up reading people giving play-by-play updates on their class. Not to mention, it's easy to figure out who people are on here; I'm sure your training department knows your identities, even if they don't really care as nothing written has been negative/controversial. That's fine. I'm just over-cautious or paranoid, I guess. Also, I noticed that the guys/gals that post constant statuses seem more pressured than those who don't. Which leads into the next part.

Second, someone failed. It's not about 'discouraging' people, as sandrich said. To fly for a 121 carrier, you must meet certain performance standards and levels of aeronautical knowledge. Unfortunately, the individual in question evidently did not. It's sad; I've seen friends fail, and it's hard to watch. The failure is between the individual and the company, and the rest of the class shouldn't take it personally. Just be prepared and be responsible for you. When 25% of your class fails out (as happened at one of my previous employers), you become a bit more reserved.

Again, I wish all of you the best of luck with your training. It's fun to read all about those of you who are excited, motivated, and want to succeed. I just feel that a healthy dose of sparsely applied cynicism can greatly enhance one's job security.
