SOS horror stories abound, and are true no doubt. The DGs in my flight were an F-15 pilot (good dude) and a TPS penguin (engineer type and great dudette). Our flight decided early on to not sweat the small stuff, do our best, and let come what may. We had BBQs, took a trip to a Braves game, and generally just had a good time. It was amazing to see the hard-charging flight of in-their-own-mind SOS DGs implode at the end of the 5 weeks, while our flight of easy-going, get-along types excelled. We didn't win all the competitions, and we got stuck with the "run 3 miles" activity on warrior day (because we were too lazy to figure out how to do something funner...like play flickerball...ha!).
It doesn't have to be doom. You may be saddled with douche bags in your flight, but you'll also have a chance to expand your network outside your MDS.
That said, when I went through it was 3 weeks of work/briefings crammed into 5 weeks of training. I mentally checked out after week 3. I can't imagine how more time in the program will make it better. It will be interesting to get post-mission debriefs from the guys going to the new program.
I'm just lucky I didn't have to fall on my sword and turn down a DG :)
