For any of you thinking of doing one of the formation clinics I put together this video it has some great narrative in it. I was able to get out to the clinic a day early which I highly recommend and sit right seat of Larry "Joker" Brennan's plane. He did a great job of talking about the maneuvers as he was flying them. I didn't think much of it until I was in the left seat the next day, I was barley able to say a word I was concentrating so hard.
If you read this guide which I put the link below and watch the video you will have go idea of what goes on with the formation clinic. Newbies fly 2 ship formation and the advance do the 3 and 4.
