Check Your 6!, the guys running the game usually hand out clipboards to the guys running the planes, who clip their planes' roster on it and plot their actions each turn. Most of us will usually clip the quick reference sheet underneath for easy access. Well, the other day I received a clipboard with a clear plastic back. It wasn't intended, but I realized I could put the most useful side of the QRS facing backwards and just flip my clipboard over to take a look at it! Simple, and useful.
