Welcome to your very own WWII B-17G Combat Group formation, consisting in this case of 39 B-17G's (a complete Group would have had approximately 54 aircraft, but this many aircraft would not compile in Gmax). The shape and scale of the formation is as per formation size requirements at the time, although individual missions and tactical evolution dictated changes over time. The B-17's themselves are low poly, but are accurate in shape. The entire formation should have very little impact on framerates, if any. Instructions included.
