Midway observations

[Volcano Man]

No problem. The minimum point defines the start point in the arc and the maximum point describes the ending point in the arc. So, if a minimum point is 0 degrees and the maximum point is 90, then the planes will go out on a 90 degree angle to the northeast (maybe it is better to think of the minimum as the "start" point and the maximum as the "end" point in the arc).

If you specify the above example backwards, with the minimum point being 90 degrees and the maximum being 0, then you are essentially saying that the arc will be 270 degrees, so that the planes will all go out starting at the 90 degrees and ending at 0 degrees (so that they go out to the east, southeast, south, southwest, west, northwest and north).
