I am creating a map showing flight paths originating in the United States and traveling to Asia and Europe. I need a projection for the world that will focus the United States in the center of the map, with Asia showing up to the west and Europe to the east. Does anyone know where I might find a projection like this?
Edit: I am working in ArcInfo 10.

I don't know of a predefined one but you should be able to take any good global projection (for some value of good) and change the central meridian to be one running through the US instead of through Greenwich.
You will need to post more details of the system you are using before we can give detailed instructions on how to create a custom projection.
