Map of United States Air Service in World War I

Instructions. Please read! This map of the United States Air Service in World War I allows you to toggle the different groups on and off. The name in the parenthesis corresponds to the name at the top of each group that shows up to the right of the map as different groups are toggled on and off. You can click on the links to learn a bit more about the units. Zoom in two levels around Toul (northeast France) and turn everything on to see how high the concentration of American air units was. More notes below the map.

1st Pursuit Group (1PG) 2nd Pursuit Group (2PG) 17th/148th Aero (RAF)

3rd Pursuit Group (3PG) 4th Pursuit Group (4PG) Lafayette Esc. (FRA)

1st Obs. Group (1OG) 2nd Obs. Group (2OG) German Air Bases (GER2)

Make sure you drill down when using this map. It is only when doing that that you can really properly appreciate the locations of the different bases. For instance, toggle all the check boxes to 'on' and then drill down to Toul so that you can see all of the bases and targets all around there.
