Members of the Louisiana Air National Guard's 159th Fighter Wing fly in a joint dissimilar aircraft formation with pilots from Chile, Argentina, Brazil and France as part of a training mission in Chile, Oct. 17. Pilots from the five countries have been working together in an exercise called "SALITRE II," which is a Combined Air Operations Center training opportunity that allows the different countries to train together on things like air search-and-rescue and aerial refueling.
