Australia, through the Australian Royal Flying Corps in WW1, but mainly through the Royal Australian Air Force in New Guinea in WW2, spear-headed the initial development of, what is today called, Forward Air Control (FAC) for the precise & safe application of close air support. Come see the history of how this happened, while flying a range of different aircraft in MSFS. Hope you enjoy. Cheers.
