The history of College Park has been closely linked with what is now known as Hartsfield–Jackson Atlanta International Airport — airport development having spurred several radical changes to the landscape of the municipality over the course of the 20th century. In 1966, a study funded by the Department of Housing and Urban Development suggested that the introduction and expansion of jet aircraft travel would place the airport and surrounding communities, including College Park, into conflict; ultimately, the study concluded that "the only effective way to control the use of land is to own it," suggesting that the airport would have to acquire the properties it would be in conflict with in order to expand.
