Miami Springs was founded by an Glen Curtissaviation pioneer, and thus, the fate of the city has always been intertwined with the aviationaviation industry, particularly since Miami International Airport (MIA) is located just south of the city on the southern border of NW 36th Street. The airline industry brought many residents from airline crew bases, as well as employment opportunities at the airport, which brought much prosperity to the city. This dependence, however, left the city vulnerable. The sudden 1991 collapses of both Eastern Airlines and Pan American World Airways left many Miami Springs residents unemployed and unable to afford living in the neighborhood. Given that the businesses in Miami Springs had always relied upon the large disposable incomes of the employees of the large airline carriers, the bankruptcy of both corporations in the same year created a chain reaction, eventually causing many small businesses to close their doors. Despite the closure of the airlines, from a residential standpoint, Miami Springs remained strong. The city is often seen as blessedly isolated from the perceived turbulence of the rest of Miami-Dade County. This has continued to provide ample replacements for the older residents who are lost over time. Nonetheless the legacy of the airline closures remains. Residential mileage taxation rates hover near the state mandated maximum because continued weakness in the commercial sector makes it an insufficient source of tax revenue.
