The old airport of Palmas, Brazil, is missing.
It was an airport which operated temporarily from shortly after the inauguration of the city - somewhere in 1991 - through the inauguration of the current Lysias Rodrigues Airport, in 2001.
I couldn't find detailed information about that aiport. I gathered some data with the help of Wikipedia and historical satellite images in Google Earth. According to these sources, the airport had the IATA designation as PMW and ICAO designation as SWPJ, operated "temporarily" in over 10 years and its runway was 1800 x 30 m, which was sufficient for large aircraft to operate.
Below there are 2 satellite images taken from Google Earth, showing the location of the airport with respect to the current one and the demonstration of the runway's dimensions. The airport coordinates were taken by myself with Google Earth and is of the point at the center of the runway:
