 There were nine aircraft in the fleet with a total range of which could carry up to four passengers and two crewmen.Due to the topographic characteristics of the country and the lack of airports at the time, floats were adapted for two of the Junkers aircraft to make water landings in the rivers near different towns.Using these floats, Helmuth von Krohn was able to perform the first inland flight over Colombia on 20 October 1920, following the course of the Magdalena River; the flight took eight hours and required four emergency landings in the water.
