On of the locations which was shown was the proposal of a mast in Colombo, then part of what was known as Ceylon, now Sri Lanka. The mast is in a strategic location on the route down to Australia. Nothing more is known of the proposed Colombo mast, however it is quite likely with the expansion of the route to Australia that the mast could service those airships travelling down from India, to Perth in Australia, as it sits on a geographic line directly south east connecting those locations.

Ceylon, at the time, was also an important communications / trading partner of the British Empire.
