A recently discovered map in the Public Records Office in Kew showing all the proposed Imperial Air Routes has uncovered some interesting unknown finds.
The map is dated “Air Routes 1931” but it is suspected that this is a future proposal of sites, probably issued around August September 1930, prior to the loss of the R101 and when many decisions had been made regarding the next phase of the Imperial Airship Programme.
Proposed Mast
One of the locations which was shown was the proposal of a mast in Bombay. The mast is in a strategic location on the route down to Australia.
Nothing more is known of the proposed Bombay mast; however, it is quite unlikely that this would be built with the proximity of other proposed masts in the area.
However, the mast could also service those airships travelling down from India, to Perth in Australia, as it sits on a geographic line directly southeast connecting those locations.
