1928 May: Interwar—Pioneering Air Routes and the Empire Air Mail Scheme
Overview
In May 1928, Australia occupied a formative position in the interwar development of imperial air communications. Long-distance survey flights, route planning, and infrastructure assessments linked Australian aviation to wider British efforts that later matured into the Empire Air Mail Scheme. Although the scheme itself was not inaugurated until 1934, the late-1920s work demonstrated how civil air routes could underpin imperial cohesion, strategic mobility, and future military utility. For the Royal Australian Air Force, these activities reinforced the close interdependence of civil aviation and air power in defence planning.
Glossary of terms
• Empire Air Mail Scheme: A British imperial programme designed to provide subsidised, regular airmail services linking the United Kingdom with Dominions and colonies.
• Survey flight: An exploratory long-range flight conducted to assess navigation, weather, fuel availability, and ground facilities along prospective air routes.
• Imperial Airways: Britain’s state-supported airline responsible for operating and developing long-distance imperial air routes during the interwar years.
• Civil aviation: Non-military flying activity, including commercial transport, mail carriage, and route development.
• Air route infrastructure: The network of airfields, fuel depots, maintenance facilities, and communications required to sustain regular air services.
• Royal Australian Air Force (RAAF): Australia’s independent air service, established in 1921, with both defence and national aviation responsibilities.
• Point Cook: The RAAF’s principal interwar base and training establishment in Victoria, central to early technical and planning work.
• Imperial Conference: Periodic meetings of British and Dominion governments coordinating imperial policy, including defence and communications.
• Strategic mobility: The capacity to move information, personnel, or resources rapidly across great distances for political or military effect.
Key points
• Imperial context of air route development: By 1928, British strategic thinking increasingly treated air communications as an essential element of imperial cohesion. Australia’s participation in survey work reflected recognition that distance was a strategic vulnerability which aviation might partially overcome.
• Role of exploratory survey flights: Long-range flights undertaken in the late 1920s tested the feasibility of linking Australia with Africa, India, and Britain. These flights exposed technical limits in aircraft endurance while confirming that staged routes were practicable with sufficient ground support.
• Civil–military convergence: Although nominally civilian, air route planning was informed by military considerations. Official histories note that any viable imperial airmail network would also offer potential wartime utility for reconnaissance, liaison, and rapid transport.
• RAAF institutional involvement: The RAAF contributed expertise in navigation, meteorology, and airfield assessment. While modest in scale, this involvement strengthened the Air Force’s influence over national aviation policy and reinforced its claim to professional authority in air matters.
• Infrastructure as the critical constraint: Survey findings highlighted deficiencies in Australian and regional infrastructure, particularly fuel supply, maintenance capability, and radio communications. These limitations shaped the cautious pace of subsequent imperial aviation expansion.
• British leadership and Dominion dependence: Planning authority rested overwhelmingly with London, especially the Air Ministry and Imperial Airways. Australia accepted this imbalance, prioritising integration within imperial systems over independent long-range capability.
• Imperial Conference influence: Discussions in the late 1920s reinforced political support for cooperative air development. Air routes were framed as instruments of unity, commerce, and defence rather than purely commercial ventures.
• Precursor to formal EAMS adoption: The technical and organisational lessons of 1928 fed directly into later decisions that produced the fully subsidised Empire Air Mail Scheme in the mid-1930s.
• Implications for Australian defence thinking: Experience gained during this period informed later RAAF views on the importance of bases, staging posts, and communications—concepts central to air power in the Second World War.
• Limits of Australian capacity: Official accounts emphasise that Australia lacked the industrial base and financial resources to shape imperial air policy decisively. Nevertheless, participation ensured access to strategic networks once they matured.
