South African phantom monoplanes
In August and September 1914 thousands of South Africans reported night-flying 'monoplanes' they feared were German spies.
1914 CE · -26.20, 28.05 · status: disputed
The account
The scare came in the weeks before the South West Africa campaign of the First World War, when no such aircraft were known in the region.
The sceptical view
Hostile aircraft were ruled out and the plane's origin was never found, leading some to treat it as a case of mass hysteria.
The researched reading
A war-nerves wave: real lights, birds and planets reinterpreted as German spy planes in the first weeks of the First World War.
| Explanation | Weight | Why |
|---|---|---|
| Something known, misidentified | 45% | A contemporary review found that "aeroplanes" over the Cape were large hawks by day and a night light was a train headlamp; bright planets and stars account for many of the night sightings. |
| Perception, memory or mind | 40% | The reports peaked in the first weeks of war, with fear of German spies from South West Africa; this is the pattern of war-scare contagion seen in Britain and Australia the same year. |
| Secret human technology | 5% | German forces in South West Africa had only a handful of aircraft with far too little range to reach the reported areas. |
| A known natural phenomenon | 3% | Meteors and lightning account for a few lights. |
| A hoax or fabrication | 3% | Some pranks are likely, but the wave was mainly sincere. |
| A poorly understood natural phenomenon | 2% | Nothing suggests an unusual natural cause. |
| Genuinely anomalous | 2% | The social context explains the reports without needing anything unknown. |
Official position: Authorities ruled out hostile aircraft and the origin was never found; historians treat it as a wartime scare.
