Cressy 'mothership', Tasmania
On 4 October 1960 the Anglican rector of Cressy, Rev. Lionel Browning, and his wife saw a long cigar-shaped object emerge from a rain squall, attended by small discs.

The account
It became one of Tasmania's best-known cases, prompted questions in federal parliament and was investigated by the RAAF. The American atmospheric physicist James E. McDonald interviewed Browning in 1967 and considered the case strong.
The sceptical view
The RAAF's Directorate of Air Force Intelligence concluded the Brownings had seen the rising Moon through moving 'scud' cloud, which gave the impression of flying objects.
The researched reading
A respected couple saw a long shape emerge from a rain squall with small discs around it. Cloud forms and light at sunset after a storm explain much of it, but not all, and the case remains open.
| Explanation | Weight | Why |
|---|---|---|
| Something known, misidentified | 30% | The RAAF concluded the Brownings saw the rising Moon behind moving scud cloud, which gives the impression of objects moving; this is a known cause of "mothership" reports. |
| A known natural phenomenon | 25% | A dark rain squall with trailing virga and cloud fragments can look like a long cigar with small discs coming and going, especially at sunset with low sun lighting. |
| Genuinely anomalous | 23% | McDonald interviewed Browning in 1967 and found the case strong: the cigar stayed still against moving cloud while discs flew out and back, which the Moon-and-scud explanation struggles with. |
| Perception, memory or mind | 8% | Distances and sizes of objects near clouds are notoriously hard to judge; later retelling may have sharpened the "mothership" image. |
| A poorly understood natural phenomenon | 7% | Rare atmospheric optics in clearing storms could produce shapes not easily matched to standard cloud forms. |
| Secret human technology | 4% | The local airfield reported no aircraft, and no secret craft fits the description. |
| A hoax or fabrication | 3% | An Anglican rector and his wife reporting to the RAAF had nothing to gain from invention. |
Official position: The RAAF Directorate of Air Force Intelligence concluded the witnesses saw the rising Moon through moving cloud.
