March 1975: The Football-Shaped Riser at Lake Sorell, Tasmania
On March 14, 1975, three weeks after a much more dramatic sighting at the same lake, a Mr. Knapek, his two sons, and two family friends, camped near Lake Sorell, Tasmania, watched a bright yellow, football-shaped object rise slowly from behind a stand of trees, then shoot rapidly upward into the southwestern sky, shrinking to star size and vanishing in just five seconds.
Date: March 14, 1975
Sighting Time: Undocumented — early evening, around a mealtime snack break
Day/Night: Undocumented, likely dusk given the object’s visible color change as it receded and the described mealtime context
Location: A clearing approximately 1 mile east of Lake Sorell, Tasmania, Australia
Urban or Rural: Rural
No. of Entity(‘s): Undocumented
Entity Type: Not Applicable — no entity described
Entity Description: Not Applicable
Hynek Classification: DD (Daylight Disc) — metallic or whitish object seen in the day, if occurring before full dark, or NL (Nocturnal Light) if at dusk/night; the exact lighting conditions are not specified in the source. The object was directly resolved as a solid, football-like shape rather than an ambiguous point of light, favoring DD if daylight conditions applied.
Duration: Approximately 5 seconds total, from first notice above the treeline to disappearance
No. of Object(s): 1
Description of the Object(s): A football-shaped object that rose slowly from behind trees about 300 yards to the west of the group, then, once clear of the treeline, accelerated rapidly upward into the southwestern sky, shrinking to star size before disappearing from view at an estimated 75 degrees of elevation. As it receded, its color shifted from bright yellow underneath (with a lighter yellow on top) to a whiter, brighter tone.
Shape of Object(s): Football-shaped
Size of Object(s): Estimated by witnesses at approximately 50 feet across
Color of Object(s): Bright yellow underneath, lighter yellow on top; shifted to a whiter, brighter tone as it moved away and gained altitude
Distance to Object(s): Approximately 300 yards at first notice, behind trees to the west of the group
Height & Speed: Rose slowly at first, then accelerated rapidly once clear of the treeline, climbing to an estimated 75 degrees of elevation before vanishing — the entire ascent taking only about 5 seconds
Number of Witnesses: 5 — Mr. Knapek, his two sons (ages 13 and 15), and two family friends. The two boys were the first to notice and point out the object.
Special Features/Characteristics: No check for physical landing or ground traces was made at the site, per the original source. This sighting occurred at the same lake, though a different location and with an entirely different witness group, roughly three weeks after a separate, more extensively investigated sighting archived elsewhere on this site.
Case Status: Insufficient Data — a brief, five-witness family account with no photograph, no ground-trace investigation, and no independent corroboration beyond the group’s own testimony

Summary/Description: A Mr. Knapek and his two sons and two friends sighted an object while camped in a clearing about 1 mile east of Lake Sorell, Tasmania. They were about to have a snack when the children, ages 13 and 15, pointed out an object rising slowly at first from behind trees 300 yards to the west, toward the lake. The object, once above the trees, rose rapidly and shot up into the southwestern sky, diminishing to star size and then being lost to view at 75 degrees elevation. The whole event took only 5 seconds. The object was football-shaped and estimated by the witnesses to be about 50 feet across. It was bright yellow underneath with a lighter yellow on top, and as it moved away the color became more white and much brighter. No check was made for landing traces.
Related Cases: 1975: The Lake Sorell Searchlight, Tasmania — a separate, more extensively documented sighting at the same lake roughly three weeks earlier, involving different witnesses and a differently described object; the two were originally reported together in the same APRO Bulletin article but describe distinct events
Detailed Report
This brief sighting occurred at the same lake as, but is otherwise unconnected to, a much more elaborate and closely investigated encounter reported three weeks earlier. Mr. Knapek was camped in a clearing about a mile east of Lake Sorell with his two sons, aged 13 and 15, and two family friends, when the boys spotted an object rising slowly from behind a stand of trees roughly 300 yards to the west. Once clear of the treeline, the object accelerated rapidly, climbing into the southwestern sky, shrinking to the apparent size of a star, and disappearing from view at an estimated 75 degrees of elevation — the entire event lasting only about five seconds. The group described the object as football-shaped, roughly 50 feet across, bright yellow on its underside with a lighter yellow top, its color shifting toward white and increasing in brightness as it climbed away. No search for physical ground traces at the site is mentioned in the source material. This account is considerably shorter and less detailed than the February encounter at the same lake, offering no description of sound, radio interference, or other secondary effects.
RESEARCHER’S NOTES
The Football-Shaped Riser — Lake Sorell, March 1975
- Classification Assessment: The exact lighting conditions (daylight versus dusk) are not specified in the source, leaving some ambiguity between DD and NL; the object’s directly resolved, structured shape (football-like, with a distinct underside/topside color difference) argues for DD if the sighting occurred in daylight.
- Source Chain Assessment: Documented by the same APRO investigator, William K. Roberts, as the separate February 1975 Lake Sorell case, published in the same bulletin issue. Unlike that case, the witnesses here are named rather than pseudonymous, though only the family surname (Knapek) is given, with no further identifying detail or independent follow-up cited.
- Evidentiary Weight: No photograph accompanies this account, and no ground-trace investigation was conducted despite the object’s reported low-altitude rise from behind nearby trees, a missed opportunity for physical evidence given how close and low the initial sighting was.
- Pattern and Comparative Context: A rapid, near-vertical departure that shrinks the object to star size within seconds is a common feature across many UFO reports and, on its own, is not distinctive enough to rule in or out a specific cause. The proximity in time and place to the separate, more elaborate February sighting at the same lake invites comparison, but the two accounts differ enough in object description and behavior that they should be treated as independent reports rather than two observations of the same phenomenon.
- Geographic and Historical Context: This sighting adds to a short cluster of reported activity at Lake Sorell in early-to-mid 1975, alongside the separate February encounter, suggesting either a genuine period of local activity or simply heightened local attention to the sky following the earlier, well-publicized sighting.
A brief, five-witness family sighting, over in five seconds, with no photograph and no ground-trace check despite the object’s low, close initial position. Distinct from the more elaborate Lake Sorell sighting three weeks earlier, though from the same general area. The case stands as Insufficient Data.
“The whole event took only 5 seconds.”
