Introduction
The familiar image of the Cash–Landrum UFO as a large upright diamond did not emerge from a single photograph or an immediate written description. Instead, it was reconstructed over time from witness interviews, sketches and later retellings. The resulting shape is best understood not as a flat diamond or flying disc, but as an object resembling two truncated pyramids joined together at their widest point, standing vertically. That reconstruction has become iconic, yet the testimony behind it contains important nuances. The witnesses consistently described a brilliant, vertically oriented object, but the exact geometry became more defined in later interviews than it appears in the earliest documented accounts.[Wikipedia]WikipediaCash–Landrum incidentCash–Landrum incident
How the upright diamond reconstruction emerged
The best-known reconstruction comes primarily from the August 1981 interview conducted at Bergstrom Air Force Base. During that session, investigators asked Betty Cash to sketch the object “if it had a discernible shape.” She produced a simple outline, apologising for her drawing ability while identifying it as “a diamond shape.” Vickie Landrum then examined the sketch, agreed that it represented the object, and added that flames extended downward from its lower end. The signed drawing became the reference image reproduced in many later books and documentaries.[Cufon]cufon.orgBergstrom AFB Interview of Betty Cash, Vickie & Colby Landrum, Part 1 of 2August 17, 1981…
Although commonly described as diamond-shaped, the sketch itself is more specific than that label suggests. It does not depict a flat geometric diamond. Instead, both the top and bottom terminate in flattened ends, creating a profile much closer to:
- two truncated pyramids joined base-to-base;
- an elongated spindle with flat upper and lower faces; or
- a vertically oriented double-frustum.
This distinction explains why some investigators have alternatively described the object as spindle-shaped, top-shaped or cone-like while still referring to the same witness testimony. Richard Hall, writing for NICAP, explicitly noted that the object could be described as “cone-, spindle-, or top-shaped” depending on which geometric feature was emphasised.[Nicap]nicap.orgUFO ReportUFO ReportDecember 29, 1980…
Why the object is often drawn as two joined pyramids
The widespread reconstruction reflects several recurring elements from the testimony rather than a single explicit technical description.
First, the object was consistently portrayed as standing upright rather than flying horizontally. The witnesses described flames emerging from the lower end while the craft hovered above the road, making a vertical orientation central to every later illustration.[Wikipedia]WikipediaCash–Landrum incidentCash–Landrum incident
Second, both ends were remembered as flattened rather than sharply pointed. Jerome Clark’s synthesis of the testimony described the object as resembling an upright diamond “with its top and bottom cut off,” matching the signed Bergstrom sketch. This creates the appearance of two truncated pyramids meeting at their broadest sections rather than a perfect rhombus.[Wikipedia]WikipediaCash–Landrum incidentCash–Landrum incident
Third, the object appeared widest around its middle. Witnesses also mentioned a ring of small blue lights encircling this central region, reinforcing the impression that the maximum diameter occurred halfway up the structure rather than near either end.[Wikipedia]WikipediaCash–Landrum incidentCash–Landrum incident
Taken together, these features explain why later artists typically reconstruct the craft as a symmetrical three-dimensional solid rather than a flat diamond outline.
How witness sketches shaped the familiar image
Most modern depictions ultimately trace back to one relatively simple drawing.
The original sketch established several features that became standard in subsequent illustrations:
- a vertically oriented central body;
- flattened upper and lower ends;
- overall bilateral symmetry;
- flames projecting only from the lower portion.
Later illustrators frequently expanded upon this sparse drawing by adding metallic panels, windows, seams, rivets or complex surface textures. Those additions should be treated cautiously because they are artistic interpretation rather than direct witness description.
This distinction matters because the witnesses repeatedly stressed the extraordinary brightness of the object. They described an intensely luminous craft whose glare made close inspection difficult. Under those viewing conditions, observers may perceive an overall silhouette while losing the finer surface detail needed to identify structural features. Consequently, the testimony supports greater confidence in the object’s outline than in its external construction.[wikipedia.org]WikipediaCash–Landrum incidentCash–Landrum incident
Why the geometric reconstruction remains uncertain
The most significant uncertainty concerns when the adults themselves became confident about the diamond shape.
The earliest documented reports, recorded roughly one month after the incident, indicate greater hesitation. Betty Cash reportedly stated that she could not determine the shape because the lights were too bright, while Vickie Landrum likewise said she could not tell. In those early accounts, seven-year-old Colby Landrum was described as the person who most confidently insisted the object resembled a large diamond.[Wikipedia]WikipediaCash–Landrum incidentCash–Landrum incident
By the August 1981 Air Force interview, however, both adults endorsed the diamond-shaped sketch without apparent reservation. That evolution does not necessarily imply fabrication. Memory research has long shown that witnesses often refine descriptions while repeatedly recounting unusual experiences, particularly when converting an overwhelming visual impression into a simple geometric form.
Nevertheless, historians generally distinguish between:
- the immediate visual experience reported shortly after the event; and
- the later stabilised reconstruction represented by the signed sketch.
Recognising that distinction prevents overstating the independence or precision of the original observations.[Wikipedia]WikipediaCash–Landrum incidentCash–Landrum incident
What can be stated with confidence
Across the surviving testimony, several geometric characteristics remain comparatively well supported:
- the object was perceived as vertically oriented rather than horizontal;
- it was widest near its centre;
- both the upper and lower ends appeared flattened;
- flames emerged from the lower end during repeated bursts;
- the outline was remembered more clearly than any detailed surface features.
Other commonly illustrated characteristics are much less secure, including the exact proportions, precise cross-section, surface texture, thickness, windows or mechanical details. Those elements originate largely from later artistic reconstructions rather than directly observable features described by the witnesses.[nicap.org]nicap.orgUFO ReportUFO ReportDecember 29, 1980…
The most accurate modern reconstruction
If the witness testimony is reconstructed as conservatively as possible, the famous Cash–Landrum object is best visualised as a bright, upright solid resembling two truncated pyramids joined at their widest point, with flat upper and lower faces, a broad central section marked by blue lights, and intermittent flames projecting from beneath. That reconstruction reflects the convergence of later interviews and the Bergstrom sketch while acknowledging that the earliest recorded testimony was less certain about the precise outline because of the object’s intense brightness.[cufon.org]cufon.orgBergstrom AFB Interview of Betty Cash, Vickie & Colby Landrum, Part 1 of 2August 17, 1981…
