Cylinder / Cigar UAP
UAP / Craft type
Cylinder and cigar UAP.
Elongated by appearance.
Long, narrow aerial objects and one of the more distinctive silhouettes found in historical UAP reporting.
Explore the profileWhat if some unidentified aerial phenomena appear less like conventional aircraft and more like long cylinders, tubes, or cigar-shaped objects?
Cylinder and cigar-shaped unidentified aerial phenomena have appeared in witness reports for decades. Descriptions typically emphasize an elongated profile, sometimes with rounded ends and few visible features that would immediately identify the object as a conventional aircraft.
The category is based on apparent shape rather than confirmed construction. Distance, viewing angle, lighting, atmospheric conditions, motion blur, and limited sensor resolution can all affect whether an object appears cylindrical or elongated.

The Elongated Object Profile
Witnesses have described objects that appear tubular, cylindrical, cigar-shaped, or similar to a long oval viewed from the side. Reported surfaces include metallic, gray, dark, reflective, and occasionally luminous appearances.
Some accounts mention rounded ends, smooth surfaces, illuminated sections, or rows of lights. Others describe little more than a featureless elongated silhouette.
Reports may also describe an apparent absence of wings, rotors, tail assemblies, visible engines, or obvious exhaust. These observations vary from case to case and should not be treated as universal characteristics of the category.
02 / History
Historical Reporting
Descriptions of elongated unidentified objects appear throughout modern UFO and UAP literature. Mid-20th-century reports sometimes used terms such as "cigar-shaped," "cylindrical," "torpedo-shaped," or "elongated oval" to describe objects that did not resemble familiar aircraft from the observer's perspective.
Similar terminology continued to appear in later civilian and military reporting. The quality of those observations varies substantially. Some contain detailed witness descriptions, while others offer too little information to determine the object's actual size, distance, shape, or identity.
Because descriptive language changes between witnesses and eras, reports placed in the cylinder or cigar category should not automatically be assumed to represent one consistent type of object.
Historical UFO reports have used terms such as "cigar-shaped" and "cylindrical" to describe elongated unidentified objects. These terms describe reported appearance rather than a verified class of vehicle.

Reported Flight Characteristics
Individual reports involving elongated objects have described a range of apparent behaviors. These can include:
- Slow or steady movement across the sky.
- Hovering or appearing stationary for a period of time.
- Little or no audible sound in some observations.
- Horizontal or vertical movement.
- Changes in apparent speed or direction in individual reports.
- Limited visible aerodynamic structure from the observer's viewpoint.
Reports of rapid acceleration, unusual maneuvering, or silent flight require enough information about distance, viewing angle, wind, camera motion, and sensor geometry before the apparent performance can be evaluated reliably.

Possible Explanations
Possible explanations for elongated UAP observations depend on the individual case. They can include aircraft viewed from an unusual angle, balloons, airships, high-altitude objects, contrails, clouds, atmospheric effects, optical distortions, sensor artifacts, or objects that remain unidentified because the available information is insufficient.
Distance can be especially difficult to judge when an object is seen against an open sky with few reference points. An incorrect distance estimate can produce a correspondingly incorrect estimate of size, speed, and altitude.
More speculative explanations involving advanced propulsion, gravitational effects, electromagnetic systems, or non-human technology have appeared in public discussion. Publicly available evidence has not established that such technologies are responsible for cylinder or cigar-shaped UAP reports.
