1971: Cheyenne Wyoming Abduction
On the evening of August 16, 1971, a military guard named John R. Renz had just been relieved from duty at Francis E. Warren Air Force Base in Cheyenne, Wyoming — a Strategic Air Command installation responsible for Minuteman intercontinental ballistic missiles — and was walking back to his barracks after a beer at the mess hall. He crossed the concrete-reinforced bridge over Cow Creek, an unlit section of the base, and everything went deathly quiet. A paralyzing sound resembling loud heartbeats began. The area around the bridge lit up like daytime. The bridge moved in a wave-like motion, then settled. Renz ran, dropped his pipe, went back for it, and when he stooped to pick it up, he found himself looking at a being roughly three feet away. It was six to seven feet tall, with a head larger than normal, long arms ending in three-fingered claws, three-toed feet with no heels, and a body suit that appeared to be a single piece — head covering and all — with a ribbed silver-gray tracheal tube running from the nasal area directly into its chest. The being raised its right hand and motioned for Renz to come closer. He turned and ran. His next conscious memory was being picked up by soldiers in a military jeep, still on the base. Seven hours had passed. Years later, under hypnotic regression, he recalled being taken aboard a craft, flown to a rocky mountain complex, shown a dead insectoid creature on a floating table, and witnessing a conflict between entity types.

⚠ SOURCE LIMITATION:
This account is sourced from a single website (Aliens-UFOs.com) with no named investigator, no named hypnotherapist, no organizational filing (MUFON, NICAP, APRO), and no contemporaneous documentation. The elaborate regression narrative — involving multiple entity types, an underground mountain base, aerial combat, and inter-species conflict — was recovered years after the event through hypnotic regression by an unidentified practitioner. Readers should weigh the account with these limitations in mind.
Date: August 16, 1971
Sighting Time: Approximately 6:45 PM (1845)
Day/Night: Evening — transitioning to darkness
Location: Francis E. Warren Air Force Base, Cheyenne, Laramie County, Wyoming — concrete bridge over Cow Creek, within the base perimeter
Urban or Rural: Military installation — Strategic Air Command base, Minuteman ICBM facility
No. of Entity(‘s): 1 (conscious memory); multiple (regression narrative)
Entity Type: Tall humanoid (conscious memory); tall humanoid + insectoid beings (regression narrative)
Entity Description: Conscious memory: approximately 6–7 feet tall, medium build through chest and hips, oversized head, long arms, three-fingered clawed hands, three-toed heelless feet. Wearing a one-piece body suit and head covering resembling a wetsuit. Eyes covered by a single-piece lens/blast shield extending across both eyes and incorporating the nasal area. A ribbed silver-gray tube (resembling a tracheal tube) extended approximately 18 inches from the nasal area directly into the chest. Regression narrative: a second entity type — an insectoid creature approximately 4–5 feet long with a wasp-like face, large multi-lens eyes, exoskeletal body, tan-brown with bluish-gray tinge, three-fingered hands, sharp elbow spikes, small shark-like teeth, emitting a foul sulfur/rotten egg odor.
Hynek Classification: CE-IV (Close Encounter of the Fourth Kind) — entity encounter at close range (3 feet), 7 hours of missing time, regression-recovered abduction narrative
Duration: Conscious encounter: minutes. Total missing time: approximately 7 hours.
No. of Object(s): 0 (conscious memory); 1 saucer-shaped craft (regression narrative)
Description of the Object(s): Regression narrative only — saucer-shaped craft with a wide front end and round tapered tail, sitting on two rectangular pillars approximately 50 feet apart. Cockpit with two seats and a control panel bearing unknown symbols. Sound like the harmonics of a powerful electric motor during takeoff.
Shape of Object(s): Disc/saucer — wide front, tapered rounded tail (regression narrative only)
Size of Object(s): Large enough to contain a cockpit with two seats; sitting on pillars 50 feet apart (regression narrative)
Color of Object(s): Not described (regression narrative)
Distance to Object(s): Approximately 3 feet from entity (conscious memory)
Height & Speed: Not applicable for conscious memory; regression narrative describes descent through reddish-brown clouds and flight between mountains
Number of Witnesses: 1 — John R. Renz. Two soldiers in a jeep found him afterward but did not witness the encounter.
Special Features/Characteristics: Environmental anomalies — deathly silence preceding the encounter; the area around the bridge lit up like daytime; a paralyzing sound resembling loud heartbeats; heavy breathing-like sound; the bridge moved in a wave-like motion. Entity biological features — the tracheal tube from nose to chest suggests a life-support system for atmospheric adaptation. The three-fingered clawed hands and three-toed heelless feet are consistent with non-human morphology reported in other cases. Insectoid entity (regression only) — wasp-like face, exoskeletal body, foul sulfur/rotten egg odor.
Case Status: Insufficient Data

Summary/Description: Military guard John R. Renz encountered a 6–7-foot tall humanoid entity with a tracheal tube and three-fingered clawed hands at approximately 3 feet distance on a bridge within Francis E. Warren Air Force Base on August 16, 1971. Environmental anomalies preceded the encounter: deathly silence, the area lit up like daytime, loud heartbeat sounds, and bridge movement. Renz fled, was found by soldiers approximately 7 hours later with no memory of the intervening period. Hypnotic regression years later produced an elaborate narrative involving transport to a mountain complex and interaction with multiple entity types. No investigation beyond the regression session has been documented.

Detailed Report
The Renz case divides cleanly into two narratives with very different evidentiary weights: the conscious memory of the bridge encounter, and the regression-recovered abduction narrative. These must be evaluated separately.
The conscious memory is straightforward and brief. Renz, a military guard at F.E. Warren AFB, was walking from the mess hall to his barracks across the concrete bridge over Cow Creek — an unlit section of the base. The environmental anomalies began first: deathly silence, then a paralyzing sound resembling loud heartbeats, then the area around the bridge lit up like daytime, then heavy breathing sounds, then the bridge itself moved in a wave-like motion before settling. Renz began to run. He dropped his pipe, went back, and found himself face to face — approximately 3 feet — with a tall humanoid entity. The entity’s physical description is specific and internally consistent: 6–7 feet tall, oversized head, long arms, three-fingered claws, three-toed heelless feet, one-piece suit incorporating head covering, single-piece eye lens, and a ribbed tracheal tube from nose to chest. The entity beckoned. Renz ran. His next conscious memory was being found by soldiers in a jeep. Seven hours had passed.
The regression narrative, recovered years later by an unnamed hypnotherapist, is dramatically more elaborate: transport aboard a saucer-shaped craft, flight through reddish-brown clouds to a rocky mountain complex, a small room with a floating table bearing the carcass of an insectoid creature with a wasp-like face and exoskeletal body, observation of the entity’s saucer attacking a beehive-like structure inhabited by approximately 200 insectoid creatures, and the entity shooting dead a cloaked insectoid carrying three small insect-like creatures. This narrative reads as a complete science-fiction scenario and must be evaluated against the general reliability problems of hypnotic regression — including confabulation, leading by the hypnotherapist, and the generation of vivid false memories.
The location — Francis E. Warren AFB, a Strategic Air Command installation responsible for Minuteman ICBMs — adds a layer of significance regardless of the narrative’s reliability. Warren AFB has produced multiple UFO reports across decades, including the 1976 Minuteman III missile-site visit documented separately in this archive.
Researcher’s Notes
The Warren Bridge Entity — Cheyenne 1971 and the Regression Reliability Problem
- Source Chain Assessment: The source chain is critically weak. The account is sourced from a single website (Aliens-UFOs.com) with no named investigator, no named hypnotherapist, no organizational filing, and no contemporaneous documentation. No newspaper account. No military incident report. No MUFON, NICAP, or APRO filing. The identity of “John R. Renz” has not been independently verified against military service records. Without a verifiable source chain, the entire account — including the conscious bridge memory — rests on unverifiable testimony relayed through an anonymous internet publication. The existing Researcher’s Notes on the page contained speculative language about “exopolitics,” “Mantid or Insectoid races,” “overseer roles,” and “localized distortion of space-time” — all of which have been stripped as editorial interpolation inconsistent with this archive’s analytical standards.
- Conscious Memory vs. Regression Narrative: The conscious memory — environmental anomalies, entity encounter on the bridge, flight, discovery by soldiers — is specific, internally consistent, and contains no elements that exceed the boundaries of reported CE-IV cases. The entity description (tracheal tube, three-fingered claws, one-piece suit) is unusual but not unprecedented. The regression narrative, by contrast, describes an elaborate multi-stage scenario involving multiple entity types, an underground mountain base, inter-species warfare, and detailed observation of alien technology. This level of narrative complexity recovered under hypnosis — by an unnamed practitioner, with no session transcripts, no recording, and no corroboration — falls below the evidentiary threshold for archival reliability. The archive presents the regression narrative as reported but cannot assign it analytical weight.
- F.E. Warren AFB Context: Francis E. Warren Air Force Base has been a focus of UFO reports spanning decades. The base housed Minuteman ICBMs and was part of Strategic Air Command. Robert Salas and other former missile crew commanders have publicly testified to UFO activity at ICBM launch facilities during the same era. The 1976 incident at the same installation — documented separately in this archive — involved a fat-cigar-shaped object visiting multiple missile sites over 2.5 hours. The Renz case, if the location is accurate, represents an earlier incident in the same pattern of anomalous activity at nuclear-armed military installations.
- Classification and Status: CE-IV is the appropriate classification for the conscious memory (entity encounter, 7 hours missing time). Insufficient Data is the appropriate case status given the source chain limitations. The case cannot be classified as Unexplained without a verifiable investigator, a named hypnotherapist, or contemporaneous documentation. It is retained in the archive for its F.E. Warren location and its detailed conscious-memory entity description.
A soldier on a bridge, a being with a tube in its chest, seven hours gone, and a regression narrative that reads like a screenplay. The conscious memory is sharp and specific. The regression narrative is unverifiable. The source chain supports neither. The archive holds what it has and notes what it cannot confirm.
