1977: Security guard sees oval UFO with bright headlights

THINK ABOUTIT UFO SIGHTING REPORT

In October 1977, an 18-year-old security guard at the French and Hecht plant in Walcott, Iowa, witnessed a silent, oval-shaped craft featuring two brilliant, flashing “headlights.” This Nocturnal Light (NL) encounter was characterized by significant Electromagnetic Interference (EM), as both the witness’s radio and walkie-talkie malfunctioned during the event. Local environmental effects included the sudden silencing of nearby livestock and insects, as well as a reported television failure in a neighboring farmhouse. Despite local skepticism and ridicule from law enforcement, the case was documented by the Center for UFO Studies (CUFOS).

Date: October 1977

Sighting Time:   Approximately 1:00 a.m..

Day/Night: Night

Location: Walcott, Iowa

Urban or Rural: Rural

Hynek Classification: NL (Nocturnal Light) Point or extended luminous source observed at night.

Duration:  The witness watched the object for several minutes before it departed while she looked for other witnesses.

No. of Object(s): 1

Size of Object(s):  Described as being roughly the size of a compact car or slightly larger, appearing “oval” in shape.

Distance to Object(s):  The object was estimated to be within 100 yards of the watchtower when the mercury vapor lamp went dark.

Shape of Object(s): Oval

Color of Object(s): a pair of bright “headlights” flashing

Number of Witnesses:   1 primary witness (18-year-old female security guard), with secondary reports of a blank television from a nearby farmhouse.

Summary: An 18-year-old woman saw a pair of bright “headlights” flashing from an oval object moving silently through the skies over Walcott, Iowa, where she worked as a security guard. Her radio and walkie-talkie stopped working, and cows and crickets in a nearby field stood silent. A television in a nearby farmhouse went blank, she learned later.

“Area ‘encounter’ defies explanation”
By Stacey Burling

She’s been laughed at, harassed and ridiculed, but the 18-year-old Davenport woman knows what she saw on that crisp, clear night last October. She declines to be identified for fear of jeopardizing future employment opportunities. What she saw, she says, was a pair of bright “headlights” flashing from an oval object moving silently through the skies over Walcott, Iowa, where she worked as a security guard.

GLIDING TOWARD HER as she manned a watchtower at the town’s French and Heeht plant, the disc obscured a flashing red beacon light on a grain elevator. Her radio and walkie-talkie stopped working, and cows and crickets in a nearby field stood silent. A light-sensitive mercury vapor lamp about 100 yards away. the woman went dark. A television in a nearby farmhouse went blank, she learned later.

“At first I wasn’t sure what it was, and I just sort of stood there and watched it,” she said.

She thought it was a helicopter until she realized it made no noise. Terrified, she stood frozen outside the guardhouse and watched, Then she went in search of other witnesses. When she returned, the object was gone.

BUT THE WOMAN says few people have believed her story. “They look at me like I’m nuts,” she says. “It’s like somebody telling you that they’d seen a green elephant.”

Her boss1 told her to report the incident to police, but she says the Davenport policeman in charge and three other officers “laughed hysterically” when she told her story. They did, however, call the Center for UFO Studies in Evanston, which connected her with DeGraw. Despite the widespread disbelief, she’s still convinced the sighting was not a mistake. “I know what I saw,” she says. “I’m not blind.”

Technical Analysis: The Mechanics of EM Interference

The Walcott sighting is a prime candidate for technical study due to the specific nature of the electrical failures reported. The simultaneous malfunction of a mercury vapor lamp, two-way radio, and television set suggests the presence of a powerful, localized electromagnetic field.

• Ionization and Light Failure: Mercury vapor lamps operate by creating an electric arc through vaporized mercury. A strong external electromagnetic field can disrupt this arc or interfere with the lamp’s light-sensitive photocell, causing the “blackout” witnessed 100 yards from the craft.

• RF Interference: The failure of the walkie-talkie and base station radio indicates Radio Frequency Interference (RFI). This occurs when an external source emits electromagnetic radiation that overpowers the signals used by communication devices, effectively “jamming” the equipment.

• The Oz Effect and Acoustics: The “silencing” of crickets and cattle—often called the Oz Effect—may have a technical basis. High-frequency electromagnetic fields or ultrasonic emissions can cause temporary disorientation or a “startle response” in animals, leading to the abrupt silence described by the witness.

• Luminous Source Classification: While initially classified as a Nocturnal Light (NL), the degree of physical interaction with the local power grid and electronic devices strongly supports a reclassification to Close Encounter of the Second Kind (CE-II).

Researchers Notes

• EM Interference: This case is highly significant due to the simultaneous failure of multiple electronic devices: a two-way radio, a walkie-talkie, a mercury vapor lamp, and a television set. This suggests a powerful electromagnetic field associated with the craft’s propulsion or power source.

• Biological Silencing: The report of cows and crickets falling silent is a classic “Oz Effect” indicator. Animals often sense ultrasonic frequencies or atmospheric changes before humans, leading to the eerie stillness described by the witness.

• Hynek Classification: Currently listed as NL (Nocturnal Light), but the physical effects on electronics and the environment could justify a reclassification toward CE-II (Close Encounter of the Second Kind).

• CUFOS Involvement: The referral to the Center for UFO Studies indicates that even if local police were dismissive, the Center’s researchers recognized the technical merits of the EM interference reports.

• Strategic Location: The French and Hecht plant was an industrial site. UFO sightings frequently occur near infrastructure, power grids, or industrial centers, possibly due to the electrical signatures these locations emit.

The Walcott encounter stands out for its high level of physical and environmental interaction, typical of a Close Encounter with significant energy output. While on duty in a watchtower, the witness observed a large oval object glide toward her, effectively obscuring a red beacon light on a nearby grain elevator. The most striking aspect was the absolute silence of the craft, which initially led the witness to rule out conventional aircraft like helicopters. The environmental “dead zone” created by the object—silencing crickets and cattle—suggests a localized atmospheric or electromagnetic effect that is frequently reported in high-credibility sightings from this era.

The aftermath of the sighting highlights the sociological challenges faced by UFO witnesses in the late 1970s. Despite the physical evidence of electrical failure (including a mercury vapor lamp going dark and home television interference), the witness was met with “hysterical laughter” from the Davenport police. This dismissive response nearly suppressed a report that included multi-point verification from electronic equipment failure and biological reactions. The case remains a compelling example of an unexplained aerial phenomenon impacting local infrastructure in rural Iowa.
