Overview
A proposed review of archived White Sands ionogram records could offer a new way to investigate the atmospheric conditions surrounding the New Mexico “green fireball” reports of the late 1940s and early 1950s. Ionograms are records produced by ionosondes, instruments that measure the ionosphere by transmitting radio pulses and recording the altitude and density of reflecting layers. The records may reveal unusual changes in ionospheric conditions—or help determine whether reported aerial phenomena coincided with identifiable atmospheric disturbances.
The proposal focuses on reports associated with Los Alamos, Sandia and White Sands Proving Ground, locations central to the United States’ early nuclear-weapons and missile programs. It is important to note, however, that the available material presents the idea as a research proposal rather than a completed study. No results from an analysis of the ionogram archives are reported, and the records have not, on the basis of the supplied source, established a physical connection between the sightings and ionospheric activity.
Historical Context
The reports form part of a broader collection assembled by the National Investigations Committee on Aerial Phenomena (NICAP) under its “New Mexico Sightings” project. The project, updated September 3, 2005, argues that unusual aerial reports were repeatedly made near nuclear research, production and storage sites. Its coordinator, Francis Ridge, wrote that “the evidence for a UFO/Nuclear Connection grows stronger by the day,” citing government documents and reports from facilities including Los Alamos and Sandia Base.
That interpretation remains the project’s position rather than a demonstrated scientific conclusion. The records described on the site include material from the FBI, CIA, Army and Air Force, along with summaries from the Air Force Office of Special Investigations. NICAP says its collection includes the 209-case La Paz Catalog, also known as the AFOSI Summary of Sightings of Unknown Aerial Phenomena. According to the project, many entries concern New Mexico green-fireball reports, although the summaries are often brief and some cases lack complete supporting documentation.
The Green Fireball Reports
NICAP’s chronology places an early New Mexico report in March 1944, when an Air Force B-17 pilot near Carlsbad reportedly saw a fast-moving, glowing green object that illuminated the cockpit before disappearing over the horizon. The site lists a June 27, 1947, report by Capt. E.B. Detchmendy, who allegedly observed a white glowing object passing over the White Sands missile range.
Another account dated June 29, 1947, involves White Sands personnel and scientists traveling from Las Cruces toward the proving ground. The listed witnesses included Naval Research Laboratory rocket scientist-engineer Carl J. Zohn, NRL scientist Curtis C. Rockwood, Rockwood’s wife and White Sands technician John R. Kauke. The source describes them observing a rotating, silvery or shiny object, though the excerpt does not provide the full account.
Why Ionograms Matter
A systematic comparison of sighting times with ionograms could help separate possible environmental explanations from events that remain unexplained. Researchers could examine ionospheric height, electron density and disruptions linked to solar activity, rocket launches, radio interference or severe weather. Such a study would require reliable timestamps, geographic information, preserved instrument records and careful controls against ordinary variations in the upper atmosphere.
The historical files were assembled through contributions from researchers including Dan Wilson, Brad Sparks and Jean Waskiewicz, according to NICAP. Their catalogs may help identify candidate dates, but archival summaries alone cannot demonstrate causation. A scientifically useful investigation would need to publish its methods, account for incomplete records and compare the suspected dates with broader atmospheric and astronomical data. Until that work is completed, the White Sands ionograms represent a potentially valuable archive—not evidence that the green fireballs produced measurable ionospheric signatures.
