Background

Beginning in late 1948, military personnel, scientists, and civilians across New Mexico reported striking green fireballs traversing the night sky. The sightings were concentrated near the Los Alamos and Sandia nuclear weapons facilities, raising immediate national security concerns during a period of intense Cold War tension.

Der Vorfall

Military personnel, scientists, and civilians reported green fireballs across New Mexico.

Sightings concentrated near Los Alamos and Sandia nuclear facilities.

This raised national security concerns amid Cold War tensions.

Untersuchung

Dr. Lincoln La Paz, a meteorite specialist at the University of New Mexico, investigated the phenomenon.

After extensive fieldwork, he concluded the objects did not behave like natural bolides.

Air Force established Project Twinkle in 1950, deploying optical tracking equipment at several sites.

Analyse

Dr. Lincoln La Paz found:
- Trajectories were far too horizontal.
- Velocities were unusually slow.
- No impact fragments or debris recovered despite systematic searches.

Project Twinkle operated for roughly two years but suffered from:
- Inconsistent staffing.
- Limited instrument availability.

Ergebnisse

Project Twinkle's final report classified results as inconclusive.

Origin of the fireballs left unresolved.

Conventional science attributes them to natural meteoric activity.

La Paz and colleagues maintained an artificial source was more consistent with data.

Significance

The green fireballs represented one of the earliest instances where anomalous aerial phenomena near nuclear facilities prompted a dedicated military investigation, establishing a pattern of government interest in UFOs linked to strategic defense sites that persists to the present day.
