The Drifting Diamond of the Andes: Electromagnetic Interference Incident
Summary
On May 12, 2015, late at night, a freight train traveling through the Andean foothills near Puente del Inca, Mendoza Province, Argentina, experienced sudden instrument malfunction. The engineer reported witnessing a large, dark, diamond-shaped object hovering low above the train, which emitted no light. The object was silent and caused severe electromagnetic interference with the train's electronic systems. This incident highlights the unexplained nature of similar silent aerial phenomena and their impact on electromagnetic fields reported in the region.
Details
At 01:35 AM (UTC-3) on May 12, 2015, the freight train 'Los Andes,' traveling approximately 15 km southwest of Puente del Inca in Mendoza Province, experienced an abrupt failure of its dashboard instruments. Simultaneously, unstable fluctuations in the locomotive's power supply occurred, and the engine sound temporarily decreased. Engineer Juan Garcia observed a massive object moving parallel to the train in his line of sight. He testified the object was black or dark gray, perfectly diamond-shaped, emitted no light, and produced no sound. Its immense size ruled out the possibility of a natural phenomenon or a known aircraft. The authorities took this report seriously from the outset and initiated a detailed investigation.
Similar unidentified aerial phenomena have been reported in this Andean foothills region in the past. Local cattle ranchers have long recounted stories of peculiar 'shadow boats' gliding silently through the night sky during their nocturnal grazing. These anecdotal accounts, though fragmented, share common characteristics: 'silence,' 'distinctive shape,' and an 'awe-inspiring presence.' More recently, in 2008 and 2012, reports of brief but inexplicable noise interfering with small aircraft radio communications were recorded. However, none of these reports were accompanied by concrete physical evidence, hindering further investigation.
The Authority's investigation team conducted electromagnetic environment measurements at the incident site, analyzed the train's black box data, and performed detailed interviews with the engineer and other relevant parties. The train's operational recorder explicitly documented an intense, broadband electromagnetic noise spike occurring momentarily during the time the engineer witnessed the object—a surge far beyond what typical instrument malfunctions would produce. This noise also temporarily affected communication systems around the train. However, no landing marks or crash evidence was found on the ground. This discrepancy creates a clear contradiction with the observed phenomenon.
Testimonies from multiple witnesses consistently described the object as 'diamond-shaped.' However, there were slight variations in individual accounts regarding its precise size and surface coloration. Some witnesses stated the object seemed to absorb ambient light, while others perceived a faint glow around its edges. Whether this discrepancy stems from differing observation conditions or changes in the object's inherent properties remains unknown. Furthermore, the local power grid's remote monitoring system recorded an extremely brief but inexplicable voltage drop, synchronized with the incident time. This suggests the object may have somehow influenced ambient energy.
The Authority thoroughly examined whether the observed phenomenon could be explained by known natural events or man-made objects. However, the combination of the scale of electromagnetic interference and the appearance of a silent, distinctively shaped flying object was deemed unexplainable by known physical laws or aeronautical technology. Particularly, the absence of any physical traces on the ground further underscores the unique nature of this incident.
The investigation continued, but no new evidence emerged. In March 2016, the Authority classified the incident as 'unexplained' and transitioned to continuous monitoring. Since then, sporadic reports of minor electromagnetic anomalies and sightings of silent aerial objects continue to be reported in the region. The Authority collects this information, analyzing potential correlations for future understanding. Further large-scale observation and new insights into unidentified phenomena are indispensable for resolving its cause.

Witness Testimony
Engineer Juan GarciaSuddenly, all instruments went haywire. In my sight, that huge shadow floated silently. Its shape was a perfect diamond. I remember my body stiffening in fear.
Cattle Rancher Ernesto (anonymous)That is the 'Night Boat.' Ancestors have said it appears in the mountains. It doesn't glow, just a shadow that absorbs darkness. Untouchable, yet undeniably there.
Authority Investigator (anonymous)Electromagnetic anomaly data is conclusive. Yet, there are absolutely no physical traces. This is a clear contradiction. It's unexplainable with conventional investigation methods.
Kyu's Analysis
Unexplainable electromagnetic interference and lack of physical traces suggest a phenomenon beyond known laws. Continuous monitoring and data collection are essential.
