Historical context

The most physically aggressive wave on record. Luminous objects — locals called them 'chupa-chupa' (sucker-sucker) — descended nightly over fishing villages, projecting beams that left burns, puncture marks, anemia and lasting weakness; Dr. Wellaide Cecim Carvalho treated dozens. The Brazilian Air Force's Operação Prato, led by Captain Uyrangê Hollanda, documented the phenomena for months with photographs and reports, then shut down without explanation. Hollanda gave a detailed interview in 1997 confirming the operation and died by suicide months later — a coda that fuels the case's dark reputation. Files were declassified in stages from 2005.

Skeptical note

Proposed explanations (piranha-attack folklore repurposed, mass anxiety in isolated communities, misidentified lights) struggle with the medical records and the military documentation — even hardened skeptics rank Colares among the genuinely difficult cases.
