Elisardo Urrutia aircraft-window photographs

Official source account — 2018 annual report, printed page 28: Elisardo Urrutia found two apparent objects in photographs taken during a flight over Puerto Iguazú on 18 April 2018. Although initially reported as absent in following frames, CEFAE found them in more than one image, maintaining positions relative to parts of the aircraft. Their contrast and appearance led the agency to propose small scratches or impact pits in the acrylic window, rather than objects flying outside. The summaries distinguish reported observations from the agency’s proposed explanations. Source Type A/B ratings describe explanatory confidence and are not encounter classes.
