Tunguska Event — Controlled Trajectory Debate 1908

The Tunguska explosion of June 30, 1908 — the largest impact event in recorded history — has generated persistent debate about whether the trajectory of the incoming object was consistent with a natural bolide or showed evidence of controlled flight. Russian scientist Alexei Zolotov published research suggesting the trajectory showed an anomalous correction inconsistent with a freely-falling body. The lack of recovered meteorite material and the unusual airburst characteristics have kept the event in the UAP-adjacent literature for over a century.
