Anomalous radar echoes in the Pacific off Ecuador

Summary

At 02:30 on 26 May 1979, two crew members aboard a ship north of Ecuador's Chimborazo volcano detected four sharply defined radar echoes on their V 22 radar that merged into a single return over two to three minutes. The echoes did not match known natural causes such as weather interference or structural multipath reflections from the vessel. Classified C by GEIPAN, the case does not fit neatly into conventional categories, though no robust alternative explanation has been offered either.
