This coauthored review surveys reported aerospace and undersea phenomena, historical cases and proposed research. Selected figure pages distinguish drawings, photographs, material reports and hypothetical interpretations. Its coauthors and reproduced cases do not supply independent verification of underlying events, anomalous materials or government programmes.
