U.S. Windshield Pitting Mystery (1954)

In 1954, residents of several U.S. states, notably Washington, faced a puzzling phenomenon as car windshields inexplicably developed pits. Blamed on top-secret nuclear testing, rumors circulated about the H-bomb fallout causing the damage, with theories ranging from airborne marine creatures to acid-laced bugs eroding the glass. The reports eventually ceased by the end of the summer, leaving the mystery unresolved.
