Here’s a fascinating essay on the Seattle Windshield Pitting Epidemic of 1954.
On April 15, 1954, Bellingham, Seattle and other Washington communities are in the grip of a strange phenomenon — tiny holes, pits, and dings have seemingly appeared in the windshields of cars at an unprecedented rate. Initially thought to be the work of vandals, the pitting rate grows so quickly that panicked residents soon suspect everything from cosmic rays to sand-flea eggs to fallout from H-bomb tests. By the next day, pleas are sent to government officials asking for help in solving what would become known as the Seattle Windshield Pitting Epidemic.
Stranger than fiction …
