In 1956, a research organization called Aviation Studies International published a declassified Air Force report surveying electrogravitic propulsion programs at fourteen major U.S. aerospace contractors. The report called it one of the most significant areas of aerospace development at the time of writing. In 1957, the public record stopped. No papers. No patents. No published null results. No concluded program documentation. No official explanation.

More than a dozen researchers tied to NASA, nuclear propulsion, and classified defense programs are dead or missing. The FBI is investigating. Congress has used the word sinister. And one city appears again and again in the timeline.
