In late nineteen forty-eight, pilots, security personnel, and scientists reported brilliant green fireballs over New Mexico. The reports reached officials responsible for some of America's most sensitive atomic installations. Meteor expert Lincoln LaPaz investigated, witnessed a fireball himself, and brought his findings to a secret conference at Los Alamos.
The Air Force eventually built Project Twinkle to obtain photographs, trajectories, and other measurements. This episode follows the sightings across the atomic Southwest, reconstructs the investigation from surviving records, and examines why the program left so much unsettled.
