The Genie, a 1.3-kton tactical nuclear weapon, becomes operational. It can be launched from a US Air Force fighter and is capable of destroying an entire squadron of Soviet bombers without necessarily hitting them directly. Within a 1.6-kilometer radius, it has a 92% probability of kill. Detonated at high altitude and at Arctic latitudes, it causes death by absorbed gamma radiation within 5 minutes. It produces a brilliant white flash and a huge circular cloud that begins to rise, forming a gigantic smoke ring in the sky. The radioactive fallout is negligible.
