PROJECT 10073 RECORD CARD — Sioux City, Iowa, 2 January 1954

This document contains a Project 10073 record card and associated correspondence regarding a UFO sighting reported on January 2, 1954, in Sioux City, Iowa. The report was prepared by 2nd Lieutenant Earle W. Stanley of the 521st Air Defense Group and forwarded to the Director of Intelligence at USAF Headquarters. The witness, a civilian and former member of the Army Air Corps, reported observing a green object with an orange tail, approximately one-third the size of the moon, while driving south on Highway 63. The observation lasted between two and three seconds at an elevation of 40-50 degrees. The official conclusion recorded on the card is that the event was a meteor sighting, noting a possible error in time and a potential association with a similar sighting in Omaha, Nebraska. The document also includes a letter from 'Flying Saucers International' dated January 10, 1954, addressed to the Ground Observer Corps in Knoxville, Tennessee, inquiring about vapor trails from jet aircraft observed over Seiverville, Tennessee, between January 2 and 4, 1954, which the organization suspected were in pursuit of a U.F.O./U.A.O. The military report includes detailed weather data for the Sioux City area at the time of the incident, confirming unlimited ceiling and visibility.
