Peter W. Merlin: Tonopah Test Range. Arcadia Publishing, 2021, ISBN 978-1-4671-0579-8, S.7 (google.de): „The test complex was inaugurated in February 1957 with drop tests of two nuclear weapon shapes from bombers operating out of Kirtland Air Force Base, New Mexico. These missions demonstrated that Tonopah Test Range (TTR), which later appeared on AEC maps as Area 52, was more than adequate for high- and low-altitude bombing operations.“
