Oral history interview with Gaelan Felt conducted by Perry Kaufman in approximately 1975 for the Ralph Roske Oral History Project on Early Las Vegas. In this interview, Felt describes working at the Nevada Test Site and the effect the site had on Las Vegas, Nevada. Felt explains why Nevada was chosen as the location for the site, how they tested nuclear weapons, and how the local residents responded to the tests with varying levels of concern. He also talks about other aspects of the test site's history, such as workers' housing, and how Las Vegas has developed and changed.
