The Beginning or the End (1947)
Robert Walker: Colonel Jeff Nixon
Colonel Jeff Nixon : [as the "Enola Gay" is approaching Hiroshima, 0815 in the morning] 250,000 people down there are starting their day. City about the size of Dallas, Texas. In about one second it'll be wiped off the map. They'll never know what hit them.
Captain William S. Parsons U.S.N. : We've been dropping warning leaflets on them for ten days now. That's ten days more warning than they gave us at Pearl Harbor.
