A boy and his Dog, 1945
Trinity, July 16th 1945
The first nuclear explosion in history took place in New Mexico at the Alamogordo test range in the Jornada del Muerto (journey of Death) desert.
"In that brief instant in the remote New Mexico desert the tremendous effort of the brains and brawn of all these people came suddenly and startlingly to the fullest fruition. Dr. Oppenheimer, on whom has rested a very heavy burden, grew tenser as the last seconds ticked off. He scarcely breathed. He held on to a post to steady himself. For the last few seconds, he stared directly ahead and then when the announcer shouted "Now!" and there came a tremendous burst of light followed shortly thereafter by the deep growling roar of the explosion, his face relaxed into an expression of tremendous relief. Several of the observers standing back of the shelter to warch the lighing effects were knocked flat by the blast.
…All seemed to feel that they had been present at the birth of a new age — The Age of Atomic Energy — and felt their profound responsibility to help in guiding into the right channels the tremendous forces which had been unlocked for the first time in history.”
Brigadier General Thomas F. Farrell, describing his impressions at S-10,000 a bunker 10,000 yards south of Trinity
