WWII soldiers get their last kiss before being deployed.
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
attempted takeover 1970
"Attempted takeover. During the Days of Concern in May of 1970, student demonstrators against the Vietnam war and military training attempted a takeover of the old World War II barracks-type building which accommodated Detachment 60 of the AFROTC. Although students did not get into this building on this occasion, another try was made two years later and demonstrators occupied the second floor of the building for a part of one day. Damage to the building was negligible and there was no violence during either the 1970 or the 1972 events.
