An area of the air base was set aside for public viewing of the landing, and crowds numbered well over 200,000 people, with some estimates as high as 300,000 visitors who flocked to the site.
James Young, Chief Historian of the Air Force Flight Test Center at Edwards AFB, remembered the landing well. "You just had to be there to hear, even feel, the double crack of the sonic boom," Young said. "It was such a tremendous sense of excitement to see something never seen before, to witness such a historic event."
