Intro.: A Moment in Time with Dan Roberts.

Content: The Trinity Test in the desert of New Mexico on July 16, 1945 had proven the design put together by Robert Oppenheimer's scientists and Captain Deak Parson's team of ordinance specialists. During the previous year, Parsons, anticipating its use, had been assembling the unit which would deliver the bomb. His choice to lead the group was Col. Paul W. Tibbets, Jr. a veteran bomber pilot. Tibbets squadron, at its heart fifteen B-29 bombers modified to carry and drop the new bombs, began secret rehearsals at Wendover Field in Utah in the Fall of 1944. They would test drop dummy bombs and send the results back to the headquarters of the Project at Los Alamos, New Mexico. Any needed modifications would be made and the testing would resume.
