Benson<\/strong><\/h2>\n\n\n\n<p>On a hot and humid July day in 2003, a pair of small supersonic jet airplanes took off together from Cecil Field, a former naval air station on the eastern edge of Jacksonville, FL. Even though the Northrop Corporation had built both planes based on a common design, it was hard at first glance to tell that the two aircraft flying side by side were so closely related. One was a sleek T-38 Talon, a two-seat aircraft that has served as the U.S. Air Force\u2019s (USAF\u2019s) advanced trainer since the early 1960s. The other was originally an F-5E Tiger II, one of more than 2,000 Northrop F-5s that had equipped air forces around the world with a low-cost, high-performance combat and reconnaissance aircraft. Because of the F-5E\u2019s agility and compact size, the U.S. military adopted it as an aggressor aircraft to hone the skills of its own fighter pilots. Both planes attested to the competence of Northrop\u2019s design teams. Of all of the many supersonic jets developed for the Air Force and U.S. Navy in the 1950s, the T-38 and F-5 are the only ones still in general use.<\/p>\n\n\n\n<p>Although on loan from the Navy\u2019s aggressor training squadron, this particular F-5E no longer looked much like a fighter jet. With what appeared to be a pouch hanging under its chin, the aircraft somewhat resembled an overgrown pelican. In addition to lettering identifying Northrop Grumman Integrated Systems, its white fuselage was decorated with sharply angled blue and red pinstripes along with emblems containing the acronyms \u201cNASA\u201d and \u201cDARPA\u201d while its tail bore an oval logo with the letters \u201cQSP.\u201d<\/p>\n\n\n\n<p>At each of these stops, the planes attracted the attention of flight-line personnel and others nearby, most of whom could recognize the strange white jet as some kind of F-5. But many of them still had questions. What\u2019s with the big nose? Why is Boeing helping a Northrop Grumman pilot fly across the country? What do those jagged red and blue stripes signify? And why all the various logos?<\/p>\n\n\n\n<p>Quieting the Boom: The Shaped Sonic Boom Demonstrator and the Quest for Quiet Supersonic Flight is the story of this plane, as well as a general history of sonic boom research, emphasizing the people and organizations. The Shaped Sonic Boom Demonstrator culminated four decades of study and research on mitigating the strength of sonic booms.<\/p>\n\n\n\n<p>This book follows up on a case study from 2009, \u201cSoftening the Sonic Boom: 50 Years of NASA Research.\u201d That relatively short survey was published in volume I of NASA\u2019s Contributions to Aeronautics (NASA SP-2010-570, available at <a
