    Since the founding of the Dryden Flight Research Center History Office in 1996, its staff has conducted nearly a hundred interviews with retired and serving employees. Their recollections represent a unique resource in understanding the development of aerospace technology in the second half of the 20th century. Their personal experiences, insights, and opinions allow the reader to gain an understanding into what it was actually like to have been involved with some of the milestone events in aerospace history. These interviews have been edited and assembled into this monograph, so that a wider audience can also share in their experiences. This study covers the early years of what eventually became the Dryden Flight Research Center. It spans the period between the arrival of Walter Williams and the first group of NACA engineers at Muroc in 1946, and ends with the establishment of NASA in 1958. This timeframe encompasses the breaking of the sound barrier, the pivotal inertial coupling research, the first use of computer simulations, the transformation of the NACA facility from a pair of old hangars into a state-of-the-art research center, and the dawn of the space age. These events took place against the background of the end of World War II, the start of the Cold War, and the twin technological revolutions of jet propulsion and supersonic flight. They are told by the people who participated in these events, in their own words.

    During an aerospace engineer's undergraduate studies, he or she will attend classes in aerodynamics, thermodynamics, structures, stability and control, dynamics, design, propulsion, and computer science, along with the related courses in mathematics, physics, statistics, and chemistry required to understand the material. Upon graduation, the new engineer will have acquired a basic knowledge of how to build an aerospace vehicle.

    During an aerospace engineer's undergraduate studies, he or she will attend classes in aerodynamics, thermodynamics, structures, stability and control, dynamics, design, propulsion, and computer science, along with the related courses in mathematics, physics, statistics, and chemistry required to understand the material. Upon graduation, the new engineer will have acquired a basic knowledge of how to build an aerospace vehicle. What only comes through experience, however, is the understanding of the inevitable imperfect process through which an aerospace vehicle is built. This is the adventure of turning a basic concept into functional hardware. Engineers working on a project must often deal with ambiguous situations. They are routinely asked by management to provide risk assessments of a project, yet even after careful analysis uncertainties remain. The project must be accomplished within finite limits of time and money. The question an engineer answers is whether the solution to potential problem is worth the cost and schedule delay, or if the solution might actually be worse than the problem it is meant to solve. Review protocols are established to ensure that an unknown has not been overlooked. But these cannot protect against an unknown unknown.
