Book Description
In the long and proud history of flight research at what is now called the NASA Dryden Flight Research Center, the D-558 project holds a special place as being one of the earliest and most productive flight research efforts conducted here. Data from the D-558 and the early X-planes enabled researchers at what became NASA's Langley Research Center to correlate and correct test results from wind tunnels with actual flight values. Then, the combined results of flight and wind-tunnel testing enabled the U.S. aeronautical community to solve many of the problems that occur in the transonic speed range (about 0.8 to 1.2 times the speed of sound), such as pitch-up, buffeting, and other instabilities. This enabled reliable and routine flight of such aircraft as the century series of fighters (F-100, F-102, F-104, etc.) as well as all commercial transport aircraft from the mid-1950s to the present. The Douglas D-558-1 Skystreak and D-558-2 Skyrocket were, with the Bell XS-1, the earliest transonic research aircraft built in this country to gather data so the aviation community could understand what was happening when aircraft approached the speed of sound (roughly 741 miles per hour at sea level in dry air at 32 degrees Fahrenheit). In the early 1940s, fighter (actually, in the terms of the time, pursuit) aircraft like the P-38 Lightning were approaching these speeds in dives and either could not get out of the dives before hitting the ground or were breaking apart from the effects of compressibility—increased density and disturbed airflow as the speed approached that of sound and created shock waves.

Book Description
This official NASA history report provides a history of research with the D-558 Skystreak and Skyrocket supersonic airplane at NASA's Dryden Flight Research Center in California. In the long and proud history of flight research at what is now called the NASA Dryden Flight Research Center, the D-558 project holds a special place as being one of the earliest and most productive flight research efforts conducted here. Data from the D-558 and the early X-planes enabled researchers at what became NASA's Langley Research Center to correlate and correct test results from wind tunnels with actual flight values. Then, the combined results of flight and wind-tunnel testing enabled the U.S. aeronautical community to solve many of the problems that occur in the transonic speed range (about 0.8 to 1.2 times the speed of sound), such as pitch-up, buffeting, and other instabilities. This enabled reliable and routine flight of such aircraft as the century series of fighters (F-100, F-102, F-104, etc.) as well as all commercial transport aircraft from the mid-1950s to the present.At the symposia honoring the 50th anniversary of the D-558-1 Skyrocket's first flight in February 1948, four D-558 pilots -- Stanley P. Butchart, Robert A. Champine, A. Scott Crossfield, and John Griffith -- plus Air Force Historian Richard Hallion offered insightful comments and meaningful anecdotes that deserved a wider audience than the few hundred people who attended. To make their recollections and related documents available to such an audience, NASA is publishing this volume.The Douglas D-558-1 Skystreak and D-558-2 Skyrocket were, with the Bell XS-1, the earliest transonic research aircraft built in this country to gather data so the aviation community could understand what was happening when aircraft approached the speed of sound (roughly 741 miles per hour at sea level in dry air at 32 degrees Fahrenheit). In the early 1940s, fighter (actually, in the terms of the time, pursuit) aircraft like the P-38 Lightning were approaching these speeds in dives and either could not get out of the dives before hitting the ground or were breaking apart from the effects of compressibility--increased density and disturbed airflow as the speed approached that of sound and created shock waves.At this time, aerodynamicists lacked accurate wind-tunnel data for the speed range from roughly Mach 0.8 to 1.2 (respectively, 0.8 and 1.2 times the speed of sound, so named in honor of Austrian physicist Ernst Mach, who -- already in the second half of the 19th century -- had discussed the speed of a body moving through a gas and how it related to the speed of sound). To overcome the limited knowledge of what was happening at these transonic speeds, people in the aeronautics community -- especially the National Advisory Committee for Aeronautics (NACA), the Army Air Forces (AAF -- Air Force after 1947), and the Navy -- agreed on the need for a research airplane with enough structural strength to withstand compressibility effects in this speed range. The AAF preferred a rocket-powered aircraft and funded the XS-1 (experimental Supersonic, later shortened to simply X), while the NACA and Navy preferred a more conservative design and pursued the D-558, with the NACA also supporting the X-1 research.

Book Description
The prospectus of humans living, working, and establishing communities in space can no longer be dismissed as the romantic notions of science fiction writers and space buffs. With the launch of the space shuttle human kind will enter a new era in space exploration, one giant step closer to the goal of human colonization. Our understanding of man’s role in space is maturing, and the myths of life in space as a slick Buck Rogers episode or a scene from Star Wars must give way to a realistic plan for human life in other part of the solar system. We are ready now for a factual assessment of the challenges ahead: in Toward Distant Suns, the prospects of space exploration and space colonization have come of age. Here, for the first time, is a realistic look at what humankind must accomplish in order to colonize near space. Based on the most up-to-date research available, Toward Distant Suns tackles the problems of technology and lifestyle that will face those men and women whose mission is to settle space. Here is realistic, in-depth coverage of: space shuttle’s role in near space construction, development of new, more versatile rocket fuels and motors, building the large communications platforms, power satellites the “Space Spider,” and space colonies, the space workers—how they will be chosen, trained, and transported; life in zero-g—space tourism and space war; “suburbanizing” space earth dwellers; the real future of interstellar colonization Toward Distant Suns also takes a new look at the tantalizing question: What is our place in the galaxy? It reviews the Search for Extraterrestrial Intelligence experiments, the latest work on interstellar flight and colonization, and the current scientific information on planetary formation and humanoid development, to reach the startling conclusion: Mankind may be unique and along.
