Two-volume collection of case studies on aspects of NACA-NASA research by noted engineers, airmen, historians, museum curators, journalists, and independent scholars. Explores various aspects of how NACA-NASA research took aeronautics from the subsonic to the hypersonic era.-publisher description.

With the development of supersonic aircraft, the X-plane era ushered in a new and challenging phase of flight. Researchers found that much of the knowledge accumulated from the previous, subsonic flight era did not apply to the emerging supersonic aircraft. These turbojet-powered planes also outpaced the usefulness of the wind tunnel, previously an indispensible tool of aeronautic research.This book explores the development of the X-series research aircraft, the planes that helped bridge the gap between subsonic flight and hypersonic flight.

Apollo 11 astronaut Buzz Aldrin’s courageous, candid memoir of his return to Earth after the historic moon landing and his personal struggle with fame and depression. “We landed with all the grace of a freight elevator,” Buzz Aldrin relates in the opening passages of Return to Earth, remembering Command Module Columbia’s abrupt descent into the gravity of the blue planet. With that splash, Aldrin takes readers on a journey through the human side of the space program, as one of the first two men to land on the moon learns to cope with the pressures of his new public persona. In honest and compelling prose, Aldrin reveals a side of instant fame for which West Point and NASA could never have prepared him. One day a fighter pilot and engineer, the next a cultural hero burdened with the adoration of thousands, Aldrin gives a poignant account of the affair that threatened his marriage, as well as his descent into alcoholism and depression that resulted from trying to be too many things to too many people. He didn’t realize that when he landed on his home planet his odyssey had just begun. As Aldrin puts it, “I traveled to the moon, but the most significant voyage of my life began when I returned from where no man had been before.” Return to Earth is a powerful and moving memoir that exposes the stresses suffered by those in the Apollo program and the price Buzz Aldrin paid when he became an American icon.

This book describes the history of the NASA Ames 40- by 80-Foot and 80- by 120-Foot Wind Tunnels and is organized in four parts: Design and Construction; Operation and Management History; Research History; and Concluding Remarks, References, and Appendices.
