Line-vortex Theory for Calculation of Supersonic Downwash
A bent lifting line and an unbent lifting line (horseshoe-vortex system) are used to compute downwash behind triangular wings. An unbent lifting line is used to compute downwash behind rectangular wings. The results are compared with the exact linearlized solutions.

Critical Issues in the History of Spaceflight
In March 2005, the NASA History Division and the Division of Space History at the National Air and Space Museum brought together a distinguished group of scholars to consider the state of the discipline of space history. This volume is a collection of essays based on those deliberations. The meeting took place at a time of extraordinary transformation for NASA, stemming from the new Vision of Space Exploration announced by President George W. Bush in January 204: to go to the Moon, Mars, and beyond. This Vision, in turn, stemmed from a deep reevaluation of NASA?s goals in the wake of the Space Shuttle Columbia accident and the recommendations of the Columbia Accident Investigation Board. The new goals were seen as initiating a "New Age of Exploration" and were placed in the context of the importance of exploration and discovery to the American experiences. (Amazon).
