From the earliest days of aviation, pilots have enjoyed a certain amount of glamour because of their apparent willingness to face danger in the skies (military or stunt pilots) or their ability to travel to exotic locales (airline and cargo pilots). During World War I and World War II, radio-controlled aircraft served as aerial torpedoes and aerial targets, roles that evolved into the development of cruise missiles, airborne decoys, and target drones. In the late 1940s and 1950s, drone aircraft were pressed into service for such tasks as flying through clouds of radioactive fallout from nuclear explosions to collect samples without endangering aircrews. In the 1960s, improvements in unmanned vehicle technology spawned development of tactical and strategic reconnaissance platforms. By the dawn of the 21st century, unmanned aircraft systems (UAS) – i.e., airplanes without pilots on board – were used more and more frequently for a variety of missions.

The subject matter first reviews the special geometric- and mass-scaling requirements for free-flight dynamic models. Limitations of the free-flight techniques are also reviewed. The discussion then presents a review of the history of the development of free-flight techniques by the NACA and NASA, including discussions of the physical characteristics of key facilities, the models used, and the approach to testing. The major portion of the book focuses on the applications of the techniques to generic configurations for general research as well as to specific aircraft and spacecraft configurations.

The third in a series of Adlard Coles highly practical, hands on, step-by-step photographic manuals, Replacing Your Boat's Electrical System fills a gap in the market for the DIY boat builder and repairer, and for owners of older second-hand boats. The electrical system on a boat is crucial for the operation of all manner of useful as well as critical equipment, yet a simple failure or weakness can render these systems inoperable. In older boats fatigued or damaged wiring can be problematical or even terminal, so Mike Westin shows ow to replace a boat's electrical system to ensure fault-free service.
