When the heat gets turned up in a conflict, support helicopter pilots are called upon to bring in additional troops and equipment or even provide battle support from the air. In modern warfare, the helicopter's agility and hovering ability have made it indispensible to the army, navy, air force, and marines for tactical support. This book describes the different missions support helicopter pilots undertake and the dangerous circumstances they must usually fly under.
Piloting experimental aircraft is more dangerous than most other types of flying. Test pilots are generally military aviators who fly new and modified aircraft, allowing the results to be measured and the design to be evaluated. In the 1950s, test pilots were being killed at the rate of about one a week, but the risks have shrunk to a fraction of that, thanks to the sophistication of aircraft technology, better ground-testing, and simulation of aircraft performance. Despite their image as fun-loving daredevils, these pilots have to be ruthlessly precise and professional when flying. This intriguing book looks at what type of people become test pilots, how they train, what the job includes, how it feels to be the first person to fly a new design, the aircraft they fly, and how they analyze and report on each flight.
The mind is a powerful instrument. It influences everything we do and say. We all talk about a sixth sense, or ESP. This book examines mind over matter, looking at claims that brain power alone can bend spoons, identify things without having seen them, or even read the minds of astronauts!
More than 2,300 years ago, the Greek philosopher Plato wrote about a glorious ancient city that sank without trace beneath the waves. Ever since that time people have wondered where this lost city, Atlantis, might be and whether it actually existed. Students will thrill as they learn about the different theories of, and search efforts for, this mythical city.
These army pilots fly the most demanding helicopter in existence, a machine so complex to operate that its known as Riding the Dragon. Only 3% of existing army helicopter pilots qualify to fly it. Trainees have to learn to train their eyes to work independently of each other while the right eye sees flight and weapons information in the helmet's monocle, the left eye is free to look outside the aircraft and scan for threats and other obstacles. And, flying the helicopter is only half the battle - its purpose is to provide firepower from the air to protect soldiers on the ground. This book lifts the lid on what life is like for these men and women: their training; the aircraft; the missions, and what its actually like to be under fire while flying.
