Reach for the Sky: The Story of Douglas Bader, Legless Ace of the Battle of Britain (Bluejacket Books) (Paperback)


A "gut" book in which intestinal fortitude is the answer to a life without legs. Douglas Bader lost both of his in an airplane crash, nearly died in the operations following it, determined he would walk on his artificial legs without a cane - and did - and managed to return to the British Air Force. When the Air Ministry "retired" him, he made the best of civilian life but when World War II broke, Bader was back in a flash and quickly built himself a reputation which eventually carned him his own squadron.

Flying, fighting, his example was an inspiration to all the men, his score of Me's mounted and when he was taken prisoner, his spare leg was flown over to him. He managed one escape, and with the war's end has continued his career in the clouds.....It's quite a story and it never forgets the amazing and sensitive support given by his wife, Thelma, whose understanding complemented his courage and determination. Something. (Kirkus Reviews) --This text refers to an out of print or unavailable edition of this title.

Douglas Bader was a legend in his lifetime. After losing both legs in an air crash in 1931 and being dismissed as a cripple by the Royal Air Force, he fought his way back into the cockpit of a Spitfire to become one of the great heroes of the Battle of Britain. This inspiring biography of the famous World War II fighter pilot, first published in 1954, has a following of faithful readers who come back to the book time and again to re-read, share with their children and pass along to friends.

Not many books have made such an impact on people's lives. Bader's story is so extraordinary that no one would dare invent it, and Brickhill succeeds in matching the excitement of Bader's war deeds with the triumph of his greater battle over a severe handicap. Told he would never walk without a cane, Bader learned to dance, swim, golf, and play tennis. Told he would never fly again, he became not only one of the RAF's top combat pilots but a squadron leader and innovator of fighter tactics that helped win the Battle of Britain. Among the thrilling incidents chronicled in the book are Bader's first successful encounter with an enemy plane, his own shoot down, and his succession of escapes from German prisons.

Radar

Radar is a system that uses electromagnetic waves to identify the range, altitude, direction, or speed of both moving and fixed objects such as aircraft, ships, motor vehicles, weather formations, and terrain. The term RADAR was coined in 1941 as an acronym for radio detection and ranging. The term has since entered the English language as a standard word, radar, losing the capitalization. Radar was originally called RDF (Radio Direction Finder) in the United Kingdom.

A radar system has a transmitter that emits either microwaves or radio waves that are reflected by the target and detected by a receiver, typically in the same location as the transmitter. Although the signal returned is usually very weak, the signal can be amplified. This enables radar to detect objects at ranges where other emissions, such as sound or visible light, would be too weak to detect. Radar is used in many contexts, including meteorological detection of precipitation, measuring ocean surface waves, air traffic control, police detection of speeding traffic, and by the military.

E-3 Sentry

The Boeing E-3 Sentry is an American military airborne warning and control system (AWACS) aircraft that provides all-weather surveillance, command, control and communications, to the United States, United Kingdom, France, Saudi Arabia, and NATO air defense forces. Production ended in 1992 after 68 had been built.

The E-3 Sentry is a modified Boeing 707-320B Advanced commercial airframe. Modifications included a rotating radar dome, single-point ground, and air refueling points. The dome is 30 feet (9.1 m) in diameter, six feet (1.8 m) thick at the center, and is held 14 feet (4.2 m) above the fuselage by two struts.

The dome weighs approximately 1.5 tons and provides 1.5 tons of lift. It contains a hydraulically rotated antenna system that permits the AN/APY-1/2 passive electronically scanned array radar system to provide surveillance from the Earth's surface up into the stratosphere, over land or water. Generators on each of the four engines provide the one megawatt of power required by the radar. The Pulse Doppler radar has a range of more than 250 miles (400 km) for low-flying targets at its operating altitude (essentially to the radar horizon), and the Pulse(BTH) beyond the horizon radar has a range of approximately 400 miles (650 km) for aerospace vehicles flying at medium to high altitudes (essentially above the radar horizon). The radar combined with an SSR subsystem can look down to detect, identify and track enemy and friendly low-flying aircraft by eliminating ground clutter returns.
