How did the table fork acquire a fourth tine?  What advantage does the Phillips-head screw have over its single-grooved predecessor? Why does the paper clip look the way it does? What makes Scotch tape Scotch?   In this delightful book Henry Petroski takes a microscopic look at artifacts that most of us count on but rarely contemplate, including such icons of the everyday as pins, Post-its, and fast-food "clamshell" containers.  At the same time, he offers a convincing new theory of technological innovation as a response to the perceived failures of existing products—suggesting that irritation, and not necessity, is the mother of invention.

    During the lend-lease agreement with the USA, the RAF and Fleet Air Arm operated several American designs, each of which was tested to evaluate its potential.This book looks at the key area of fighter aircraft and includes the test results and pilot's own first-hand accounts of flying seventeen different models, designed in the UK, America and Germany. The reader will learn of the possibilities of air superiority offered by these types and also their weaknesses. Types included are The Hawker Hurricane, Supermarine Spitfire, Boulton Paul Defiant, Hawker Tempest and Typhoon, Bell Airacobra, Messerschmitt Bf 109, Focke-Wulf Fw 190, Brewster Buffalo, Curtiss Tomahawk, North American Mustang, Grumman Martlet, Republic Thunderbolt, and Vought Corsair. All aircraft that saw a great deal of action throughout the War and which are now part of legend.

    It is a book for those who were part of Apollo and want to recapture the experience and for those of a new generation who want to know how it was done. It is an opinion shared by many Apollo veterans. Republished in 2004 with a new Foreword by the authors.

    As recounted by Ben Rich, the operation's brilliant boss for nearly two decades, the chronicle of Lockheed's legendary Skunk Works is a drama of cold war confrontations and Gulf War air combat, of extraordinary feats of engineering & achievement against fantastic odds. Here are up-close portraits of the maverick band of scientists & engineers who made the Skunk Works so renowned. Filled with telling personal anecdotes & high adventure, with narratives from the CIA & from Air Force pilots who flew the many classified, risky missions, this book is a portrait of the most spectacular aviation triumphs of the 20th century.

    Probably no one felt more disappointment and regret than Allan McDonald, who had warned us not to launch that day. His story tells of loss, grief, and the eventual rebuilding and recovery."--Robert "Hoot" Gibson, former Space Shuttle pilot and commander   "A major contribution to a difficult episode in the history of human spaceflight."--Roger D. Launius, Division of Space History, Smithsonian Institution   “McDonald tells the heartbreaking tale of how he saw his words of warning ignored, and the fateful consequences of that decision.”--Donald C. Elder III, Eastern New Mexico University   On a cold January morning in 1986, NASA launched the Space Shuttle Challenger, despite warnings against doing so by many individuals, including Allan McDonald. The fiery destruction of Challenger on live television moments after launch remains an indelible image in the nation’s collective memory.   In Truth, Lies, and O-Rings, McDonald, a skilled engineer and executive, relives the tragedy from where he stood at Launch Control Center.  As he fought to draw attention to the real reasons behind the disaster, he was the only one targeted for retribution by both NASA and his employer, Morton Thiokol, Inc., makers of the shuttle’s solid rocket boosters. In this whistle-blowing yet rigorous and fair-minded book, McDonald, with the assistance of internationally distinguished aerospace historian James R. Hansen, addresses all of the factors that led to the accident, some of which were never included in NASA’s Failure Team report submitted to the Presidential Commission.  Truth, Lies, and O-Rings is the first look at the Challenger tragedy and its aftermath from someone who was on the inside, recognized the potential disaster, and tried to prevent it. It also addresses the early warnings of very severe debris issues from the first two post-Challenger flights, which ultimately resulted in the loss of Columbia some fifteen years later.

    As the Wrights labored to invent the airplane, Zeppelin fathered the wondrous airship, sparking a bitter rivalry between the two types of aircraft and their innovators that would last for decades in the quest to control one of humanity's most inspiring achievements.And it was the airship -- not the airplane -- that would lead the way. In the glittery 1920s, the count's brilliant protégé, Hugo Eckener, achieved undreamt-of feats of daring and skill, including the extraordinary Round-the-World Voyage of the Graf Zeppelin. At a time when America's airplanes -- rickety deathtraps held together by glue, screws, and luck -- could barely make it from New York to Washington, Eckener's airships serenely traversed oceans without a single crash, fatality, or injury. What Charles Lindbergh almost died doing -- crossing the Atlantic in 1927 -- Eckener effortlessly accomplished three years before the Spirit of St. Louis even took off. Even as the Nazis sought to exploit Zeppelins for their own nefarious purposes, Eckener built his masterwork, the behemoth Hindenburg -- a marvel of design and engineering. Determined to forge an airline empire under the new flagship, Eckener met his match in Juan Trippe, the ruthlessly ambitious king of Pan American Airways, who believed his fleet of next-generation planes would vanquish Eckener's coming airship armada.It was a fight only one man -- and one technology -- could win. Countering each other's moves on the global chessboard, each seeking to wrest the advantage from his rival, the two men's struggle for mastery of the air was not only the clash of technologies, but of business, diplomacy, politics, personalities, and their vastly different dreams of the future.Empires of the Sky is the sweeping, untold tale of the duel that transfixed the world and helped create our modern age.

    Alydar, all muscle with a fearsome closing kick, was already the popular favorite to win the Kentucky Derby. Affirmed, deceptively laid-back streamlined elegance, was powered forward by his steely determination not to settle for second place. In the Sport of Kings, the Triple Crown is the most valued prize, requiring a horse to win not just one race, but three: the Kentucky Derby, the Preakness Stakes, and the Belmont Stakes. And 1978 would not be just for the record books, but also one of the greatest dramas ever played out in the racing world. There were names to conjure with, worthy of the Sport of Kings. The bloodline of Native Dancer. The teen wonderboy jockey Steve Cauthen. The once unbeatable Calumet Farm—the Damn Yankees of the racing world—now in eclipse and hoping for a comeback. The newcomer Harbor View Farm—owned by brash financier Louis Wolfson, who wouldn’t let even a conviction and a prison sentence for securities violations stand in the way of his dreams of glory. And the racetracks themselves: Belmont, Saratoga, Pimlico. And, of course, Churchill Downs. It has been thirty-five years since Affirmed and Alydar fought for the Triple Crown, thirty-five years when no other horse has won it. Duel for the Crown brings this epic battle to life. Not just two magnificent Thoroughbreds but the colorful human personalities surrounding them, caught up in an ever-intensifying battle of will and wits that lasted until the photo finish of the final Triple Crown race . . . and Alydar and Affirmed leaped into the history books.

    Increasingly, the decisions that affect our lives--where we go to school, whether we can get a job or a loan, how much we pay for health insurance--are being made not by humans, but by machines. In theory, this should lead to greater fairness: Everyone is judged according to the same rules.But as mathematician and data scientist Cathy O'Neil reveals, the mathematical models being used today are unregulated and uncontestable, even when they're wrong. Most troubling, they reinforce discrimination--propping up the lucky, punishing the downtrodden, and undermining our democracy in the process.

    Introduction to Flight blends history and biography with discussion of engineering concepts, and shows the development of flight through this perspective.
