Boeing's 737 is indisputably the most popular and arguably the safest commercial airliner in the world. But the plane had a lethal flaw, and only after several disastrous crashes and years of painstaking investigation was the mystery of its rudder failure solved. This book tells the story of how engineers and scientists finally uncovered the defect that had been engineered into the plane. One of its novel features is that it portrays the complex interaction of different experts and opposing interests in investigating and solving the mystery of this single crash.

The Boeing 737 has a history of rudder system-related anomalies, including numerous instances of jamming. A number of accidents and incidents were the result of the airplanes' unexpected movement of their rudders. During the course of the four and a half year investigation of the crash of USAir Flight 427 near Aliquippa, Pennsylvania, killing 132 people, the NTSB discovered that the PCU's dual servo valve could jam as well as deflect the rudder in the opposite direction of the pilots' input, due to thermal shock, caused when cold PCUs are injected with hot hydraulic fluid. This finally solved the mystery of sudden jamming of the rudders of this aircraft.

Based on a 15-year successful approach to teaching aircraft flight mechanics at the US Air Force Academy, this text explains the concepts and derivations of equations for aircraft flight mechanics. It covers aircraft performance, static stability, aircraft dynamics stability and feedback control.

On January 31, 2000, Alaska Airlines, Flight 261, a McDonnell Douglas MD-83, was on its way from Puerto Vallarta, Mexico, to Seattle, Washington, when suddenly the horizontal stabilizer of the plane jammed. While passengers were praying for their life, Captain Thompson and First officer Tansky tried to make an emergency landing in Los Angeles. They did not make it, the plane suddenly crashed into the Pacific Ocean, killing all 93 people aboard. The NTSB concluded that the failure of the horizontal stabilizer was caused by insufficient maintenance. In other words the crash of Alaska Airlines Flight 261 could have been avoided.

The immediate human toll of the 1994 Flight 427 disaster was staggering: all 132 people aboard died on a Pennsylvania hillside. The subsequent investigation was a maze of politics, bizarre theories, and shrouded answers. Bill Adair, an award-winning journalist, was granted special access to the five-year inquiry by the National Transportation Safety Board (NTSB) while its investigators tried to determine if the world's most widely used commercial jet, the Boeing 737, was really safe. Their findings have had wide-ranging effects on the airline industry, pilots, and even passangers. Adair takes readers behind the scenes to show who makes decisions about airline safety—and why.

Flying is an extremely safe way to travel. Fewer than 14,000 individuals perished in U.S. airline disasters during the twentieth century. In contrast, nearly three times as many people lose their lives in automobile accidents every year. Yet plane crashes have a tremendous impact on public perceptions of air safety in the United States. When a crash occurs domestically, media coverage is immediate and continuous. Government teams rush to investigate, elected officials offer condolences and promise to find the cause, and airlines and plane manufacturers seek to avoid responsibility. Regulations are frequently proposed in response to a particular incident, but meaningful change often does not occur. In The Plane Truth, Roger Cobb and David Primo examine the impact of high-visibility plane crashes on airline transportation policy. Regulation is disjointed and reactive, in part due to extensive media coverage of airline disasters. The authors describe the typical responses of various players—elected officials, investigative agencies, airlines, and the media. While all agree that safety is the primary concern in air travel, failure to agree on a definition of safety leads to policy conflicts. Looking at all airline crashes in the 1990s, the authors examine how particular features of an accident correspond to the level of media attention it receives, as well as how airline disasters affect subsequent actions by the National Transportation Safety Board, Federal Aviation Administration, and others. Three accidents are considered in detail: USAir flight 427 (September 1994), ValuJet flight 592 (May 1996), and TWA flight 800 (July 1996). The authors also discuss how the September 11 terrorist attacks turned attention away from safety and toward security. Cobb and Primo make several policy recommendations based on their findings. These include calling on lawmakers and regulators to avoid reactive regulation and instead to focus on systematic problems in a

In 1982, Argentina rashly gambled that a full-scale invasion of the Falkland Islands — ownership of which had been disputed with Great Britain for over a century — would put an end to years of political wrangling. However Britain’s response was to immediately dispatch a task force to recover the islands, by force if necessary. The ‘conflict’ which followed (a formal declaration of war was never given) lasted ten weeks from Argentine invasion to British liberation, the white heat of battle using 20th century technology contrasting with bitter hand-to-hand bayonet fighting in inhospitable conditions. Eyewitness accounts by the participants of both sides, and islanders, leave us in no doubt as to the ferocity of the combat on land, sea, and in the air. Comparison photography in color of all the battlefields, the crash sites of the aircraft shot down, the relics and the remains, together with portraits of those who lost their lives and the battlefield memorials, serve as a graphic testimony to their endeavors, 25 years after the battle. A Roll of Honour lists the casualties of both sides and, for the first time, the graves of all the British fallen — both on the islands and in the United Kingdom — have been visited and photographed as a lasting record of all those who made the supreme sacrifice.
