    In 1979, Thatcher's Britain was a country crippled by strikes, joblessness, and economic gloom, divided by race and class—and skanking to a new beat: 2 Tone. The unruly offspring of white boy punk and rude boy ska, the Specials burst on to the scene. On stage they were electric, and at the heart of this energy was the vocal chemistry of the ethereal Terry Hall and Jamaican rude boy Neville Staple. In 1961, five-year-old Neville was sent to England to live with his father, a man for whom discipline bordered on child abuse. As he recounts here, growing up black in the Midlands of the 1960s and 1970s wasn't easy, and his youth was marked by scuffles with skins, compulsive womanizing, and a life of crime that led from shoplifting to burglary and eventually prison. But throughout there was music, and Nev reveals how he became part of the most important band of the 1980s. He remembers sound system battles; the legendary 2 Tone tour with the Selecter, Madness, and Dexy's, and their clashes with white nationalist thugs. He recalls the band's increasing tensions and eventual split; his subsequent foray into bubblegum pop with Fun Boy Three; and a newfound fame in America as godfather to Third Wave ska bands. Finally he reflects on the Specials' reunion and how even now, 30 years later, they can't help tearing themselves apart.

    From the early tragedies of the Comet and the DC10 to the modern-day horror of the Concorde catastrophe in Paris and the mysterious loss of an Air France Airbus over the Atlantic, Faith painstakingly recreates the accidents, explains what went wrong and discusses how they can be prevented from recurring.

     And The Fool has one rule: No one leaves The Carnival. Ever. Christopher, the latest arrival thrust reluctantly through the gates, is certain that he doesn't belong there, and he's damn sure he's not staying. To have any chance of escaping, he must confront not only The Fool, but his own dark past.

    " Fox has inspired millions of people over the past forty years through his simple, practical guidelines. In Diagrams for Living he presents valuable keys to living a more fulfilled life drawn from the eloquent spiritual wisdom of the Bible.If we read the Bible literally, cautions Fox, we miss the eternal power and personal relevance found in its symbols, allegories, and parables. "Whether you realize it or not," he writes, "you are on every page from Genesis to Revelation." Fox shows how to read dramatic biblical stories as symbolic diagrams for living that can "show you how to overcome difficulties and problems, and how to give expression to the deep aspirations that lie hidden in your soul." This power to reveal, inspire, and guide makes the Bible's teachings adaptable to everyone at every stage of spiritual development.Sensible, contemporary, and full of reassurance, Diagrams for Living offers sage counsel from a gifted teacher.

    But that safety continues to be tested – and, occasionally, found wanting – by pilot error, freak weather conditions, poor maintenance and sheer bad luck. As ever, the lessons learned are painful.From the passengers sucked to their deaths from a gaping hole in a United Airlines Boeing 747 over Hawaii, to the astonishing escape of most of those aboard the Airbus which crashed into a forest at Mulhouse, to the insane decision of an Aeroflot captain to allow his young children to ‘fly’ his laden passenger jet over the Siberian wastelands, award-winning aviator writer Macarthur Job looks at what went wrong, and how it can be prevented from happening again.With photographs, and detailed illustrations by aviation artist Matthew Tesch, 'Air Disaster 3: Terror In The Sky' is a classic of its genre.Look out for two other books in Macarthur Job's Air Disaster series:Air Disaster 1: The Propeller EraAir Disaster 2: The Jet Age

    A part fails and your helicopter comes apart in flight, or, another aircraft runs into you and the pieces of both fall to the ground below, or the enemy gunner pulls the trigger at just the right moment and his rounds find your aircraft in exactly the right spot to take it out of the sky. Whichever way it happens, it wasn t your day. Which is why, after 24 years and over 5,000 flight hours with four armed services, Major Robert Curtis was so surprised at being alive when he passed his retirement physical. Starting with enlisting in the Army to fly helicopters during Vietnam, and continuing on through service with the National Guard, Marine Corps and Royal Navy, he flew eight different helicopters from the wooden-bladed OH-13E, through the Chinook, SeaKnight and SeaKing, in war and peace around the world. During that time over 50 of his friends died in crashes, both in combat and in accidents, but somehow his skill, and not an inconsiderable amount of luck and superstition, saw him through. His flying career began with a misbegotten strategy for beating the draft by enlisting. With the Vietnam War raging full blast in 1968 the draft was inevitable, so he wanted to at least get some small measure of control of his future. Although he had no thought of flying when he walked into the recruiting office, he walked out signed up to be a helicopter pilot. What he did not know was that 43% of all the aircraft sent to Vietnam were destroyed in combat or accidents. Soon he was in the thick of the war, flying Chinooks with the 101st Airborne. After Vietnam he left the Army, but kept flying in the National Guard while going to college. He was accepted at two law schools, but flying is addictive, so he instead enlisted in the USMC to fly some more. Over the next 17 years he would fly around the world off US and British ships from Egypt to Norway and all points in between. His engaging story will be a delight to all aviation enthusiasts.REVIEWS one of those books that you read that gives you the feeling of Deja Vu, and makes the hairs on the back of your neck riseNeall Ellis Robert Curtis gives us a compelling account of his exemplary service in wartime and beyond. The combat missions he flew out of Phu Bai/Camp Eagle in Vietnam did so much for so many, and remain alive and meaningful for all of us today.

    Cave paintings of the giant beasts hint at the profound role they played in early human culture-our Ice Age ancestors built igloo-shaped huts out of mammoth bones and even feasted on mammoth tongues. Eager to uncover more clues to this mystical prehistoric age, explorers since the time of Peter the Great have scoured Siberia for mammoth remains. Now a new generation of explorers has taken to the tundra. Armed with GPS, ground-penetrating radar, and Soviet-era military helicopters, they seek an elusive prize: a mammoth carcass that will help determine how the creature lived, how it died-and how it might be brought back to life.In this adventure-filled narrative, science writer Richard Stone follows two teams of explorers-one Russian/Japanese, the other a French-led consortium-as they battle bitter cold, high winds, supply shortages, and the deeply rooted superstitions of indigenous peoples who fear the consequences of awakening the "rat beneath the ice." Stone travels from St. Petersburg to the Arctic Circle, from the North Sea to high-tech Japanese laboratories, as he traces the sometimes-surreal quest of these intrepid scientists, whose work could well rewrite our planet's evolutionary history. A riveting tale of high-stakes adventure and scientific hubris, Mammoth is also an intellectual voyage through uncharted moral terrain, as we confront the promise and peril of resurrecting creatures from the deep past.

    The McGann's passionate and insightful writing evokes the raucous cast of riders, promoters, and journalists thrusting through highs and lows worthy of opera. This volume stands out as a must-read book for anyone seeking to appreciate cycling's race of races." -Peter Joffre Nye, author of The Six-Day Bicycle Races: America's Jazz Age Sport and Hearts of Lions "There are LOTS of books on the Tour de France. An increasing number of them are actually written in English. However, of those, none educates Americans about this grand spectacle�s rich past. The Tour de France has a history as fascinating and sordid as Rome�s and it is high time someone undertook to explain this to our American sensibility. Our guide for the trip is a man with a ravenous appetite for both world history and bicycle racing, just the sort of person to paint a Tour champion with the dramatic grandiosity befitting Hannibal himself." -Pat Brady, Editor, Asphalt Magazine At the dawn of the 20th Century, French newspapers used bicycle races as promotions to build readership. Until 1903 these were one-day events. Looking to deliver a coup de grace in a vicious circulation war, Henri Desgrange�editor of the Parisian sports magazine L�Auto�took the suggestion of one of his writers to organize a race that would last several days longer than anything else, like the 6-day races on the track, but on the road. That�s exactly what happened. For almost 3 weeks the riders in the first Tour de France rode over dirt roads and cobblestones in a grand circumnavigation of France. The race was an electrifying success. Held annually (suspended only during the 2 World Wars), the Tour grew longer and more complex with an ever-changing set of rules, as Desgrange kept tinkering with the Tour, looking for the perfect formula for his race. Each year a new cast of riders would assemble to contest what has now become the greatest sporting event in the world.

    Many of today’s jobs require that you be familiar with Microsoft Excel. How can you become proficient at Excel when companies aren’t willing to teach you this valuable skill? This leaves many people trying to learn as they go and never quite feeling 100% comfortable with the program. What’s worse, most people haven’t even scratched the surface of Excel’s potential, even if they’ve been using it for years. If you feel this way, you’re not alone. Think about this for a second; what will your career look like in a year if you don’t take action today and improve your Excel skills? How about five years from now? Unless you take matters into your own hands things may not look much different. According to a recent Wall Street Journal article, people who show proficiency in Microsoft Excel and other common office applications earn, on average, 13% more than those who don’t. For most people this could mean tens of thousands of dollars over just a few years, and this doesn’t even factor in lost promotions and job offers. Can you afford to leave so much on the table as a result of maintaining the status quo? I’ve experienced this transformation in my career and can tell you first hand how it has helped me. When I was fresh out of college and working my first accounting job my manager asked me to complete a project that involved using VLOOKUPS. I enthusiastically obliged, walked back to my desk, and proceeded to panic. I tricked myself into thinking that I was an excel expert only because I knew a few formulas, my limited knowledge only scratched the surface. I turned to a college buddy for help; Google. I eventually managed to learn what I needed, after a lot of time and energy. I’ve climbed the ladder and worn many hats since then. I can’t say that the opportunities I’ve earned in my career are solely due to my increasing Excel proficiency. What I can definitely say is that Excel has earned me more opportunities to prove myself to management than waiting for opportunities to materialize on their own. That’s why I decided to write this book. My goal is to take you from Excel novice to master in the shortest time possible. I wrote my book specifically for the busy professional, in an easy to read manner that gets straight to the point and teaches the meat of Excel. I wrote this book for you. Don’t take my word for it: "I think the writing style is helpful for readers to engage. I like that as I read the book, I felt as if I was in front of someone who was actually teaching me. I also liked the fact that the book is written in a laid back manner. I mean Excel is difficult as it is, why would you want to make it worst by adding some weird terminology to the book? Its plain, simple and easy to follow." -Eliana Pereira, Accountant I have helped many people improve their careers through Excel and now it’s your turn. Here is what you get when you download my book: -18 chapters of the most useful Excel techniques that will immediately take your skills to the next level -Practical use cases plus downloadable workbooks so that you can take what you learn and feel, first hand, how to apply those skills to real world scenarios -A FREE copy of my latest book on Google Sheets so you can stay ahead of the curve You’re at the point of decision.
