Tuesday, Sep. 11, 2001, dawned cool and clear, with sunny skies all along the eastern seaboard. For Air Force aviators like Lt. Col. Timothy "Duff" Duffy of the 102d Fighter Wing at Otis Air National Guard Base, Massachusetts, the day held the promise of perfect flying weather, at a time when the U.S. civil aviation system was enjoying a period of relative peace, despite concerns about a growing terrorist threat. More than ten years had passed since the last hijacking or bombing of a U.S. air carrier. That morning, however, the country came under a shocking, coordinated aerial assault by nineteen al Qaeda hijackers...The attack plan carried out by the suicide operatives had been years in the making. It was intended to cause mass, indiscriminate casualties and to destroy or damage the nation’s financial, military, and political centers, four high value U.S. targets selected by bin Laden, independent operator Khalid Sheikh Mohammed, and al Qaeda operations chief Mohammed Atef... By the time 1 World Trade Center, North Tower, collapsed at 10:28 a.m. EDT, almost three thousand people had been killed or were dying; the financial center of the U.S. had been reduced to burning, toxic rubble; the iconic symbol of the military strength of the country had been severely damaged; the tranquility of a field in Pennsylvania had been shattered; U.S. Air Force and Air National Guard fighter aircraft had set up combat air patrols over Washington, D.C., and New York City; and the administration of President George W. Bush and the Department of Defense (DOD) had begun shifting major resources of the federal government and military services to a new national priority, homeland defense.

“A maddening, essential study in misinformation, jingoism, bad intelligence, and other hallmarks of the recent American past.”—Kirkus (starred review) Anyone who experienced the attacks on September 11 cannot forget the imagery: the smoking, falling towers, the Pentagon smoldering, the Shanksville crash site, the first responders. But there is an invisible story hidden in the wreckage, one that required years of patient investigation and the piecing together of a sequence from many scattered sources. By establishing the most definitive timeline of how that day unfolded, William M. Arkin shows how the US government failed in the face of the unprecedented attack. It is a story of laughable airport security, vulnerable airspace, blind intelligence, poor communications, muddled orders, Pentagon chaos, and presidential isolation. Everything about the emergency procedures of the governments—from White House security to continuity of government to military alerts—went wrong. On That Day is a stunning, nightmare journey through a government reeling in confusion while many civilians performed individual acts of heroism. It is a chilling exposé of government negligence and overreach, and a constitution in crisis.

On September 11, 2001, the North American Aerospace Defense Command, based at Peterson Air Force Base, Colorado, under the command of Gen. Ralph E. Eberhart, oversaw three air defense regions, which were responsible for protecting the airspace over Alaska, Canada, and the continental United States. The last of these, the Continental United States NORAD Region (CONR), under the command of the dual-hatted commander of First Air Force, Maj. Gen. Larry K. Arnold, oversaw the Northeast, the Western, and the Southeast Air Defense Sectors. The locations of the departures, flight paths, and crash sites of the four aircraft hijacked on September 11, 2001, were all in the Northeast Air Defense Sector, commanded by Col. Robert K. Marr (see Diagram, NORAD Air Defense Structure on 9/11, p 53). On September 11, 2001, the responsibility for defending continental U.S. airspace rested with only fourteen fighter aircraft at seven air defense alert sites across the country. Based in Rome, New York, the Northeast Air Defense Sector had only two alert sites on which to call-Otis Air National Guard Base in Cape Cod, Massachusetts, and Langley Air Force Base in Hampton, Virginia. Each site had two designated alert fighters on duty twenty-four hours a day, seven days a week. Many other fighter aircraft were based across the country, but they were not NORAD assets, and it would take time to arm them and organize their crews.

The influence of science fiction writer H. P. Lovecraft is widely felt in modern literature; authors from Robert E. Howard to Stephen King can claim him as their ancestor. But cinema too has seen Lovecraft's impact, and author Charles Mitchell offers here a comprehensive guide to the dozens of films that are representative of this influence. Mitchell studies the films in detail, analyzing the major Lovecraft elements and examining the fidelity of the films to the original works. Amateur films as well as television productions and foreign cinema, are included in Mitchell's scrutiny, revealing the challenge of transcribing Lovecraft to the screen, while at the same time suggesting the potential of Lovecraft's work for future, quality screen adaptations. In addition to plot summaries, entries for each film include annotated cast lists, critiques of actors' performances, the degree of fidelity to Lovecraft, and representative quotes from each film. This thorough work will be of interest to students of cinema as well as modern literature.

This illustrated, large-format book presents the U.S. Air Force Art Program's depiction of the Air Force across the service's history, starting with the birth of U.S. military aviation under the auspices of the Army. It interweaves the story of the Art Program, including features on artists and their thoughts on significant works, with the history of the birth and growth of the Air Force itself. The volume includes a foreword by Gen. Mark A. Welsh III, the current Air Force Chief of Staff, who calls the book a "celebration" that records "how the connection between Airmen and artists began, how this relationship evolved, and how artists have documented Air Force operations over the decades." This publication would make a great coffee table book. The author, Dr. Timothy R. Keck, spent his career in the Air Force History program and championed the Air Force Art Program while serving as command historian of Pacific Air Forces. He retired as the Air Force senior historian in 2012. This historic art reference work may appeaal to current airmen, veterans, and members of the general public with an interest in the history of air power, particularly as it is portrayed in Air Force. Additionally, art students and libraries with art history and military collections may also be interested in this work.

Innumerable books have been published on the two most famous fighter aircraft of all time, the Supermarine Spitfire and the Messerschmitt Bf109. But books setting out to tell the story of both aircraft are very much rarer - probably fewer than the fingers of one hand. Yet their joint story is one which bears retelling since both were essential to the air campaigns of World War Two. Incredibly, the men who designed them lacked any experience of designing a modern fighter. R J Mitchell had begun his career working on industrial steam locomotives, Willy Messerschmitt had cut his aeronautical teeth on light and fragile gliders and sporting planes. Yet both men not only managed to devise aircraft which could hold their own in a world where other designs went from state-of-the-art to obsolete in a staggeringly short time, but their fighters remained competitive over six years of front-line combat. Despite the different ways their creators approached their daunting tasks and the obstacles each faced in acceptance by the services for which they were designed, they proved to be so closely matched that neither side gained a decisive advantage in a titanic struggle. Had either of them not matched up to its opponent so well, then the air war would have been a one-sided catastrophe ending in a quick defeat for the Allies or the Axis powers, and the course of twentieth century history would have been changed beyond recognition.

Statistical Inference via Data Science: A ModernDive into R and the Tidyverse provides a pathway for learning about statistical inference using data science tools widely used in industry, academia, and government. It introduces the tidyverse suite of R packages, including the ggplot2 package for data visualization, and the dplyr package for data wrangling. After equipping readers with just enough of these data science tools to perform effective exploratory data analyses, the book covers traditional introductory statistics topics like confidence intervals, hypothesis testing, and multiple regression modeling, while focusing on visualization throughout. Features: ● Assumes minimal prerequisites, notably, no prior calculus nor coding experience ● Motivates theory using real-world data, including all domestic flights leaving New York City in 2013, the Gapminder project, and the data journalism website, FiveThirtyEight.com ● Centers on simulation-based approaches to statistical inference rather than mathematical formulas ● Uses the infer package for "tidy" and transparent statistical inference to construct confidence intervals and conduct hypothesis tests via the bootstrap and permutation methods ● Provides all code and output embedded directly in the text; also available in the online version at moderndive.com This book is intended for individuals who would like to simultaneously start developing their data science toolbox and start learning about the inferential and modeling tools used in much of modern-day research. The book can be used in methods and data science courses and first courses in statistics, at both the undergraduate and graduate levels.
