The black box is orange—and there are actually two of them. They house the cockpit voice recorder and the flight data recorder, instruments vital to airplane crash analyses. But accident investigators cannot rely on the black boxes alone. Beginning with the 1931 Fokker F-10A crash that killed legendary football coach Knute Rockne, this fascinating book provides a behind-the-scenes look at plane wreck investigations. Professor George Bibel shows how forensic experts, scientists, and engineers analyze factors like impact, debris, loading, fire patterns, metallurgy, fracture, crash testing, and human tolerances to determine why planes fall from the sky—and how the information gleaned from accident reconstruction is incorporated into aircraft design and operation to keep commercial aviation as safe as possible.

Hashtag or trademark, personal or collective expression, #BlackGirlMagic is an articulation of the resolve of Black women and girls to triumph in the face of structural oppressions. The online life of #BlackGirlMagic insists on the visibility of Black women and girls as aspirational figures. But while the notion of Black girl magic spreads in cyberspace, the question remains: how is Black girl magic experienced offline? The essays in this volume move us beyond social media. They offer critical analyses and representations of the multiplicities of Black femmes’, girls’, and women’s lived experiences. Together the chapters demonstrate how Black girl magic is embodied by four elements enacted both on- and offline: building community, challenging dehumanizing representations, increasing visibility, and offering restorative justice for violence. Black Girl Magic Beyond the Hashtag shows how Black girls and women foster community, counter invisibility, engage in restorative acts, and create spaces for freedom. Intersectional and interdisciplinary, the contributions in this volume bridge generations and collectively push the boundaries of Black feminist thought.

Every day, corporations are connecting the dots about our personal behavior—silently scrutinizing clues left behind by our work habits and Internet use. The data compiled and portraits created are incredibly detailed, to the point of being invasive. But who connects the dots about what firms are doing with this information? The Black Box Society argues that we all need to be able to do so—and to set limits on how big data affects our lives. Hidden algorithms can make (or ruin) reputations, decide the destiny of entrepreneurs, or even devastate an entire economy. Shrouded in secrecy and complexity, decisions at major Silicon Valley and Wall Street firms were long assumed to be neutral and technical. But leaks, whistleblowers, and legal disputes have shed new light on automated judgment. Self-serving and reckless behavior is surprisingly common, and easy to hide in code protected by legal and real secrecy. Even after billions of dollars of fines have been levied, underfunded regulators may have only scratched the surface of this troubling behavior. Frank Pasquale exposes how powerful interests abuse secrecy for profit and explains ways to rein them in. Demanding transparency is only the first step. An intelligible society would assure that key decisions of its most important firms are fair, nondiscriminatory, and open to criticism. Silicon Valley and Wall Street need to accept as much accountability as they impose on others.
