\"Stunning . . . Challenger is a remarkable book. It manages to be a whodunit that stretches hundreds of pages, a heart-pounding thriller even though readers already know the ending. The passion and ideals at the heart of human spaceflight come through, which only adds to the tragedy of understanding how many chances there were to save the astronauts aboard. Our faith in the systems that run our world is really faith in our fellow man-a chilling reality to remember.\" -The Atlantic
