On February 20, 1962, as millions of Americans waited anxiously, astronaut John Glenn blasted off in his rocket ship, Friendship 7, and became the first American to orbit the Earth.;Although the risks of such a mission for Friendship 7 were well known, no one including Glenn knew the peril he was about to encounter in space. John Glenn was one of the Mercury 7 astronauts, the early pioneers of manned space flight. His historic flight followed years of intensive physical training and a devotion to a career in the exciting but risk-filled world of aviation.;Ruth Ashby’s dramatic story of John Glenn’s near-disastrous mission in Friendship 7 also takes young readers through his small-town Ohio childhood, his extraordinary experiences as a fighter pilot in two wars, and his life as an astronaut in the prestigious and dangerous Mercury 7 program. The book concludes with Glenn’s successful career as a US senator and his triumphant return to space in 1998 at the age of 77.
