Famous for leading the Doolittle (or Tokyo) Raid, America's first strike against Japan in World War II, Jimmy Doolittle led a remarkable life as an American pilot. This firsthand account by his granddaughter Jonna Doolittle Hoppes reveals an extraordinary individual:

- An aviation pioneer who was the first to fly across the United States in less than 24 hours and the first to fly "blind" (using only his plane's instruments).

- A barnstormer well known for aerobatics and a popular racing pilot who won every major air race at least once.

- Recipient of both the Congressional Medal of Honor and Presidential Medal of Freedom.

- A four-star general and commander of both the 8th, 12th, and 15th Air Forces.

- A scientist with a doctorate in aeronautical engineering from MIT.

Calculated Risk provides insights into the public and private world of Jimmy Doolittle and his family, and sheds light on the drives and motivation of one of America's most influential and ambitious aviators.

This updated edition contains a new foreword written by Richard P. Hallion, a new afterword written by Clarence E. "Bud" Anderson, and a new introduction by author Jonna Doolittle Hoppes.
