Although the race took place during peacetime, Lancaster is in solid military-history territory as he recounts Mitchell’s background and discusses aviation success during WWI and the plan to use the race to prove that airplanes would be essential to the military of the future. The race itself was fraught with peril, and the author recounts in great detail the inherent struggles of trying to fly cross-country when there were no navigational aids, and the weather could prove deadly. In the end, there were numerous crashes, injuries, and fatalities, and Lancaster covers all of it, making for thrilling reading. The book also includes outstanding photographs. An excellent read for those interested in aviation, the military, and American history..
