"Guttman describes the group’s operations from its arrival in Europe to its demobilization in 1919 and includes accounts from more recent reunions. Readers interested in the history of the U.S. Army Air Service will find rich detail about a unit that remains in service with the U.S. Air Force as the 1st Operations Group, still inspired by its old motto, Aut Vincere Aut Mori ("Conquer or Die")." -Thomas Zacharis, Military History (May 2009)
"Author Jon Guttman takes us through the faltering starts and later the more intense battles against some of the best that the German Fliegerkorps had to offer. Chock full of superb period photos of both the men and their machines, this is further enhanced by the quality profiles of artist Harry Demspsey, who specializes in WWI fighter aircraft. This all equates to the best book on the subject that I have read. A riveting account of the early days of US aerial combat and a book that I can most highly recommend to you."- Scott Van Aken, modelingmadness.com (June 2008).
