This is a great book, written with true insight and enthusiasm for the subject.Recommended for anyone interested in World War 1 or aviation history.

This is the finest and easiest to read history of aviation in the "war to end all wars" that I have ever encountered. I first read this book 40 years ago in high school, and wore out my first paperback copy (once I could afford to buy one). Even after a career in the Air Force, I still find it relevant, and encouraged my junior officers to read my second copy, until it wore out. It took me until 1988 to find a hardback copy, which sits in a place of honor in my library right next to my 3rd paperback copy. Quentin Reynolds did his homework, researching combat aviation from medeival concepts right up the end of the War and beyond. By the end of the book, you know as much about the aircraft, the pilots, and the tactics as you would if you had flown wingman for a WWI ace. Fun to read, excellent composition, a true work of the writer's art.

The Federal Bureau of Investigation (FBI) is a group of scientific police. There are about 6,000 members total, and this book is about the history of the FBI.
The founder, J. (John) Edgar Hoover, was a lawyer. In 1921 his employer, a police officer, asked him to start a group of "scientific police".
Men wanting to apply for a job working for the FBI had to go through very tough tests. For months they would train in finger-printing, riflery, and many seemingly unimportant tasks such as how to tell human blood from animal blood. These would be very useful later on.
The Federal Bureau of Investigation, or FBI, as we know it today, was established in 1924 and is still serving us well.
