Aviation historian Alfred Price, author of Sky Battles and Sky Warriors among many other noted books, has once again roamed wartime skies from 1911 to 1999 to tell the stories of 22 air actions, all very different, that together show how the air weapon has evolved in those 9 decades. From the operations of the Italian air expeditionary force in Libya in 1911-12, to the shooting down in less than two minutes of two Yugoslav MiG fighters in 1999, this is an all-action history of the increasing power and versatility of air arms over the years.
