“We've needed a book like this for years, and this one delivers. Đồng Sỹ Hưng, an accomplished MiG pilot, gives us a fresh, challenging take on air combat from the North Vietnamese perspective. Bringing new Vietnamese and Russian sources to English readers for the first time, this work is sure to provoke discussion, but it’s a must-read for anyone studying the Vietnam War.”—Michael W. Hankins, curator, Smithsonian National Air and Space Museum, and author of Flying Camelot

“Đồng Sỹ Hưng presents a thoughtful and authoritative analysis of airpower in the Vietnam War from a North Vietnamese perspective. This unique study from “the other side of the hill,” which combines technological sophistication with an understanding of the strategic context, adds new insight into the conduct of the Vietnam War and its downstream effects on contemporary air operations. Combat in the Sky is a must-read for anyone interested in the many dimensions of airpower.”—Professor John Andreas Olsen, Colonel, Royal Norwegian Air Force

"At last we have accounts of all the aerial battles over North Vietnam from a Vietnamese perspective. Combat in the Sky is essential reading for those piecing together the clashes between the MiGs and their American adversaries."—Michael E. Weaver, PhD, associate professor, Department of Air Power, Air Command and Staff College
