This book is mostly a combat diary, sticking to the day to day events within the author's direct experience. Unlike some diarists, he recreates the feeling of living in the thoughts and experiences of a line combat officer without extended retrospectives on strategy. The prose reveals the author's personality. It is direct without being pedestrian, professional without being obscure, and insightful without editorializing. Pilots will find it interesting as Hathorn fluidly describes sequences of the control inputs as he is manuevering the Cessna O-2 under fire on Forward Air Control missions over Laos. His description of the need to "fly like a drunk" makes sense in the context of the mission.
For those interested in the clandestine nature of the war in Laos, Hathorn's book valuably expands several areas including Igloo White/Muscle Shoals, Prarie Fire and Heavy Hook. While no single comprehensive book has yet been written for this theatre and time, Hathorn gives a great account of the air element that had to coordinate the timing and accuracy of combat air missions and should be part of any library of the Southeast Asia War.
I should add that I was at NKP for 18 months from 1968-1969 with the 56th ACW/SOW and Task Force Alpha. I flew more than 25 missions as a photographer, many with the author's unit, the 23rd TASS. I found few factual recollections that were different from my own.
