The Korean War Air Combat Glossary includes military terms, slang and definitions used by the Korean War veterans to whom Truckbusters From Dogpatch is dedicated.
To help establish additional military and air force history resources about the so-called "Forgotten War," the Glossary also includes biographical information, Korean War stories and photographs of many leaders of the 18th Fighter-Wing, Fifth Air Force and other senior military leaders whose decisions affected the missions and operations of the 18th Wing, 18th Fighter-Bomber Group and the Wing's associated squadrons. The Glossary includes many photographs and video of 18th Fighter-Bomber Wing Korean War air combat operations when they were flying the P-51 Mustang and the F-86 Sabrejet aircraft.
The list includes the names and where known, biographical information about those pilots and Airmen who lost their lives during 37 months of Korean War combat. The information is far from complete and will certainly be expanded through the efforts of the 18th Fighter Bomber Wing Association and others.
The names of Two Squadron, South African Air Force (SAAF) fliers are also included.
Information on American pilots is drawn from the files of the 18th Fighter-Bomber Wing Association, family records and recollections, and, where possible, from unit history reports. Sadly, even the unit histories were often incomplete or hasty in recording the status or circumstances of a pilot and his loss to the unit. When the unit history does mention the pilot, however briefly, that notation is included.
