Caribou Airlines is a detailed history of USAF C-7A operations in Vietnam. It is about aircrews, crew chiefs, maintenance officers, line chiefs, phase inspection personnel, maintainers, specialty shop personnel, supply personnel, personal equipment specialists, commanders, staff personnel, etc. They made it possible to deliver troops, rations, guns, ammunition, beer, equipment, animals, soda, etc. to hundreds of bases on the battlefields of Vietnam. The 483rd Tactical Airlift Wing and its units were not an airline, per se. They were tasked with supporting Army and Marine units and other customers with air-landed and air dropped supplies using pre-defined, emergency, and opportune sorties to front line locations where the supplies were needed. The history of the Military Advisory Command, Vietnam (MACV); C-7A Caribou Association newsletters; citations of awards and decorations; and personal stories of those involved provide the context for this book.
