Air Bridge Denial Program
"The Air Bridge Denial Program derives its name from its goal: to deny the South American drug network the “air bridge” used to transfer semi-refined cocaine from growing areas in rural Peru, Bolivia and Colombia to processing plants in Colombia and onward to destination countries. While this transportation network also includes land and water routes, its lifeblood is aerial transportation.4 The denial of this air bridge, initially through the interdiction of suspect planes on the ground and later through the use of weapons against aircraft in flight, is seen as a key component of the overall success of U.S. counter-drug operations. However, while this component has had a long and successful history, it has been controversial."
