"The Air Bridge Denial (ABD) Program is an anti-narcotics program operated by the U.S. Central Intelligence Agency in Colombia and Peru. Starting in the 1990s, it targets traffickers transporting illicit drugs through the air by forcing down suspicious aircraft, using lethal force if necessary. The program was suspended in April 2001 when a legitimate civilian aircraft was shot down in Peru and two U.S. citizens were killed. It was restarted in Colombia in August 2003 after additional safeguards were established."@en . .

As of 2005, the United States had provided $68 million for the program, which had so far only produced only one drug seizure. In 2010 the Government Accountability Office produced a report stating that the program faced challenges and that the effectiveness of the program at stopping narcotics trafficking was difficult to assess. It noted, however, that the program often advanced broad foreign policy objectives of the United States."@en . . . . . . . . . . . . . "Air Bridge Denial Program"@en .
