Review of United States Assistance to Peruvian Counter-Drug Air Interdiction Efforts and the Shootdown of a Civilian Aircraft: Report of the Select Committee on Intelligence, United States Senate [open pdf - 3MB]
This document recommends: "The legal requirement for a Presidential Determination prior to providing U.S. assistance to a foreign government engaged in a program of interdicting drug trafficking planes should be changed to an annual Presidential Certification process with more thorough reporting requirements. Also, U.S. support to the Peruvian counter-drug air interdiction program should not be resumed unless and until the President has made a Certification as described in Recommendation I, and the U.S. and Peruvian Governments have addressed the specific shortcomings highlighted by the April 20 tragedy and subsequent reviews. On the morning of April 20, 2001, a Peruvian Air Force A-37 fighter engaged in counter-drug operations over northeastern Peru fired on and disabled a suspected drug trafficking aircraft. The single engine float plane actually was owned and operated by the Association of Baptists for World Evangelism and was carrying missionaries returning to their homes in Iquitos, Peru. One of the missionaries, Veronica Bowers, and her infant daughter Charity were killed by the gunfire."
