Lawmakers in North Carolina are calling on the state’s attorney general to investigate the charter plane company Aero Contractors. The North Carolina-based firm has provided Gulfstream jets to the CIA for use in its secretive extraordinary rendition program. Aero Contractors was founded by a CIA officer who once flew planes for the CIA’s Air America fleet. The American Civil Liberties Union sued Aero Contractors last year for transporting the German citizen Khalid El-Masri after he was seized by U.S. agents in Macedonia.
