On 5 October 1986, the Corporate Air Services C-123, carrying Eugene Hasenfus was shot down over Nicaragua, which killed two US pilots, William H. Cooper and Wallace B. Sawyer Jr., and one Latin American crewmember. "Rodriguez unsuccessfully attempted to call Gregg to inform him of the missing plane. He reached Watson, who in turn notified the White House Situation Room. The following day, Rodriguez called Watson again and told him that the airplane was one of North's." Hasenfus told reporters that he worked for "Max Gomez," an alias for Rodríguez, and "Ramon Medina," an alias for Luis Posada Carriles, of the CIA. On 10 October 1986, Clair George, the head of CIA clandestine operations, testified before Congress that he did not know of any direct connection between Hasenfus and Reagan administration officials. In the fall of 1992, George was convicted on two charges of false statements and perjury before Congress but was pardoned on Christmas Eve that year by President Bush.
