I have a test where I am given the following article, what is an answer for the question: Who is the partner of the man Catherine Foley is working with? ?  Russian company Sukhoi has developed a fifth-generation jet fighter, the Sukhoi Su-XX, nicknamed Sabretooth, flown by test pilot Alexei Kedrov, from a remote Russian airbase. Recently suspected of being a traitor due to his love affair with American ecologist Catherine Foley, Alexei is patriotic and is unaware that Catherine is not who she claims and is working with London-based arms dealer Dick Murdoch. A mystery man also appears to control the effort to steal the Sabretooth. Murdoch and his new partner Aziza, want to steal the Russian jet and employing numerous mercenaries and clandestine agents, puts the entire flight test unit in jeopardy. Worried about his family, pilot Boris Korin helps Murdoch steal Sabretooth.  When Catherine is seen to be falling for Alexei, she is eliminated along with other assassinations and an audacious attack on a former Russian outpost.  Alexei and other pilots in his team have to contend with not only the Russian FSB, but also agents from the CIA and British special services.  When Air Force One on the way to Moscow, is threatened, the McDonnell Douglas F-15 Eagle escorts try to shoot down Sabretooth but Alexei uses the extraordinary capability of his top-secret aircraft to outfly the American attack and bring his aircraft home safely.  Murdoch, however, with help from the mystery man behind the efforts to steal Sabretooth, is still at large.
