s04e10 The Black Jet

Harm and Mac's original mission is to represent a Navy flier whose Stealth jet is thought to have crashed in Iran due to a mechanical failure. But when the pilot slips Harm a message indicating that the $80 million plane didn't crash and is hidden, the assignment becomes nearly impossible: get the pilot -- and the costly aircraft -- back to the U.S. without letting the Iranians know that the plane is intact.
