After Iran shot down an American F-15 fighter jet on Friday, one airman was rescued, but the other remains missing.  We have the latest on the efforts from both Iran and the U.S to try and locate the crew member, where the crash site was located, and how each airman is taught and trained how to survive situations just like this one.   While there is a reward for the missing American, Iranian officials are urging civilians to capture the airman “alive.”
