Air Fore Lt. Col. Michael Hostage, 35, was interviewed in a Defense Department pool broadcast shown on American television. Hostage, an F-15 pilot, escorted bombers in making runs over Iraq.

"It was so wonderful to know he's back from this mission," she said. "We're still concerned. This is definitely not over. We realize there are still Iraqi planes out there that are going to come, and when they do he's the one who's going to have to get them."
