The red phone rang one day in December 1955, and Shoup answered it, Pam says. "And then there was a small voice that just asked, 'Is this Santa Claus?' "

His children remember Shoup as straight-laced and disciplined, and he was annoyed and upset by the call and thought it was a joke — but then, Terri says, the little voice started crying.

"And Dad realized that it wasn't a joke," her sister says. "So he talked to him, ho-ho-ho'd and asked if he had been a good boy and, 'May I talk to your mother?' And the mother got on and said, 'You haven't seen the paper yet? There's a phone number to call Santa. It's in the Sears ad.' Dad looked it up, and there it was, his red phone number. And they had children calling one after another, so he put a couple of airmen on the phones to act like Santa Claus."

"It got to be a big joke at the command center. You know, 'The old man's really flipped his lid this time. We're answering Santa calls,' " Terri says.
