It was a heartening moment captured amid overwhelming bleakness: a 3-year-old Hurricane Katrina survivor wrapping her chubby little arms round the air force pararescue jumper who had rappelled into New Orleans to save the girl's family from floodwaters.
The 2005 photograph showing a toddler with pigtails and an ear-to-ear grin holding tight to Staff Sergeant Michael Maroney was soon everywhere - plastered on Burger King placemats, AT&T phone cards, a magazine cover.
For many people, including Maroney, the photo represented hope at a time of total devastation.
"It had been such a rough week; when she wrapped me up in that hug, I was in la-la land," Maroney, now 40, told the Washington Post. "Nothing else existed. I was just loving that hug."
Maroney never got the child's name, and he has never stopped trying to find her.
