“She was trying to protect children,” she said.
“She died, and they lived.”
Bickley believes there are many people who should be recognised for their courage on that day, but agreed Nansi was a hero.
“I think Nansi went way, way beyond what she needed to do,” she said.
“She could have saved her own life. She cared more for the children.”
Nansi’s godson, Dai Powell, campaigned for greater recognition and said stories of what happened were passed down through his family for decades.
“My ultimate hero. No-one will ever touch her,” he said.
“We’d all like to think we’d do the same thing, but until it happens we don’t really know.
“Her heroism is just unbelievable.”
