The commercial-free special is designed to give children a tailor-made forum for emotions and understanding regarding the tragic events.
Ellerbee said she found there was all kinds of misinformation among kids about 9/11, such as "I heard that there were 500 planes that disappeared in the air."
"The most stunning one was, 'I heard that 9/11 never happened,'" Ellberbee said.
In her 20 years of producing groundbreaking news specials aimed at children, Ellerbee said she has learned not to talk down to children and not to be afraid to be straight with them. She also has a philosophy about addressing tragedy.
"Wherever you see bad stuff happening, you see good people trying to make it better," she said.
