Teachers and parents at the Children's Discovery Center, the little-known children’s nursery inside the World Trade Center complex - relive what they saw, heard and experienced on September 11, 2001. From the first impact and the confusion that followed to the moment they realized America was under attack, these are their powerful firsthand memories of 9/11 - including the split-second but critical decision made by the nursery teachers, that helped save the lives of all 28 young children and babies in their care. #September11 #911History #WorldTradeCenter #TwinTowers #ChildrensDiscoveryCenter
