As a fifth grader, former commander of the NASA Extreme Environment Mission Operations (NEEMO) Dorothy Metcalf-Lindenburger said she was looking forward to watching the Challenger launch because her parents were teachers. "And what we saw was not what we expected to see," she said Wednesday on "Fox & Friends." Fox Nation's "73 Seconds to Disaster" examines the fateful decisions that led to this tragedy and honors the seven true American heroes onboard the Challenger. "I appreciate so much that the Challenger Centers, that I work with now as a board member, are helping pave the way," she said. "We have students that walk through the door that will be flight controllers and teachers leading in this mission."
