Accident investigations are almost synonymous with the National Transportation Safety Board, or the NTSB. Recognized around the world as the gold standard in investigations, the NTSB's diligence and authority have contributed to findings, probable causes, and recommendations that have improved flight safety for all of us. But what happens if an NTSB investigation doesn't go far enough- or if it misses key information that alter a crash's true legacy? In this layover episode of Take to the Sky: the Air Disaster Podcast, Shelly and Stephanie discuss the documentary Invisible Sky, the story of pilot Georgina Joshi, and the lingering questions her legacy still asks to this day.
