Resilience HQ on Instagram: "A rare piece of footage captures the exact moment the first plane struck the World Trade Center on September 11, 2001. It was filmed by French brothers Jules and Gédéon Naudet, who were in New York documenting the daily lives of FDNY firefighters from Engine 7, Ladder 1. What began as a routine call to check a suspected gas leak turned into one of the most historic and haunting recordings of modern times. #resiliencehq #history #911"
