This photo shows a group of 6th-grade students, their teachers, and two National Geographic employees moments before boarding American Airlines Flight 77 on September 11, 2001. None of them survived. The flight was h!jacked and later crashed into the Pentagon, taking the lives of everyone on board. The picture remains one of the most heartbreaking images tied to that day — smiles captured right before unimaginable tragedy. @scarydoze — the most innocent photos can hide the darkest endings. | We
