This haunting photo shows a group of 6th graders, teachers, and National Geographic staff just before boarding American Airlines Flight 77 on September 11, 2001. Their flight was later hijacked and crashed into the Pentagon, killing all on board. It’s one of the most devastating stories from 9/11, highlighting how people from every walk of life — including children on a school trip — became victims in a single moment. The image serves as a quiet, powerful reminder of the lives lost that day. | t
