On September 11, 2001, United Flight 93 was hijacked by four Al Qaeda terrorists. The passengers and crew fought back and because of that, the plane crashed outside of Shanksville, Pa., instead of its likely target: the U.S. Capitol.

Part of the plane crashed onto land owned by Tim Lambert, a public radio reporter at WITF in Harrisburg, Pennsylvania. The crash would end up connecting Tim, in surprising ways, to the first responders who managed the aftermath and to the families of the people who died on board. He gained access and insight into 9/11 that no other reporter had.

20 years after Flight 93's crash, Lambert and NPR's Scott Detrow tell the story of Flight 93: what happened that day and what happened over the years to come.
