Former White House correspondent aboard Air Force One on 9/11 reflects on journey 20 years later

Former President George W. Bush spent nine hours in the sky aboard Air Force One on 9/11 over fears it was unsafe to return to the White House. Ann Compton, a former White House correspondent for ABC News, was one of the few reporters also on board Air Force One that day. She joins CBSN's Lana Zak to describe what that day was like, 45,000 feet in the air.
