Airplane debris including Flight 77's black boxes,[101] the nose cone, landing gear,[102] an airplane tire,[103] and an intact cockpit seat[104] were observed at the crash site. The remains of passengers from Flight 77 were found at the Pentagon crash site and their identities confirmed by DNA analysis.[105] Many eyewitnesses saw the plane strike the Pentagon. Further, Flight 77 passengers made phone calls reporting that their airplane had been hijacked. For example, passenger Renee May called her mother to tell her that the plane had been hijacked and that the passengers had been herded to the back of the plane. Another passenger named Barbara Olson called her husband (U.S. Solicitor General Theodore Olson) and said that the flight had been hijacked, and that the hijackers had knives and box cutters.[4][95][106]
