Here is an excerpt from an article by Patricia Phillips on Examiner.com about Culbertson's experience of 9/11:
"It's difficult to describe how it feels to be the only American completely off the planet at a time such as this," Culbertson told ground controllers. As the tragedy unfolded, Culbertson learned that a friend of his had been flying Flight 93 when its heroic crew and passengers forced its early crash in Pennsylvania, diverting it from another attack in Washington, D.C. Flight 77 crashed into the Pentagon.Please take a moment today to remember those crew members and passengers who perished on board the four hijacked planes, and all those who died on the ground as a result of the terrorist attacks on September 11, 2001.
Culbertson spoke poignantly of exhaustion and a sense of isolation. He kept reporting their observations, including a "haze" over Washington, D.C., and the "odd bloom" of the smoke rising from the Twin Towers.
