Shortly after returning to the Black and Blue Tour , the group faced a harrowing loss with the occurrence of the September 11 , 2001 Terrorist Attacks . On the night of September 10 , the band had completed a sold-out show in Boston , Massachusetts and the following morning Littrell 's wife Leighanne had planned on catching a flight back to Los Angeles aboard American Airlines Flight 11 , along with set carpenter Daniel Lee , who was returning home to Los Angeles to see his wife , who was due to give birth to their second child . That night , however , Leighanne cancelled her flight after deciding to spend more time with her husband . Tragically , Lee was among 92 people killed when the hijacked plane was crashed into the North Tower of the World Trade Center . The next day , during a concert on the next leg of their tour in Toronto , Littrell gave a brief speech on Lee and led the audience in a brief moment of silence for Lee and all the victims of the attacks
