According to the 9-1-1 recording played during the trial of Zacarias Moussaoui , at 9:17 a.m. , on September 11 , 2001 , when the south tower of the World Trade Center was hit by United Airlines Flight 175 , she and another five people were trapped on the 83rd floor where IQ Financial Systems was located when she called 911 . During the call , the operator tries to keep Doi calm and extract information from her . She answered , '' " Well , there 's no one here yet , and the floor 's completely engulfed . We 're on the floor and we ca n't breathe , And it 's very , very , very hot " '' . Due to privacy reasons , only the first 4 minutes of the dispatch call , which lasted 24 minutes , was released by the courts along with the rest of the recordings , numbering more than 1,600 . As the south tower burned , she asked the operator , '' " Can you stay on the line with me , please ? I feel like I 'm dying . " '' Near the end of the call , Doi spells out the last name of her mother and asks the dispatcher to set up a three-way call so that she can speak to her mother one last time . '' " We could n't put her on , " '' the dispatcher says . '' " We do n't have a three-way system for that . " '' As smoke and heat began to overcome her , Doi gave the 911 operator her mother 's name and phone number in hopes of passing on a last message . That evening , Alderete received a call from the 911 operator who had spoken with Doi while she was trapped in the stairwell , who said she had a message for Alderete from her daughter : '' " Tell my mother that I love her and that she 's the best mom in the whole world . " '' After 24 1/2 minutes , the call cuts off . It took three years for her remains to be found in the rubble . At the National 9/11 Memorial , Doi is memorialized at the South Pool , on Panel S-46
