U fiirso qoraalka hoose ka dibna ka jawaab su'aasha kadib isla luqadda qoraalka:  Mohamed Atta, oo ah hogaamiyaha weerarada, iyo nin kale oo afduubayaal ah, Abdulaziz al-Omari, ayaa yimid garoonka diyaaradaha ee Portland 05:41 Eastern Daylight Time September 11, 2001. Waxay raaceen diyaaradii Colgan Air Flight 5930, taasoo la qorsheeyay in ay ka duusho Portland, Maine, 06:00 subaxnimo, una duusho Boston. Labadaba afduubayaashu waxay lahaayeen tigidhada fasalka koowaad oo leh duulimaad isku xiraya Los Angeles; Atta wuxuu hubiyay laba shandadood, Omari midna. Markii ay soo galeen, Nidaamka Xisaabinta Rakaabka ee Kumbuyuutarka (CAPPS) wuxuu u doortay Atta baaritaan dheeraad ah oo ku saabsan shandadaha, laakiin wuxuu fuulay iyada oo aan wax dhibaato ah dhicin. Duulimaadkii Portland wuxuu ka soo baxay waqtigii loogu talagalay wuxuuna yimid Boston 06:45. Saddex qof oo kale oo afduubayaal ah, Waleed al-Shehri, Wail al-Shehri, iyo Satam al-Suqami, ayaa yimid garoonka diyaaradaha Logan 06:45, iyagoo ka tagay baabuurkooda kirada ee garoonka diyaaradaha. 06:52, Marwan al-Shehhi, duuliyihii afduubka United Airlines Flight 175, ayaa ka soo wacay taleefanka dadweynaha ee garoonka diyaaradaha ee Logan ilaa taleefanka gacanta ee Atta. Maadaama aan la siin kaararka duulimaadka ee duulimaadka 11 ee Portland, Atta iyo Omari ayaa la baaray oo ay ka gudbeen amniga Boston. Markii si deg deg ah loo baaray ka dib duulimaadkii ka yimid Portland, saraakiisha diyaaradda ma aysan saarin boorsooyinka Atta duulimaadka 11. Suqami, Wail al-Shehri, iyo Waleed al-Shehri ayaa iyaguna iska diiwaangeliyey duulimaadkii Boston. Wail al-Shehri iyo Suqami mid kastaa wuxuu hubiyay hal boorso; Waleed al-Shehri ma hubin wax boorso ah. CAPPS waxay u dooratay dhamaan sadexda si ay u baarto baagagga. Maadaama baaritaanka CAPPS uu ahaa kaliya boorsooyinka, seddexda afduubayaasha ma aysan soo marin baaritaan dheeri ah barta baaritaanka amniga rakaabka.  Su'aal: yaa iska indho tiray boorsooyinka?
Waleed al-Shehri
