Ngokwenene yayiyifowuni esondele kakhulu, kwaye zombini i-Federal Aviation Administration (FAA) kunye neBhodi yeSizwe yoKhuseleko lwezoThutho (NTSB) iyaphanda. Ekugqibeleni, kwathatha umlawuli weenqwelo-moya kunye nabaqhubi bazo zombini ezo nqwelo-moya ukuba baqale esenzweni ukunqanda ukungqubana okunokubulala okuphakathi komoya.
Imizuzu eyoyikisayo esibhakabhakeni phezu kweSikhululo seenqwelomoya saseSan Francisco iqala kamsinya nje emva kokunduluka kwejethi enkulu ye-United Airlines. I-Flight 889 iya eTshayina inabakhweli abangama-268 kunye nabasebenzi. Umqhubi wenqwelomoya uyavuma ukucocwa kwesiqhelo xa kunduluka:
Umqhubi we-United Pilot: “Ilungisiwe ukuba ihambe. United, um, kathathu 889. "
Kodwa njengoko ijethi eManyeneyo inyuka ngeenyawo ze-1,100, umlawuli wesikhululo seenqwelomoya, onxibelelana nomqhubi we-Cessna encinci, uyaqonda ukuba iinqwelomoya zisondele kakhulu kwaye zivaliwe. Uxelela umqhubi weCessna ukuba ahambe emva kwenqwelomoya ye-United.
Umlawuli: "I-7-echo igcina i-zero yahlula ... dlula emva kwenqwelomoya."
UCessna Pilot: "I-7-0 iya kudlula emva kwakhe."
Kwaye uneodolo yabasebenzi baseUnited.
Umlawuli: "889-qalisa ukuya ngasekunene kwakho, gcina ulwahlulo olubonakalayo."
UMichael Barr weNkqubo yoKhuseleko lwe-Aviation kunye noKhuseleko lwe-USC uthe, "Inqwelomoya elula ijikile kwi-United Airline. Leyo yindlela umphathi abona ngayo umzantsi waloo nqwelo-moya, ngoko yayisondele kakhulu.”
Ikufutshane kakhulu, eneneni, iinqwelomoya ziqelelene nje ngeemitha ezingama-300 ngokuthe nkqo kunye neemitha ezingama-1,500 ziqelelene ngokuthe tye. Kwi-cockpit ye-jet ye-United, i-alam yokuphepha ukungqubana iyakhala, ilumkisa abaqhubi beenqwelomoya ukuba behle ukunqanda ingozi esemoyeni. Ibizwa ngokuba sisilumkiso se-TCAS. Abasebenzi be-United, njengoko beyijongile inqwelomoya, ngokucacileyo abonwabanga.
I-United Pilot: "Kulungile, yaqalisa i-TCAS ... yayiyi... kufuneka sithethe."
Umlawuli: "Roger."
Kwaye, eneneni, yayiyi-United Airlines eyacela i-NTSB ukuba iphande esi siganeko. Umnxeba osondeleyo wenzeke ngentsasa yangoMgqibelo, kodwa sisafunda ngako ngeli xesha. Kwaye kweli nqanaba lokuqala, kubonakala ngathi inokuba yimpazamo yomlawuli weenqwelomoya ezibeke ezi nqwelomoya kufutshane kakhulu.
