Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: 747 yakagadzirwa apo kufamba nendege kwakanga kuchiwedzera muma1960. Nguva yokufambisa nendege dzezvokutengeserana, yakatungamirirwa nokuzivikanwa kukuru kweBoeing 707 neDouglas DC-8, yakanga yachinja zvikuru kufamba nzendo refu. Kunyange isati yarasikirwa nechibvumirano cheCX-HLS, Boeing yakakumbirwa naJuan Trippe, purezidhendi wePan American World Airways (Pan Am), mumwe wevatengi vavo vanokosha zvikurusa vendege, kuvaka ndege inotakura vanhu yakapetwa kaviri kukura kwe707. Munguva iyi, airport congestion, kwakawedzera nokuwedzera kwenhamba vatakurwi akatakurwa pamusoro munenge duku ndege, akava dambudziko kuti Trippe akafunga aigona kugadziriswa ne ndege itsva yakakura.In 1965, Joe Sutter akatamisirwa kubva Boeing kuti 737 kukura chikwata kutarisira magadzirirwo zvidzidzo kuti itsva airliner, kare akapiwa womuenzaniso nhamba 747. Sutter akatanga chidzidzo chokugadzira nePan Am nedzimwe ndege, kuti anzwisise zviri nani zvavaida. Panguva iyoyo, vanhu vakawanda vaifunga kuti 747 yaizotsiviwa nendege dzinotakura vanhu dzinobhururuka kupfuura inzwi. Boeing akapindura nokugadzira 747 kuitira kuti igone kuchinjwa nyore nyore kuti itakure zvinhu uye kuti irambe ichigadzirwa kunyange kutengeswa kworudzi rwomutakurwi kwakaderera. Muchikamu chevatakuri, kudiwa kuri pachena kwaive kwekutsigira nzira dzekutakura dzakatumirwa mumidziyo dzaive dzichiunzwa zvakanyanya panguva imwecheteyo. Midziyo yekutumira yakajairika ine 8 ft (2.4 m) square kumberi (yakakwira zvishoma nekuda kwenzvimbo dzekusungira) uye inowanikwa mumakumi maviri nemakumi mana emamita (6.1 uye 12 m) marefu. Izvi zvaireva kuti zvaizova zvinobvira kutsigira 2 paupamhi 2 yakakwirira murwi mumidziyo maviri kana matatu mitsara yakadzika ane fuselage saizi yakafanana yapfuura CX-HLS chirongwa.  Mubvunzo: Ndeapi ndege mbiri dzakakurumbira dzakachinja kufamba nzendo refu?
