Rhoqo kuthathelwa ingqalelo njengoKumkanikazi esibhakabhakeni, iBoeing 747 ikwanaso isithsaba njengeyona nqwelo moya ikhawulezayo yabakhweli- kunye nenkonzo yakhe njengoMkhosi woMoya umenza abe zezona moya zinamandla ekusebenzeni.

Unokuthenga ngetyala inani le-747 & apos; saso sonke isantya: i-hump eyahlukileyo kwi-fuselage yakhe yenza ukurhuqa okuncinci kwaye ivumela i-747-400 ukuba ihambe kamnandi ngesantya seMak .84, okanye iipesenti ezingama-84 isantya sesandi. (Ngokwembono ethile, umndilili wenqwelomoya uhamba ngesantya esijikeleze iMach .82.) Imodeli entsha ye-747-8 yokuhamba ngenqanawa eMach .855.

Kodwa zombini iinqwelomoya ziye zavavanywa ukuya kumda wazo kwaye zasondela kuMach 1. 747s ziqinisekiswe ngokusesikweni yi-FAA ngesantya ukuya kuthi ga Mat. 92 , kunye no-747-8 kuvavanywe ukuya kuthi ga kwiMak .98 .

I-747 ayisiyo & apos; ayikhawulezi nje. Ikwathatha ikhredithi ngokwenza namhlanje Indlela yokuphila ebhabha kakhulu enokwenzeka . Yayiyinqwelomoya yokuqala eyayinokuhlalisa abakhweli ngokwaneleyo Iinqwelomoya ezihamba umgama omde ezifikelelekayo . Ngaphambi kokuba iPan Am 747 yokuqala ihambe, ukubhabha yayililungelo eligcinelwe abambalwa abakhethiweyo abanezipaji ezingqindilili.

Ukwaphethe irekhodi yeeyunithi ezininzi ezithengiselwe nayiphi na imodeli yenqwelomoya kwimbali. ILufthansa ithathe ukuhanjiswa kwe-1,500th 747 ngo-2014 umzekelo 747-8.

Emva kweminyaka engaphezulu kwama-40 kwindawo ephezulu yeenqwelo-moya ezinde, iJumbo Jet ethandwayo ithathelwa indawo yenye inqwelo-moya entsha, elula, nenamandla ngakumbi. Ezi azinakuhamba ngokukhawuleza okukhulu, kodwa zisebenzisa ipetroli ngokufanelekileyo, zibeka emngciphekweni izihlalo ezingenanto, kwaye ngokubanzi zenze umsebenzi wenziwe.

Kodwa ngaphandle kokutshintsha kweemeko zentengiso, i-747 ifumene indawo ekhethekileyo ezintliziyweni zabakhweli kunye neenqwelo moya ngokufanayo. Ayibanga sigqibo silula kubathwali bokushiya uKumkanikazi ngasemva.

Ndacinga ukuba yinqwelomoya entle kakhulu. Akukho luthelekiso, igosa eliyintloko le-ANA, u-Osamu Shinobe, uxelele ii-Smithsonian & apos; s Iphephancwadi lomoya kunye nendawo Ngo-2014 wenqwelomoya & isigqibo sokuyeka inkonzo ezingama-747. Ndiziva ndibuhlungu kakhulu xa ndibona umhlala phantsi.

Nangona kunjalo, ezinye iinqwelo-moya zihlala zinyanisekile ebukhosini. I-British Airways, ephethe ihlabathi kunye neenqwelo-moya ezinkulu ze-747s, akanazicwangciso zokuthatha umhlala phantsi kwinqwelomoya . Kwaye ezinye iinqwelomoya zijikeleze umhlaba zinkulu ngokwaneleyo iinqanawa ezingama-747 ukuba awuyi kuphumelela kwaye ungcinezelwa (okwangoku) ukufumana inqwelomoya kwi-747.

Kwaye iJumbo isenomsebenzi obalulekileyo ophambi kwayo. Usebenza ngokonwaba kukaMongameli. Zombini iindiza ezikhoyo zoMkhosi woMoya zingama-747, kwaye isibini samawele soMkhosi woMoya siya kuphuculwa sibe yimodeli ezintsha ezingama-747-8.

Kwakukho ukungxola apho i-747-8 yayiza 'kugxothwa' xa uDonald Trump eyichasile le nkqubo kunye neendleko ezikhulayo. Ucel'umngeni ku-Boeing ukuba enze okuthile ukunciphisa iindleko, kodwa amandla ancomekayo okubhabha I-White House yenza ukuba kube nzima .

Emva kokukhwela okokuqala namhlanje kwi-Air Force One, nangona kunjalo, uTrump ubonakala efudumele kuKumkanikazi. 'Yintoni enokubonakala intle kangaka xa unama-30?' Ubuze .
