Lezi zinto azikwenziwanga ezindizeni zanamuhla zokuhweba
Emashumini eminyaka, amafilimu kanye nethelevishini banikeze imibono eyingozi kakhulu embonini yezokuhweba ezokuhweba, egcwalisa izingqondo zabahambi ngokukhathazeka ngaphambi kokugibela izindiza zabo ezilandelayo. Kusukela emcimbini wokuqhuma komklamo ngenxa yokucindezeleka kwekhabhinethi emcabangweni wokuthi unamathele esihlalweni sezindlu zangasese, kukhona imibono eminingi engavamile lapho abahambi becabanga ukuthi izindiza ziphazamiseka.
Akuwona konke okubonwayo ku-TV kuyingozi njengoba kubonakala. Eqinisweni, eziningi zalezi zimo ziyimisebenzi ehlanzekile yezingqungquthela, zenzelwe ukukwesaba kanye nokujabulisa abahambi banamuhla. Nakuba lezi zindabakwane zokuphepha zezindiza zinesisekelo esithile eqinisweni, abahambi bangase bafune ukucabanga kabusha ngamaqiniso ngaphambi kokulahlekelwa ubuthongo.
Izindlu zangasese zezindiza aziyingozi njengoba zibonakala
Izindlu zangasese zezindiza zingenye yezindawo ezivame ukuhamba ngezinkondlo zokuhamba - hhayi nje ngenxa yesimo sabo jikelele. Ngo-2002, i-BBC News ibike icala elibi lomhambi owabambelela kulezi zindawo ngemuva kokushaya inkinobho ye-flush ngenkathi ehlezi. Lo mbiko wabangela ososayensi be- Mythbusters ukuba bazame isandla sabo ngokuphindaphinda inganekwane.
Enye inganekwane evamile ezungeze izindlu zangasese zendiza zihlanganisa i-phobia evamile yabaningi abahambahambayo: izipungushe ezibulalayo. E-mail ye-chain kusukela ngo-1999, umlobi wokuqala uthi unolwazi lokuhlaselwa kwesicabucabu ekuhlaselweni kwezindiza, okubangelwa ukugula okujulile nokufa.
Zombili lezi zimo zabonakala zingamanga ngokuphelele. Endabeni yowesifazane wase-2002 ohlangene nesihlalo sendlu yangasese, le nkampani yezindiza yaqeda le ndaba, ithi lesi sigameko esicatshangelwayo asikaze sibikwe ekuqaleni. Ngaphezu kwalokho, i-Dutch carrier ye-KLM ithi ngenkathi uphawu olungagudluki lwangaphakathi lungabangela izinkinga uma kusetshenzwa indlu yangasese yangasese, izindlu zangasese aziklanyelwe ukugibela abagibeli esihlalweni.
Kuthiwani ngalawo magciwane? Inganekwane yesicabucabu iboniswe ukuthi iyisimo sokungcola, kusukela emininini eminingi yokutshela ngaphakathi komlayezo wezinketho. "Iphephandaba lezokwelapha" elibika lezi zigameko, inhlangano kahulumeni ehlola lesi sigameko, futhi ngisho nesicabangabu ngokwayo konke kwafakazelwa ukuthi iyindabakwane.
Isibani ngeke sikhulise amathuba okuba yingozi yendiza yanamuhla
Ngaphambilini ngo-2015, i-viral video ibonisa lokho okwakubonakala sengathi yizindiza zeDelta Air Lines lapho ibethwa ngombani ngenkathi isemhlabathini e-Atlanta. Lokhu kubangela ukucatshangelwa okuphakathi kwamaflaya okuthi indiza ebanjwe ngombani ngenkathi indiza ingonakaliswa kakhulu, ishiya ukuphepha ukuthi kubekwe eceleni.
Le myth empeleni iqoqwe kwezinye iqiniso. Ngo-1959, indiza ye-TWA yashayiswa yimbani futhi yaqhuma, okwaholela ekuqhumeni okukhulu kwezindiza konyaka. Abakhiqizi bezindiza bafunde masinyane kulesi sigameko, baqala ukuklama kabusha izindiza ukuba zingasengozi kakhulu ezimweni zezulu ezimbi.
Namuhla, ukushayelwa kwemibane kusekhona ezindizayini ngesikhathi esisodwa - kodwa umphumela awubi kakhulu. Ngokusho kwe-KLM, isiteleka sezindiza esiphakathi nomoya singalimaza izinhlelo ezithile zezindiza, kodwa hhayi ekufikeni kwezindiza ukuthi zizocatshangelwa. Esikhundleni salokho, izindiza zanamuhla zisakwazi ukuhamba, kodwa zihlolwe ngokugcwele ngaphambi kokuba zikhishwe ukuze zibuye futhi.
Kungenzeka ukuthi kungenzeka ukuthi i-decompression yezindiza ayinakwenzeka
Esinye isiqephu sezinganekwane sithatha enye yezinto ezikhethekile ezithandwa nguHollywood: ukucindezeleka okukhulu kwezindiza. Ngokwemfundiso: ukushayela indiza ngenkathi kucindezelekile kungabangela ukucindezeleka okuqhumayo, okungahle kuqhekeze umkhumbi wezindiza.
Njengoba ososayensi bathola, kwakuthatha okungaphezu kwesigxobo sezinhlamvu ukudiliza imbobo endizeni. Ngokwenza njalo, isigameko sangempela esithinta i-Southwest Airlines Boeing 737 ngo-2011 kwaholela ekubanjeni umgodi ophahleni lwezindiza, okwenza kube nokucindezeleka ngaphakathi kwekhamera. Kodwa-ke, akukho abagibeli abanjelwe esilingweni futhi indiza yakwazi ukubhekana ngokuphumelelayo nokufika okuphuthumayo, ngokusebenzisa izimaski zomoya okwenziwe ukuphefumula kalula kubagibeli.
Uma amaqiniso ehlaziywa, izindiza zihlala enye yezindlela eziphephile zokuhamba emhlabeni jikelele. Ngaphandle kwalezi zinganekwane zezindiza engqondweni yakho, ukuhamba kwakho kungase kuhambe kalula futhi kungakhathazeki.
