Kukho izinto esingasoze siziqonde kakuhle: indlela isonka esijika sibe yi-toast, kwenzeka ntoni kwiikawusi ezilinganayo kwindawo yokomisa, kwaye zisebenza njani izindlu zangasese kwiinqwelomoya.

Kodwa ngomoya wokudelela iimfihlelo zearcane zendalo iphela, sajonga ekutyhilweni kwemfihlakalo yendlu yangasese yendiza.

Inkqubo yangasese yendlu yangasese yenziwe nguJames Kemper ngo-1970. Ngaphambi koko, abakhweli kwiinqwelomoya babekwazi ukuya kwimisebenzi yabo kwibhakethi le-slosh, elaliza kuthi lihombise igumbi lokuhlambela xa inqwelomoya ibetha isiphithiphithi okanye ukhutshwe ngefestile kunye nomhlaba kumhlaba ongalindelekanga ngezantsi.

Inkqubo yokufunxa i-Kemper yaqala ukubonakala kwinqwelomoya ye-Boeing ngo-1982. Inkqubo yayixhomekeke kulwelo oluhlaza okwesibhakabhaka-olwaziwa njenge-Skykem-isambatho esinganyanzelekanga, kunye nokufunxa.

Xa ucinezela iqhosha lokugungxula, ivalve ivula ezantsi kwesitya sangasese kwaye ichaze indlu yangasese kwi Umshini womoya . Umshini wendlu yangasese ujikelezisa imixholo yawo uze ubeke yonke inkunkuma eqokelelweyo, kunye nencindi eluhlaza, kwinkqubo evaliweyo yenkunkuma.

Nangona kunjalo, ngokuchasene nenkolelo edumileyo, ukapteni wenqwelomoya akanakho ukubamba itanki yangasese aze ayithumele isihla phakathi kwenqwelomoya. (Xa abantu benika ingxelo yomkhenkce oluhlaza okwesibhakabhaka owela phezulu, kuhlala kuyinto nje evuzayo kwitanki yogutyulo lwetyuwa okanye ityhubhu yokukhupha amanzi emisa emkhenkceni.)

Ekupheleni kwenqwelomoya, ukufunyanwa kwendlu yangasese kugalelwa kwenye itanki ngasemva kwilori. Ithe yakube ikhwele etankini iloli igcwele, ikhutshiwe nayo yonke intsalela inkunkuma evela kwisikhululo seenqwelomoya. Apho isuka khona iyamangalisa ngakumbi.
