Ukuba ucinga ukuba i-cocktail eyodwa kwi-flight flight yeso sizathu sokuba ubhekise ubuso obomvu kunye ne-giddy, unokufuna ukubeka ityala ekuqaleni kovuyo lweholide.
Ngama-1930, ugqirha wengqondo waseMelika u-RA McFarland wafumanisa ukuba iziselo ezibini ukuya kwezintathu zonwabile ngeenyawo ezili-10 000 ukuya kuma-12,000 (indawo ephantsi kakhulu kunenqwelomoya ehamba ngenqwelomoya ephezulu emhlabeni) ilingana nezine ukuya kwezintlanu ezinanditshwayo etafileni kwivenkile yokutyela elwandle inqanaba. Isifundo seMcFarland kunye neeapos zijolise kwiziphumo zotshintsho kuxinzelelo lweoksijini olubhangqwe ngenani lezinto eziguqukayo, kubandakanya nokusela utywala. Ekugqibeleni wabhala malunga neziphumo zakhe kwisiqwenga esipapashiweyo esibizwa ngokuba yi-High Altitude: UkuHlolwa kokuLungiswa koLuntu.
Kodwa, njenge Isilayidi yalatha kwindawo yokuntywila enzulu bayenzile ngesihloko, akukho bungqina bezobunzululwazi obuninzi emva komsebenzi kaMcFarland kunye neapos okoko yapapashwa. Ukuzithethelela kwakhe, wayengekho & apos ngaphandle kokuba ayisebenzise le logic kuhambo ngenqwelomoya.
Ke, zithini isivumelwano? Ngaba oku kuya kuthetha ukuba uMcFarland wayecinga ukuba siza kunxila ngokukhawuleza kwinqwelomoya kunasekhaya? Kuxhomekeka ekubeni inqwelomoya yakho ihamba ngokungqinelana neshedyuli.
