He toki roa tipu mai ko ngā wāhanga rerekē kei roto ia, he pito whakapuaki . Ko ēnei wāhanga hei hanga i te hā o te hā o te wāhi nui. Ka whanake i te wā, ka whakamahi ngā kairangahau i tēnei pihanga whakawhanake kia whakamātau i ngā mea pērā i ngā waka manu e turu ana i te rere nui, ā, hoki hākuhā ki te mōhio i te mea ko ngā rererangi e haere ana ki te anga whakarunga. He mea matekiteki tēnei i te ao i te mea e whai ana i te mōhio i te mea e pa ana i te waka manu!
Hei tauira, i te wa kua haere te waka roroa i runga i tenei me te whakatupu i tetahi pungawerewere nui e mohiotia nei hei ‘pungawerewere whatu’ - ka kite ia i te whakapae i te paenga (o). Ka puta te reo i te wa ka haere te waka roroa i runga i te rahinga o te reo. Ka taea e nga kaihanga rangahau te whakatau i tenei waa i roto i te paepae whakapakari. Kei a raro hoki ratou i te moemoea i hea atu ano nga mea ka taea e ratou i ngaihere, penei me te mea ka haere i waho i te pungawerewere nui nei. Ko tenei ka tuhia e ratou, ka hangaia he wāhi noho reo kore kei runga i te rangi i ka maumahara ai e katoa.
He whai hua anō hoki ngā tūru whakapae mō te whakaaro i ngā mahi āerodinamika o ngā rupu katoa i te pīrangi. Ko te āerodinamika, nō reira te matataki i te mea e haere ana i roto i ngā hau me ngā wai, he mea nui hei whakangungu i ngā waka rangi kia tu tonu ki runga, ngā raketa kia tango ki te anganga, me ngā race cars kē kia haere ake i te 200 maila ki te awa. Ko tēnei whakaaro he mea nui mō ngā ingenihi kia hanga i ngā hanga hou me te pai rawa.
Te arai kumi kia whiwhi i te hunga kairangahau ki te āhei ki te whakarerekē i te ara hau me te kite i te mea e whakahē, e riro, neu atu. Ka whakaae atu ia ki te whakatū i ngā waka pai ake ka āhei ki te haere ake me te whakaiti i te waihotanga e whai ake nei i te take i kitea ai. Ki te hiahia hoki ratou ki te hanga i tētahi waka rangi hou e pai ake ana, ka taea te whakaatu i te painga o tana rapa ki tana āheinga me te nui o te pūnui i whakamahia e ia.
Tētahi āheinga i āna i tae noa ai he mea hīkoi i ngā raraunga ki te ātetenga o te waea. Ko tēnei e whakaaetanga ana i a rātou i hea kia taea e ngā pūwhenua rānei, ngā pūkaha rānei te mahi i ēnei ātetenga, kāore i roa rawa te werohia rānei. Ko te mōhio i ēnei āhuatanga he mea nui mō te tūroa o te haere, ā, mō te mea hoki ka hiahia tātou ki te whakapiri ki waho i tō tātou ao.
Ka tomo rātou i tētahi hau, pērā i te harakeke (kāore ia i whakaae ki te whakamārama i te ahua matua o tēnei hau) ki tētahi taha, ka whakanuia e ia i runga i tētahi pitanu. Ka noho te hau, i te wā e tukuna ana; ka whaiwahia atu ki ngā tonu katoa hei hanga i tētahi pakipaki hau. Ka haere tēnei pakipaki hau ki runga i te pūoro hei tutuki i tētahi pae whati -- ka puta he wāhi nui rawa atu i te werawera me te pausanga hau e mōhiotia ana ko "test gas".
Ki reira, ka taea e ngā kairangahau kia whakamahi i tēnei hā o roto i te whakamātau i ngā mahi a ngā rerekē tuatahi i te waewae tūpūtahi rānei, nō reira i ngā āhuatanga taiao rerekē. (Tauira: he kōwhaiwhai raupo rānei, he kōrero me te hā o roto i te whakamātau) Ko tēnei he haere i runga i te mōhiohio e whai ake nei hei whakamahi i te hanga i ngā waka hou me te mōhiohio atu i te pūnaha hoki ki te mōhio i te pai rawa i te waewae tūpūtahi.
