Ngokwe-theorists yelenqe, loo mafu amhlophe amnyama afafaza ii-jet iinjini ziikhemikhali (ukuncoma kukarhulumente) ezisetyenziselwa ukusigulisa. Inyani ayisiyonto ihlazisayo: Izichaso, njengoko zibizwa njalo, ziyindlela nje yokunyibilikisa eyenzeka xa kushushu kwaye kufumile ukufuma kwenqwelomoya kubetha ixesha elipholileyo lomoya-impendulo efanayo eyenzekayo xa ubona umoya wakho kubanda ntseni.

Izithintelo zenziwe ikakhulu nge-crystalized H2O (umphunga wamanzi uyimveliso yokutsha kwiinjini zejet) ukuze uphumle ngokulula ngakumbi ukuba ubucinga iiplawu zomsi kunye nomsi ohleli apho phezulu kwindawo yokuhamba ngenqanawa. Nokuba imigca emhlophe iyabonakala emhlabeni okanye ayixhomekekanga emhlabeni kuxhomekeke kubushushu beatmosfera, kunye nento ebizwa ngokuba 'luxinzelelo lomphunga' utshilo umqhubi uPatrick Smith, umbhali I-Cockpit iyimfihlo. Xa umoya womile, ii-contrails zinokuvela ziphume ngaphakathi kwimizuzwana okanye kwimizuzu, ngelixa iimeko ezininzi zokufuma zinokushiya ilifu elichaseneyo lihlala isibhakabhaka iiyure. Ukuba kukho ukufuma okwaneleyo emoyeni, iindlela zinokude zikhule ngobukhulu — ukuya kuthi ga kwi-400 yeemitha ukuphakama.

Ukuchaphazeleka kwendalo kokungqubana kuya kuhlala kubonakala, nangona ezinye iingcali zixhalabile ukuba amafu enziwe ngabantu anokuchaphazela utshintsho lwemozulu. Izithintelo zihlala zakha i-cirrus (cinga: ephezulu kwaye ibhityile) amafu, utshilo uSmith, kwaye ukogquma okungaphezulu komoya kunokuchaphazela ubushushu kunye nemvula. Kodwa thina unako Ukuqinisekisa ukuba ayilulo uhlobo lwenkqubo yokutshiza eyimfihlo ngurhulumente-nokuba uKylie Jenner ucinga njalo .
