Granted, Im not the biggest WW fan. But when I think in terms of her classic imagery, I see feats of superhuman strength, amazing fighting skills, bracelets deflecting bullets, prowess with her famous lasso, etc. Conversely, WW at the controls of an invisible jet isnt, for me, must-see iconography. And the narrative effort it would take to explain how and why magical/pre-technological Amazons possess a high-tech invisible aircraft isnt, imo, worth the marginal payoff in fan service. Also - as a sfx, cloaking is fairly commonplace now (e.g. Star Trek, Avengers,
Legends of Tomorrow); it doesnt amaze audiences like it used to.
And if WW needs to get into space (not sure why she would) cant Batman provide a lift? Hes the one with all the toys.
