For a non toon accurate design you might argue that (though I and most toon fans would probably disagree). But given the lengths they went to in making the jet mode insanely toon accurate, no matter how far that is from any kind of aerodynamic logic, the decision to exclude the iconic cockpit in jet mode is unfortunate. It’s one of the things that makes me prefer Ditka’s tank mode. I had to check screenshots to count how many wheels he should have but the missing cockpit was instantly noticeable. YMMV of course.
