Agreed. Automotive and aircraft designers realized this and proved it with testing long, long ago. Touchscreens are lousy interfaces in any vehicle, but especially one that maneuvers as violently as a fighter plane.
Buttons have to be big enough (or, a control must be usable, whether it's a button or not) in the dark, when blinded, when the vehicle's upside down or spinning rapidly while falling at the same time. By hands that might need to be gloved, right? So, fat fingers.
And you absolutely need to be able to feel whether or not you successfully operated the control. You need to be able to feel the throttle's position along the length of its slot, and you need to feel the switch change when you lower landing gear, or whatever.
Touchscreens take your eyes off of the primary task. No choice; you have to divert your attention to the touchscreen.
