This jet model has both exterior and interior. The model is rigged and has many bones/nulls which is controlled by one object/empty cube. When you open .BLEND native file in Jet XTB collection you will find Collection 1 where you will see Jet Airplane (thats the main controller) I have uploaded video of simple animation and cockpit movable parts.
This model is not animated but it is rigged so you can animate it as you want. There are small knobs and toggle switches and buttons and pointer of meter you can animate just for entertainment or detailing. You can adjust cockpit seat's angle. You can animate lever and meter on it. You can see the video above on how to animate. Clutch/Pedal whatever is present there to animate. Unfortunately doors are not rigged to any controller so you have to rotate and animate them on their mesh that's simple. This plane is partially rigged (not fully rigged)
