in 1.11 beta:
-make your fuselage body with hollow fuselage
-keep in mind where you want to later have the cockpit so have fuselage sections that are the correct length and placement for where you want to cut.
- Size and build the fuselage beforehand and as if the cockpit doesn't exist (i.e don't have it dip down where the fuselage starts but instead smoothly transition over
-use fuselage slice to slice away an opening for your cockpit

or if your non beta then, idk wha to tell you
