[1.21.1] attempt to build "Northrop P-61 Black Widow"

Note:
I don't recommend doing this in survival mode, although it's possible. This requires fueling 23 portable engines, and I strongly recommend installing the "Copycats + Aeronautics Weight" mod. There are too many Copycats resources.

Controls:

• WASD - basic moves

• 'Spacebar' - turns engines on and off

• 'Shift' - lowers and retracts landing gear

• 'Arrow Up' - increases propeller power (max: 13 power)

• 'Arrow Down' - decreases propeller power
