The basis for the wing is created, so now we can move forward to the front of the spacecraft. To start modeling the front, select two edges located on the side of the wing, as shown in the following image:
With those vertices selected, extrude them three times.
If you have not yet saved the project, now would be a good time to do so.
To finish this part of the project, select only the two edges at the right side of the model, and extrude them along the X axis.
This will be the basis for the modeling of the cockpit.
