Get the TIE Fighter in the Imperial Academy Heist mission on both night and day versions. Then, complete the level.
Information in this section was contributed by Daniel Howard.

In the day version, after you disable all of the sensors, fly to the right over the mountains. You must find a large open space with a single comm tower. Disable the comm tower with your ion cannon, then look near the base of the tower on the left for the TIE fighter. Shoot it with your ion cannon and it will take off, fly a short distance, and land. The rebel icon will then appear over it. Switch to it and then fly to the main base. Switch to the Imperial Shuttle and fly to the level exit.

In the night version, sneak past all the sensors. Turn right into the narrow valley that appears on your radar near the last sensor. Fly to the large open area. Once there, fly along the mountains on the left (staying low to avoid detection) until you reach a narrow valley on the left, which you will see on the radar. Fly into that valley and follow the way to another open area. Look for a single building and shoot the enemy pilot on the left side. The rebel icon will then appear over the TIE fighter, which is on the other side of the building. Switch to the TIE fighter and head to the main base. Switch to the Imperial Shuttle, then follow the radar back to your Snowspeeder to pick up your co-pilot. You will fly a bit past the normal level exit. A intermission sequence will be triggered, featuring you picking up your co-pilot. The level will then end.
