I think I know what mission you're talking about...
all I can say is: why didn't they let you fly the Otana?
1. Fly past Golan station, avoiding detection.
2. Fly into outpost, without getting too close to the TIEs.
3. Board outpost, wait for "Docking Complete" message.
4. Call reinforcements.
5. Escort the SHU then blast the living sh*t out of the imps
6. Remember: the outpost is invincible, so if you get low on shields...
Why is it that whenever someone says SOL I am always in trouble... whether it be Standards of Learning or (the other version). I'm always screwed.
