I tried your method, and I do seem to get closer behind the A-Wings, but these little ****ers turn fast! I think it's the hardest mission (yet, at least). I'll come back to it later, when I'll get more experience.
The hard part when playing with a mouse is when a fast ship (like the A-Wing) does large circular turns, because you need to shuffle the mouse chuck-chuck-chuck-chuck to keep on track. It must be fun to play this on a port for PSP or whatever. Hmmm.... Maybe it would be impossible to see the enemies from far when they are tiny moving dots.
My fave Historical is Ackbar's Rescue (yet), because I love to fly through the Shuttles while trying to identify them.
