Too bad for them, but a relief for the Alliance for sure!
Strange, as Sienar Systems usually creates excellent fighters. The Tie Defender is easily my favorite fighter to fly in X-Wing Alliance, and no Rebel Fighters has both it's fire power, speed, and agility!
But I guess every family has it's black sheep!
May the Force be with whoever designed the thing, because when Palpatine became personally unhappy, someone usually ended up dead!
