Maybe it's one of the bombers on the Volition Bombers desktop. Or maybe....the government made them take it out because it too closely resembled one of thier super secret projects.
Ok seriously, stupid as that sounds.....
A few years ago i saw a revell model for the SR-92 Aurora spy plane. I went back a week later, none were left, never got more in, and you can't find it on Revell, Monogram, or MPC. The government does deny the existence of that plane.
so what do i think bomber 02 is? I think it's sitting under the wrecked hades in the opening cutscene of fs2, squashed, and they thought...well since we are squashing a bomber that doesn't exist, let's put it under the hades, which was destroyed near no planet. Mystery solved.
