[@Anomaly758] 1) I think the point is Vader didn't wanna just orbitally bombard them. yes the shield could have held out but if they just bombared it no-one would have escaped. From my reasoning Vader wanted prisoners, which meant landing.

2) I didn't know that this was what this particular argument was. Both examples I wanted to find both show there are some superliminal sensors to see the world outside of hyperspace.
