Still to fast. They are starfighters, fastest shit they have, in a place where 50 miles is nothing. They move more than likely in excess of 2000 mph, in order to do anything. Atmosphere will slow it down, but if they go in for a strafing run, they will slow down, yes, but the timing required to hit a neck on a moving target from several miles away, even with a targeting computer, would take some amazing flying. Only a couple people could do that if they had to. Stands to reason therefore even if they had known that, only Rogue would have attempted it.
And yeah, i knew they had torpedoes, but they come in limited supply and move slower than lasers. Thats like having a fighter fire a missile at a tank from a couple hundred feet in the air, even with radar guidance its not even close to an assured hit.
