And about Luke not actually being a great pilot because he gets helped a couple times, agree you forgetting he and wedge are the only ones who even survive?
There’s a Y-wing flying away at the end too.
If only three Rebel pilots survived the DS battle, then who the heck are all these guys?
I presume they were keeping the majority of TIE fighters occupied elsewhere while designated squadrons made the trench runs, and flew off in a different direction once Luke made a successful torpedo shot.
