Just watched this last night and it was much better than I thought. George took more than some of the sequences - he took some dialog straight from the movie. There is a person named "Hutch", plus some of the X/Y-Wing pilot dialog such as (not 100% exact):
"How many guns (flak) do you think"
"Some on the surface, some on the towers"
"Going in for my attack run"
"Cut across to try to draw their fire"
Many references to "steady, steady"
And, I swear the initial runs of them dropping the bombs - the very idea that it's a pin point attack (too low and it falls short, to high and it skips over the target) is also straight from the film.
The more I learn about Star Wars the more I can see how most everything in the movie is lifted from an earlier film (e.g. the droids being akin to the two bumblers from Hidden Fortress, the Seven Samurai, and now Dambusters etc.)
Also the guys' wife's haircut has mini Leia buns over her ears - didja notice?
