It’s also a lot clunkier in the original script. The scene doesn’t show up until the 3rd draft and even then Biggs didn’t exist yet. I’ll have a look in Deleted Magic as well.

4th Draft (Shooting script)
BLUE LEADER: Are you … Luke Skywalker? Have you been checked out on the Incom T-65?
BIGGS: Sir, Luke is the best bushpilot in the outer rim territories.
BLUE LEADER: I met your father once when I was just a boy, he was a great pilot. You’ll do all right. If you’ve got half of your father’s skill, you’ll do better than all right.
LUKE: Thank you sir, I’ll try.

Final Shot Scene
RED LEADER: Skywalker! Are you sure you can handle this ship?
BIGGS: Sir, Luke is the best bushpilot in the outer rim territories.
RED LEADER: I met your father once when I was just a boy, he was a great pilot. If you’ve got half the skill he has, you’ll do alright.
LUKE: Thank you sir, I’ll try.

3rd Draft (unused)
BLUE LEADER: You’re Starkiller?
LUKE: Yes, sir.
BLUE LEADER: Have you been checked out?
LUKE: Yes, sir. I was considered one of the best bush pilots on Sullust. I’ve also had six hours on the T-2.
BLUE LEADER: Six hours, huh? Well, that’s your ship there. You’re blue five. You stay glued to me. I don’t want an independent operations out there. Personally I think it’s foolish for them to be sending fresh kids out on a job like this. This is no joy ride we’re going on.
LUKE: Yes, sir.

Fun fact: Sullust is a planet that was later seen in Rogue Squadron for the N64 and Battlefront II that is a volcanic lava planet that housed an imperial weapons factory which was later abandoned after The Battle of Endor.
