As it stands ROTJ arranges many of the characters in dioramas without having any human reason for them being there.

It's like Lucas is a kid playing with action figures rather than people going through a planned sequence of events with unexpected obstacles and distractions.

And in the original 1977 film where Luke (Who has never flown an X-Wing or starfighter before) is leading the trench run with two much more experienced pilots as his wing men is totally fine.

Luke leads the trench run because he is the hero that we are all rooting for. It makes no sense logically but it feels so right.

The same can be said of all the characters being made instant generals in ESB (Plus Lando in ROTJ). It's daft but oh so cool. Of course in the real world Mon Mothma wouldn't get Lando to lead the final battle against the Empire. But it's totally awesome, infact if I could be one character in the whole of the OT it would be Lando in that epic battle. With films this much fun logic can go hang.

Would you send a panicy golden robot on a covert mission on Endor... nope. But then we would be deprived of the delight of Threepio shouting "Come baaaaack!" and "R2 stay with me".

Would our heroes have realistically escaped detection for most of the time they are on the first Death Star? Absolutely not, it's flat out insane, do I care? Nooooo.
