There are a shitload of fighter pilots in the crowd. Uh, didn’t every pilot except Luke, Wedge, and whoever was in the only Y Wing left sort of get sploded during the battle? Where did all these other pilots come from? It can’t be they were holding them in reserve, because what reserve, they were seconds away from being utterly obliterated by the d-star, there was no point in keeping reserves.
They aren’t all pilots; it’s like Star Trek, where everybody from any given planet wears exactly the same clothing. The guys who were flying the fighters happened to be from one planet, and everybody from there dresses in flight suits.
So they were all from Tatooine, since that’s where Luke and Biggs were from and they were wearing the suits. I see. Odd such a remote dustball at the ass end of the galaxy would prove such fertile recruiting ground for the rebellion!
To those saying they came from other bases (and yeah, I never disputed they had more at other bases, clearly since they had more on Hoth in Empire), that’s probably the most logical answer, but seems like it wouldn’t fit with the timeframe unless they waited an oddly long time to hand out the awards and didn’t instead use that time to evacuate their no longer secret base (even if not in immediate danger from the d-star anymore, there are still plenty of Star Destroyers that could jump in and wreck their steez).
