How did it go from 14 to 12 to 5 Y-Yings?
Chop flew 1, slaved 4 others, then Sabine, Rex and Zeb flew 3 more. Thats 8?
I think a few got destroyed when the command center overrode the conveyor belt. I also assumed a few got destroyed in the battle (although I didn't see any blow up on screen, maybe I missed it).
However, 8 y-wings participated in the Battle of Yavin, so where did the other three come from?
We have been told that the ghost crew is not the only Rebel cell so we can assume that others were liberated by other cells.
