Exactly as I've written it? No - there are some very deliberate, and I'd like to think good, retcons in most of the entries. It's not many sentences, but it actually took a while to write because of this. Nothing should be disprovable outright, but if you look hard enough, you'll be able to find the parts I pieced together.
Wow- has all of this information even been compiled before?
I felt that doing the old heroes again with these posts was a necessity due to lazy continuity in the past. For example, I would bet that even the most hardcore fans have trouble visualizing an Alliance that's not all Mothma, Ackbar, and Wedge, or an Empire without stereotypically evil or incompetent leaders. That's because it's rarely been done before. It's as if WEG set this bar with all of this military organization stuff, and no one ever bothered reach for it because they just thought it was good enough. Well, we're reaching.
Squadrons fluctuate, so I decided a long time ago not to put multiple heroes in them like PG did. If you bring Vader and all of his wingmen together without upgrading them, it's essentially the same thing. But the point is, there are more good pilots in the Empire than Soontir Fel, so you have to think of them as more than just wingmen. If you upgrade them, then Black Squadron simply becomes Black Wing, or Black Group. Reorganization like that happens all the time.
A question on the fighter heroes: will Vader's wingmen actually be part of his personal squadron or have their own individual units?
