- Cliff Secord, brash young air-circus pilot
- Charlotte Steele, founder of the Hollywood Knights (the militia, not this)
- Reginald Creighton-Laysworth, a former air pirate who is either British or just pretends to be
- Jefferson Reid, Ace American
- Moxie Boyd, girl genius
So if you're keeping track, that's the protagonist of a contemporaneous film, a canon character from Crimson Skies lore, two Thrilling Adventure Hour characters, and one lone original character who is either a pathological liar or kinda off-kilter. I'm aware that Robo himself could've been a PC in this game, but I didn't want to stray that far from what people might recognize as Crimson Skies (he said, shortly after admitting he'd put the Rocketeer in his game).
I'm looking forward to this game.
