[quote]So can my character fly an f18?[/quote]

[quote]Fictional aircraft are not available for use. This would include things such as the Ace Combat 'super planes', like the Morgan or XFA-44 and others, along with planes such as the Yukikaze, or the Firefox. Fictional aircraft of any other kind, such as those on DeviantArt or otherwise, are also not available.  Real-world aircraft are perfectly allowed, and preferred. Models of aircraft that did not make it into full production, such as the YF-23 Black Widow, F-20 Tigershark or the SU-47 would be allowed to be used, and can be assumed to have had at least limited production in the world of Thunderbolt Black.  If you can find some statistics and info on the aircraft, then it will be considered for use in the game, unless it's incredibly obscure, or completely unbalancing or impractical for long-term playing alongside others (for example, the armed versions of the SR-71 Blackbird). Ask if you're not sure.  [/quote]

The F-18 is neither fictional, nor incredibly obscure, unbalancing, or impractical. It fits in perfectly with all of the other aircraft we have, and the game rules as well - I'm not really sure why you needed to ask? 
Yes, you may of course use an F-18 Hornet, Superhornet or EF-18 Growler. Any and all of them are perfectly acceptable aircraft for the game. 

Regarding getting your characters involved, I can see you've more than adequately resolved the issue already - I'll edit my post to include notice by Scott of your characters joining the formation when I edit later today regarding my own aircraft too. It'll be a bit jumbled up, but it'll keep the chronology intact, and then you can meet up with everyone else at the same time with ease. I'll also include mention of your pilots being directed to join the Black Knights as well - the idea in my head, and as fits in with my first IC post, is that all the PC's (player characters) would have been due to join the squadron today, and been notified as such... our home-base being surprise attacked sort of got in the way though, as you'd expect it to.
