Dirge......nearly the same as Ramjet and Thrust, they were supposedly modified McDonnell Douglas F-15 Eagles, vertical stabilizers on wingtips....non-rear horizontal stabilizers, turbofans on wings for vertical takeoff and landing...etc. But such configurations do not exist. The only F-15 variations I could think of are the F-15E Strike Eagle and an F-15 used for flight testing with a pair of canards just above the intake area. The "DANGER JET INTAKE" marking is used only in US Naval and Marine Aviation, and F-15s are operated by the Air Force. I figured I 'd add the marking just for show.
I've always been a Transformers fan since 1985. I am not a fan of the post-Optimus Prime era/ post-Transformers Movie 1986. I didnt like the story lines, new characters, new villains which looked like some FUBAR creatures from the ocean depths, new voices which were terrible. And most of all I didnt like how Prime died and replaced by a crappy leader. The Protectobots and Metroplex were the only new characters I liked from the cartoon series.
I agree, those are some awesome sketches. I particularly find myself just wanting to *stare* at the first one (even though Slingshot is the only Aerialbot I don't like - it's that nice). I like the way that, to my eyes at least, his markings give the illusion that he's wearing an actual uniform. If you do ever draw any other Aerialbots, I'd love to see them.
