[quote=@Silverwind Blade]You mean something like a Hawk (as an example); light fighters or combat-capable trainers? By all means, yes.

No I meant helicopters powered by jet engines.

Yeah. Light fighters, combat-capable trainers, or combat variants of trainer aircraft.
Had found such an aircraft and really liked it. But didn't put much work into the sheet as I wasn't sure if they'd be allowed. Will get working on it. Downside now is deciding on two characters or the backseat computer option.
