Hey Dragon79....
What do you mean..."If it ever shows", A30-001 just completed its full mission cabin fitout, and is off continuing its mission system flight testing as we speak.
That doesn't mean to say that the mission system testing hasn't been going on for some time, but without the full cabin fit.
And yes, you're right, it uses the UARRSI connection to the tankers flying boom for AAR.
Great little mean machine!
Cheers...FD...
