And to counter a earlier point I don't think this is a production aircraft - but style in the prototye stage as the winner hasn't been decided.
The aircraft in question would probably have been en route to Australia for delivery to the RAAF this week if it weren't for this incident. KC-X is the American program.
EDIT: You can even see "Royal Australian Air Force" and the kangaroo roundels stencilled on the airframe in the images I posted.![]()
And we can't really complain about this. Boeing is still dicking around with the Wedgetails.
