Airbus is doing the trials.

That makes sense. I also wouldn't be surprised if Airbus was repainting
the livery as it flys around the world. It sure makes it more appealing
to buy a new plane when you already see it out there with your name
painted all over it. Maybe your customers will even hear about it in
the news, think you are already buying one, and generate an expectation
that you will.
