Boeing took the Boeing 787-9 for a test drive at the Farnborough Airshow in 2014. It’s held in Farnborough, United Kingdom every other year. In the off years, the Airshow is held in Paris as the Paris Airshow. If you’ve never been you should plan on attending this year as its pretty spectacular.
Of course the test pilots had to practice the routines before the show. Here’s a video from Boeing during the practice. I’ve never seen the control surface of an airplane move that much from outside the plane. Keep your eyes on the wings.
