Impressive, for an airliner.
However, a WW-II Mustang pilot is laughing in his beer.
Not to mention an Eagle, Falcon, or Raptor pilot.
Not to belittle Boeing...which builds the best airliners, bar none.
I doubt laughing, a pilot would understand how much thrust it takes to do that. Probably drooling to have that engine in his little mustang. It would look a little funny though.
Impressive demonstration of the 787!
I’ve seen film of the Sikorsky CH-53 doing loops, barrel rolls, aileron rolls and a Split-S. The aileron roll was also filmed from the cockpit.
Sometimes manufacturers will pull out all the stops (to use a musical analogy) to demonstrate their product!
BTW, sitting still on a runway, side-by-side, the CH-53D would beat an F-4 Phantom to 4,000’ altitude, an A-4 Skyhawk to 5,000’.
