That Pitol certainly had pretty good control over his bird.
I doubt he was showing off or even knew he was being watched.
As for spilling a little water, I figure the objective is to get as much water on the fire as quickly as possible and he seems to have done that. It wasn't like he was going to run out of water from that river any time soon.
A few years back, I watched a fellow in a skid-steer clearing snow from a parking lot.
He worked quickly and maneuvered his vehicle like it was a part of him.
At times, he spun or cornered fast enough to lift a couple wheels off the ground but never looked like he was not in total control.
He would move snow, add it to the pile and shape the pile in a way that seemed like he was just doing it with a giant trowel.
This pitol kind of reminds me of that fellow. He just maneuvers his vehicle without having to think about it.
