"Did the pilot use a gyroscope on the ball?"
All pilots make use of gyroscopes on their flights, they make up many of the instruments they use to help them fly safely and efficiently, one being the horizon indicator.
"How does a gyroscope work on a ball?"
What kind of question is this? Gyroscopes work on anything...doesn't really matter where they are, they will function.
Here's a better question to ask "if the Earth is curving, how does a gyroscope used on these planes curve with the Earth if gyros remain rigid in 3D space?". There, now that's a good question, the answer is they make use of what are known as pendulous veins. What these do is make use of gravity, to drop hinges on the gimbles on the gyro, that allow air inside to let a sensor know the gyro is out of alignment. A motor then kicks on to provide a torque, that resets the gyro level with surface, until the hinges fall back into place. These hinges open when the gyro drops out of alignment due to curvature or precession. Do some research on pendulous veins, mechanical gyros used on planes in their equipment, make use of these to remain level perpendicular to surface, and they make use of gravity to do it.
I think what you're really asking though, is whether this pilot took his own gyro on a plane to see if it tilts with curvature or not. Well, you'd have a problem again, because all mechanical gyros have friction issues they can not overcome. This friction in the gimbles causes a torque on the gyro which causes a precession, which basically means they fall out of alignment naturally over time no matter what. So even if he did bring his own gyro, there is no mechanical gyro in existence that can overcome friction precession, so the gyro would tilt eventually no matter what...and when it does, how would you be able to tell which is occuring? Precession or curvature? I'm afraid it's not that simple.
