Did you see how "fast" the balloon travelled? No. You saw merely an optical illusion in commercial TV!
The only fast thing was the helicopter with the TV camera on board. They broadcasted a telezoom closeup photography of the small balloon so it looked larger. The helicopter circled fast in a large bend around the slow balloon. Nothing more.
Remember how often the TV reporter pronounced live on air: "See how incredible fast that balloon goes!"
