Introduction to the Polar Express: The Polar Express combines the aerobatic movements of fighter jets to simulate the physical and mental experience of a pilot, including rolling up and down, spiraling, and diving at extremely high speeds. Like an eagle striking the sky, like a sword pointing at the sky, the strange backwards and upwards and swift dives make the spectators happy and amazed, and bring the sitters the thrilling joy of weightlessness and centrifugal state!
