China’s hypersonic missile test ‘went around the world,’ according to top U.S. general

The transcript discusses a hypersonic glide vehicle tested by China, as reported by General John Hayden. The vehicle, capable of traveling at five times the speed of sound, missed its target by 40 kilometers but raised concerns in the US about China's technological advancements. Unlike ballistic missiles, hypersonic glide vehicles maintain a lower trajectory and can maneuver within the atmosphere, making them harder to detect and destroy. The new missile system, classified as a Fractional Orbital Bombardment System, can fly over the South Pole, bypassing most US missile defense systems aimed at the North Pole.

What is the significance of the vehicle missing its target by around 40 kilometers?
