Spicy recaps

at the speed of sound on land 🚀🌍 This simulation shows what it would be like to ride a supersonic train across Japan at Mach 1 (1,330 km/h). Today’s fastest trains reach about 320 km/h, while maglev technology has crossed 600 km/h. Future technologies like magnetic levitation and vacuum tubes could make supersonic ground travel possible. 🚄✨
