Megafast Planes 

Are you ready to take off with the world’s fastest supersonic aircraft? Strap yourself in for a trip in the Mi G-25 Foxbat interceptor and clock up to 2, 100 mph (3, 380 kmh/h)! Soar in the NAA X-15 rocket plane, which set a record of 4, 520 mph (7, 274 km/h) in 1967! Hop into the world’s fastest jet, the NASA Hyper X-43 scramjet, but hang on-it has the potential to go 7, 000 mph (11, 265 km/h)! Detailed illustrations put you in the cockpits of these mighty, streaking aircraft, while bite-sized facts explain how they work, their pilots’ daring risks, and the thrill of supersonic flight.
