A concept aircraft named Skreemr could reach speeds exceeding Mach 10 – that’s 10 times the speed of sound. The design features four wings and two large rockets.
Designers Charles Bombardier and Ray Mattison envisage the craft could be launched using a magnetic railgun system to catapult it into the sky at high speed.Using such a launch system, the craft would be positioned on a pair of conductive parallel rails and accelerated along them using a powerful electromagnetic field.
Liquid-oxygen or kerosene rockets would be fired to enable the plane to rapidly climb higher in the sky and reach Mach 4, which is around twice the speed of Concorde
