Lugg said at the 2011 Paris Air Show he plans to get the plane airborne by June 2021. It would reach speeds of up to Mach number 4.4 (3,431 mph (5,522 km/h)) and fly at an altitude of 60,000 feet (18,300 m). The propulsion is projected to be 30% more fuel efficient than the Rolls Royce/Snecma Olympus 593 Engine in the Concorde. The SonicStar would, hypothetically, fly at twice the speed of the Concorde. It is planned to be powered by two (theoretical) 54,700 thrust SonicBlue S-MAGJET (Supersonic-Magnetic Advanced Generation Jet Electric Turbine) hybrid supersonic 4000-X series engines. Some sonic boom is planned to be avoided through electromagnetic drag reduction[vague] technology (currently not in existence), eliminating the infamous hallmark of the Concorde predecessor.
