This week's Question: Canadian industrial designer Charles Bombardier has developed an aircraft concept that, in theory, could send passengers from London to New York in 11 minutes. The "Antipode" would have a scramjet engine and wings fitted with rocket boosters, propelling the aircraft to 40,000 feet and enabling the aircraft to reach Mach 5. To bring the concept to reality, engineers are challenged with addressing sonic booms as well as the materials' resistance to high heat. A proposed aerodynamic technique called long penetration mode (LPM), however, would use a nozzle on the aircraft's nose to blow out air and cool down the surface temperature, while also muffling the noise made from breaking the sound barrier. The design is decades away, according to the researchers. What do you think? Will "Antipodes" take off?
