Boeing’s new concept hypersonic jet could fly from New York to Tokyo in just a couple of hours
![Old airplanes, including British Airways and China Airlines Boeing 747-400s and FedEx planes, are stored in the desert in Victorville, California March 13, 2015. Last year, there were zero orders placed by commercial airlines for new Boeing 747s or Airbus A380s, reflecting a fundamental shift in the industry toward smaller, twin-engine planes. Smaller planes cost less to fly than the stately, four-engine jumbos, which can carry as many as 525 passengers. Picture taken March 13, 2015.

There's fast, and there's hypersonic. On Tuesday, Boeing unveiled its first concept design for a hypersonic passenger jet during the American Institute of Aeronautics and Astronautics (AIAA) conference in Atlanta. The vehicle could theoretically travel at Mach Five, or five times the speed of sound (6,174 kmh/3,836 mph). At that speed, a flight between New York and Tokyo that currently takes 14 hours would drop to just a couple of hours, according to a Popular Mechanics report.
It's (not) all in the design. So how is Boeing’s design going to be able to reach these speeds? As Boeing’s Senior Technical Fellow of Hypersonics Kevin Bowcutt told Popular Mechanics, the craft uses a specific type of engine known as a ramjet, a staple of many hypersonic vehicle designs. He also explained how the hypersonic jet’s sharp front-end design would produce minimal drag while its split tail would help to stabilize and steer the vehicle.
We’ve already built and flown craft that exceed hypersonic speed, like the Boeing X-51 Waverider, so we know that building something like this one is at least possible. The biggest obstacle to hypersonic flight isn’t creating the perfect design, though — it’s making the flights affordable. So far, scaling it up (bigger crafts that can go for longer periods of time) has just been too expensive. As John Plueger, president and CEO of AirLease Corp., told CNBC, “It’s hard for me to see, at least in the next 15-20 years, that it’s going to be so cost competitive that it’s going to compel the airlines to take a stab at it.”
Lots of plans. No planes. Boeing is far from the only company considering a future in which we travel at Mach Five. In June 2017, Lockheed Martin announced plans to begin development on the SR-72, a hypersonic military aircraft, though it doesn’t expect the craft to be airborne until 2030. In February, researchers in China successfully tested a scaled-down version of their hypersonic I Plane in an air tunnel, reaching a speed of Mach Seven. That craft could also facilitate military operations, a source told the South China Morning Post — if it ever goes into development.
Boeing’s newly unveiled passenger plane could transport soldiers or civilians, according to Popular Mechanics, but both groups have quite the wait ahead of them — the craft likely won’t be ready for takeoff for another two or three decades.
