Supersonic Flight: The Future of Fast Travel? 
Supersonic
commercial aircraft were going to revolutionize the travel industry. The
Concorde flew from London to New York in three hours, less than half the time
of sub-sonic airliners. As technology improved, the aircraft would get faster
and larger, shrinking time in the air so much that a businessman could hop on
at breakfast time in New York, have a late-morning meeting in London followed
by lunch, and be home in time for dinner.
It didn’t quite turn out that way.
The Concorde, developed jointly by the British and French, went into service in
1969 and flew its final flight on November 26, 2003, victim of high operating
costs and safety concerns. Today’s airliners can reach about 85% of Mach 1, the
speed of sound, but stay comfortably short of that barrier. That might change
in the next few years, according to the Robb Report.
Boom Supersonic, which started in
2014, has just become the first U.S. independent company to fly a prototype
commercial aircraft faster than the speed of sound. Late in January, Boom’s
XB-1 experimental jet reached Mach 1.122 (860.67mph) in test flights over the
Mojave Desert, the same place where legendary pilot Chuck Yeager broke the
sound barrier for the first time back in 1947. It was the 11th
manned test flight for the aircraft over a 10-month period.
Without receiving grants from the
U.S. military, which many considered essential to develop a supersonic
airliner, Boom got the job done. Its founder, Blake Scholl, said the flight
“demonstrates that the technology for passenger supersonic flight has arrived.”
The next step is to scale up the technology used in the XB-1 for the company’s
airliner, the Overture. “Our ultimate goal is to bring the benefits of
supersonic flight to everyone,” says Scholl.
The Overture will be much larger
than the XB-1, designed to carry up to 80 passengers. Boom expects the first
commercial flights of the aircraft will be in 2029. A production facility is
going up in North Carolina. The airline industry is on board; Boom has received
130 orders and pre-orders from American Airlines, United Airlines and Japan
Airlines.
Plans are to produce up to 66
Overtures per year. Many aviation experts think that’s not feasible,
considering that Boom was forced to build its own supersonic engines after
major aviation engine manufacturers turned down the project. Boom went ahead
anyway, designing its own engines in-house, and it looks like they work.
Already, Boom has long outlasted its better-funded competitor, Aerion, which
spent 20 years developing its own project only to abruptly shut its doors in
2021, citing little investor appetite in the supersonic concept.
The XB-1 is doing more than just
proving that Boom’s engines work. The aircraft is also testing multiple
technologies that will be aboard the Overture, including an augmented-reality
vision system and digitally optimized aerodynamics. The aircraft is made almost
entirely from carbon composite materials, which allow the designers to shape it
more precisely.
What will
it cost to fly aboard the Overture? That’s anybody’s guess right now. In 1977,
during the Concorde’s heyday, a one-way ticket from New York to London, or vice
versa, ran about $3,000 in today’s dollars. The cabin was cramped, with narrow
seats, few amenities and the noise level was unacceptably loud by today’s
standards. Boom has undoubtedly studied that aircraft and its history, and has
the benefit of technology that’s half a century beyond Concorde.
Another
challenge facing Boom, and any other company that will want to get into
supersonic passenger travel, will be possible restrictions on flying over
populated areas. When an aircraft breaks the sound barrier, a sonic boom is
generated, which is why Concorde was restricted to flying across the ocean. After
taking off from Heathrow or JFK, the aircraft wouldn’t go supersonic until it
was over the water. While transoceanic flights will certainly be the primary
market for the airlines who will fly the Overture, they’ll certainly want to
eventually move to overland routes like New York to Los Angeles. Today, a
JFK-LAX flight takes just over six hours. Aboard the Overture, that could be
reduced to just three. It doesn’t take a crystal ball to see that there would
surely be a market for that kind of flight.
For
now, though, good old-fashioned subsonic airliners will take you pretty much
wherever you want to go, and we’ll help you get on board. Give us a call!
