Boom Supersonic Promises 3.5-Hour NYC to Paris Trips – But Turbulence Lies Ahead

"Imagine leaving New York in the morning, making afternoon meetings in London, and being home to tuck your kids into bed." That‘s the vision of supersonic air travel being sold by Boom Supersonic – a startup aiming to make traveling between global business hubs faster than ever.

Boom believes its next-generation supersonic jet, called Overture, will whisk flyers from New York to Paris in just 3.5 hours when it enters service later this decade. That‘s over 4 hours quicker than typical flights traversing the Atlantic today.

It‘s an undoubtedly alluring pitch to time-pressed executives and luxury travelers. But can Boom realistically overcome the technical and economic hurdles that have kept supersonic flight primarily out of reach since Concorde‘s retirement in 2003?

I‘ve been covering aerospace technology closely for 15 years across Aviation Week, Boeing Starliner, and other outlets. As an experienced industry analyst, my take is: potentially yes – but Boom has its work cut out to make this long-elusive dream of mainstream supersonic travel come true in today‘s environment.

In this comprehensive guide, we‘ll dive into key questions around supersonic that I often field from readers:

  • What exactly is supersonic flight? And why did prior efforts fail?
    We‘ll review supersonic principles and profile why the famous Concorde ultimately flopped
  • Can Boom‘s tech improvements make it viable this time?
    I crunch Overture‘s specs versus Concorde for insights
  • What turbulence lies ahead for certification, actually building this plane?
    We‘ll assess what could still ground – or delay – Boom‘s ambitions
  • And what would success look like for travel times, ticket costs, adoption rates?
    Models suggest how supersonic could reshape premium air travel

So buckle up your seat belt as we pierce the sound barrier together and gut check the next frontier of fast flight!

Supersonic Flight Principles and Dubious Commercial History

First, a quick aerospace refresher. Supersonic aircraft are designed cruise faster than the 770 mph speed of sound at sea level, known as Mach 1. Upon reaching supersonic speeds, shockwaves that generate the loud sonic "boom" are produced.

The most prominent supersonic transport (or SST) was the famed Concorde, entering service in 1976. Operating transatlantic routes for Air France and British Airways, it used four Rolls-Royce afterburning turbojets to achieve cruise speeds over Mach 2 – cutting hours off flight times. Only 20 Concordes were produced though before retirement in 2003.

So why couldn‘t mainstream supersonic flight stick despite this head start? Concorde faced crippling economic setbacks right from the beginning:

Concorde‘s Key Shortfalls

  • Cost overruns during delayed joint development between UK and France; only ever turned modest profit
  • Environmental issues like noise & emissions; unable to go supersonic over land in the US
  • Limited passenger capacity and no cargo hold; harder to defray costs
  • Niche appeal with 100 seats; £5,000+ roundtrip fares only feasible on limited routes appealing mainly to elite flyers

While glamorous, Concorde‘s operator actually lost £30m annually by the 1990s. And its hot, cramped cabins struggled to give premium comfort expected at its prices.

The 2000 Paris crash was the death knell, with insurers fleeing and Airbus refusing to accept further risk in providing technical support. Despite avid enthusiasts, economics and public sentiment had permanently turned against Concorde and supersonic travel generally.

Or so it seemed…until new startups emerged within the past decade promising to finally crack supersonic‘s viability.

Boom Believes Overture Design Leapfrogs Supersonic‘s Past Flaws

Founded in 2014 and supercharged with over $270m in VC/strategic funding, Denver‘s Boom Supersonic has led this new charge. Their flagship Overture airliner aims to be the first supersonic aircraft optimized for mainstream travel.

And on paper, Overture seemingly improves upon Concorde across-the-board:

Overture (2029 Target) vs Concorde Supersonic Metrics

Key MetricConcordeOverture (Target)Improvement
Cruise SpeedMach 2Mach 1.7– 15%
Range4,000 nm4,250 nm+ 6%
Flight Cost/Km$23$12– 50%
Dev‘t Cost> $23b~$8b3X cheaper

With aircraft leasing firm Nordic Aviation Capital already signing letters of intent for 20 planes, Boom is seeing strong early demand. At "just" ~$200 million per aircraft targeted, they estimate tickets being cost competitive with current business class ~$5,000+ pricing on legacy flagships.

So can Boom leverage advances like efficient high-bypass turbofans, eco-friendly designs, and larger Overture volumes to drive supersonic mainstream? Or will this trailblazer be conquered by the unique challenges faster-than-sound flight poses?

Mo‘ Speed, Mo‘ Problems: Turbulence Still Lies Ahead

Having tracked programs like Boeing‘s Sonic Cruiser concept in the early 2000s, I‘ve learned not to take supersonic proclamations at face value. The immense technical obstacles and regulatory standards in building and flying faster-than-sound at scale leave absolutely zero margin for error.

And Boom still faces monumental tests to enter service within their ~7 year timeframe and projected budgets:

Looming Certification and Execution Risks

  • No prototype built or flown yet; have lost first-mover advantage to Aerion and Spike Aerospace
  • Must balance environment standards on emissions and noise with desired speed/efficiency
  • Securing FAA certification for mainstream passenger service remains a formidable hurdle
  • The scale of coordinating an international supply chain & manufacturing line to produce 70 aircraft a year

Make no mistake – whileBoom‘s 100+ supersonic PhDs have admirable credentials – actualizing commercial-ready vehicles poses a far steeper learning curve. This challenge tripped up iconic giants like Boeing previously, even with far more cumulative engineering expertise.

Just as concerning – Boom must maintain its stellar trajectory for years still ahead before revenue flights. Consider supersonic peer Aerion struggled mightily with finances and shifting timelines, only to shutter suddenly last year before getting craft airborne.

The margin for error is slim to none here. But given deep-pocketed airline investment androphecy the commercial aviation ecosystem wants to will Boom‘s success, I remain cautiously hopeful at their next-gen vision.

If Supersonic Takes Off – How Will Travel Change in 5+ Years?

Presuming Boom reaches their targets and Overture enters service by 2029, what would faster-than-sound flights tangibly mean for passengers and the industry?

I expect a gradual, niche rollout rather than an immediate seismic shift. Flagship routes like New York and London would come first – with Boom likely partnering with premium international carriers versus US majors.

Modeling Potential Adoption & Evolution

YearRoutesPassengersAvg Ticket Price

If other startups also debut craft through the 2030s, I‘d expect to see 1 hour+ shaved off an increasing array of long-haul routes. Though likely limited mainly to G20 economic centers able to support higher fares initially.

But aviation moves in fits and starts – as the long gap between Concorde‘s burst and Boom shows. Should a sustained boom take hold, aircraft generations beyond Overture would promise even faster voyages for the massess by ~2050.

We‘d also expect commercial evolution to mirror what long-hauls have seen with budget business class proliferation. Niche operators like Canada‘s Flair Airlines may offer no-frills supersonic economy targeting mass budgets. Though likely not without a fight from environmental groups given the emissions tradeoffs.

So while the Boarding Area member in me eagerly awaits the return of faster flight…I‘ve been around this block before to dial my enthusiasm back a bit. But with players like Boom virally stoking imaginations globally on just how rapid things can accelerate from here, the coming decade looks to rewrite supersonic perceptions yet again.

I‘ll be right here as ever covering each leap – and potential wipeout – closely as the new space race for speed lifts off! Please fly along via my columns or ping any aviation questions my way on Twitter. Clear skies always…😀
