  • In the 1950s, a flight from London to New York was a grueling 13 hours.

  • All the while enduring the noise and vibration of piston engines and that occasional white-knuckle

  • ride through a North Atlantic storm.

  • And then

  • Along came jetliners.

  • They flew above the weather, and a flight from London to New York was cut

  • to just seven hours.

  • The Jet Age revolutionized air travel.

  • But an even bigger leap forward was just around the corner.

  • In the upcoming supersonic age, airliners would travel twice the speed of sound, and

  • fly right at the edge of space.

  • Cutting a trip from London to New York down to just three and half hours.

  • It was supposed to be the next giant leap forward.

  • But instead, going supersonic would end up as one of biggest missteps

  • in commercial history.

  • In 1947, a rocket-powered plane breaks through the sound barrier.

  • The first time in history an aircraft is recorded flying faster than the speed of sound.

  • The monumental achievement tputs to rest doubts about whether man or machine could even withstand

  • supersonic flight.

  • And it was just the start.

  • New speed records quickly followed as supersonic flight became widely understood.

  • And it wasn't long before military aircraft were routinely flying

  • well beyond the sound barrier.

  • If a commercial airliner could be built to do the same, a trip across the Atlantic could

  • be cut down to just a couple hours, pulling the world closer together.

  • But flying at supersonic speeds requires engines at least twice as powerful

  • as those on subsonic jets.

  • Streamlined wings and airframes, and materials that can withstand the high temperatures caused

  • by air friction.

  • With these technical hurdles, there were doubts about whether supersonic

  • air travel made any sense.

  • But only a decade earlier, there was similar skepticism around the switch

  • from props to jets.

  • Even so, the transition to jet age happened quickly and it left many aircraft builders

  • behind.

  • The upcoming supersonic age could end up doing the same.

  • In 1949, the British stunned the world with the first jet airliner.

  • It flew faster and higher than any airliner before it.

  • The Comet was revolutionary, and with it, the British were going to lead the world into

  • the jet age.

  • That is, until a design flaw caused a string of deadly accidents, temporarily grounding

  • the Comet.

  • Which gave the rest of the world time to catch up.

  • By 1960, for every Comet sold, the Americans were selling another ten jetliners of their

  • own.

  • And the British quickly lost their early lead in the jet age.

  • But if supersonic air travel was the next evolution, Britain would have another chance

  • to retake the lead.

  • By 1961, the British had come up with an early design for a supersonic airliner.

  • At the same, the French were also working on a similar concept.

  • As both efforts advanced, it made sense to join forces.

  • And after a little creative deal-making and political maneuvering, the two countries partnered

  • to launch the Concorde program, signing a treaty in 1962.

  • Britain and France, once fierce aircraft-building rivals would now work together to reinvent

  • air travel.

  • Thousands of the brightest French and British engineers were put to work making supersonic

  • air travel a reality.

  • Aside from maybe the Apollo moon landings, Concorde was the most technically ambitious

  • project of the century.

  • It would cruise at twice the speed of sound, with enough range to fly across the Atlantic.

  • Although it would burn more fuel, Concorde would make two flights in the same time a

  • regular jet could make just one.

  • Offsetting higher fuel costs by reducing the number of aircraft needed for each route.

  • By 1963, mockups were capturing the world's imagination and dazzling the press.

  • And Airlines placed orders for more than 70 Concordes.

  • A number expected to grow to at least 200 by 1975.

  • And beneath Concorde's elegant lines was triumph of engineering.

  • It's delta wing took over 5,000 hours of wind tunnel testing to perfect.

  • An ingenious shape that allowed Concorde to fly beyond Mach 2, but also slow enough to

  • fly into existing airports.

  • Afterburning turbojets were sourced from a Cold War-era bomber.

  • But they were re-engineered with an innovative intake system that allowed for cruise at supersonic

  • speeds for longer than aircraft in history.

  • With a streamlined airframe, Concorde's sleek nose obscured the pilot's view.

  • The solution was a nose cone that lowered to provide better visibility during takeoff

  • and landing.

  • The sheer number of innovations was astounding.

  • But by 1967 Concorde was ready to be unveiled to the public.

  • As Concorde landed, dozens of people telephoned the airport to complain about the noise.

  • For those who live near the runways at Kennedy Airport claim it's just the noiset plane

  • in the world.

  • Zero Zero Two didn't help with matters when it left with the loudest takeoff ever recorded

  • at Tokyo Airport.

  • This magnificent machine is a prime producer of a sound that nobody wants.

  • The sonic boom.

  • So far, 7,000 people have complained.

  • The National Science Foundation of the United States Government has...has indicated that

  • there will be severe environmental damage to the ozone layer...

  • In fact they say the plane is all wrong.

  • Too dare, too small, too dirty, and too noisy.

  • Your biggest customers have...have gone down the drain.

  • No they haven't gone down the drain, they...they've….

  • The Concorde has always seemed to me to be part of particularly French patriotism….

  • If you kill it, what do you put in its place.

  • I do not kill it....It never lived...It never lived.

  • There was no future for Concorde from the beginning.

  • By the early 1970s, Concorde was facing a perfect storm.

  • There were even doubts about whether the plane would make it into service.

  • For one, Concorde's afterburning turbojets were twice as loud on takeoff compared to

  • jetliners of the day And it led to protests around the world.

  • And like all supersonic aircraft, Concorde generated sonic booms.

  • Loud bangs heard by anyone under the supersonic flight path.

  • Public tolerance for sonic booms had clearly been underestimated because one by one, countries

  • started banning supersonic flights over their airspace.

  • Evidence was also mounting that Concorde could damage the environment.

  • If hundreds entered into service...regular high-altitude supersonic flights could destroy

  • the ozone layer.

  • But the biggest challenge facing the program was economics.

  • Concorde had been designed in the 1960s, when jet fuel was just pennies per gallon.

  • But it would enter commercial service in the mid-to-late 1970s, just as the price of oil

  • began to skyrocket.

  • And Concorde burned nearly four times more fuel than even a first generation jetliner,

  • while carrying fewer passengers.

  • The economics made no sense.

  • And by the end of 1973 nearly every airline cancelled their options.

  • Leaving just a tiny handful of orders.

  • Nowhere near the 150 planes the program needed to sell just to break even.

  • All the while, development costs were spiralling out of control.

  • To more than ten times the original estimate by the early 1970s.

  • But with the Concorde treaty, neither France nor Britain could back out of the program

  • without paying the other massive penalties.

  • So with or without orders, the Concorde program would have to push forward.

  • After 14 years of development, Concorde was finally ready to enter service, and on January

  • 21, 1976, two Concordes simultaneously lifted off carrying their first passengers.

  • It was a huge milestone for the program, but hardly the bold new era of mass supersonic

  • air travel that many had once predicted.

  • Because British Airways and Air France were the only airlines to put Concordes into service.

  • And both nationally owned airlines had been more or less been forced to.

  • Each taking delivery of just a few planes.

  • With limited range and over land flight restrictions, there were few route options available.

  • Every time Concorde takes off, British Airways loses money, if it's half empty as it is

  • on the Bahrain route, it's costing them up to twenty thousand Pounds a flight...

  • In just the first few years, British Airways and Air France lost tens of millions operating

  • Concordes….

  • And by 1980….rumors were swirling that planes would be retired early.

  • It might seem a strange decision to have the government subsidizing one of the most expensive

  • forms of transport in the world.

  • But a dramatic turnaround was just around the corner.

  • By the mid-1980s, British Airways and Air France were not only still operating their

  • Concordes, they had figured out how to make huge profits with them.

  • With the prospect of supersonic air travel for the masses having come and gone, and with

  • only fourteen Concordes in service, the plane was transformed into more than just faster

  • air travel.

  • Instead, Concorde was rebranded into an ultra exclusive travel experience.

  • Aimed at a new kind of passengerwith much deeper pockets.

  • By the mid-1980s, the price of Concorde tickets had doubled from they were in the 1970s.

  • At one point costing upwards of 20,000 in today's dollars for a London to New York

  • round trip.

  • Concorde might've failed to revolutionize air travel, but it also opened up a profitable

  • new market serving celebrities and the ultra-rich.

  • And with only a handful of aircraft in service, public concern over the environment and noise

  • faded.

  • Instead for nearly three decades, Concorde served as a symbol of pride for

  • the British and French.

  • But much like it's development and introduction, Concorde's final years would prove difficult.

  • A tragic crash in July 2000, caused by a piece of runway debris, tarnished Concorde's impeccable

  • safety record.

  • A year later the events of September the 11th led to a huge decline in air travel.

  • And then there were the challenges of maintaining such complex and aging planes.

  • In 2003, after 27 years of service, the most recognizable and iconic aircraft in history

  • was retired by Air France and British Airways.

  • Closing the final chapter on the most ambitious aviation project of the century.

  • There's a lot more to Concorde's story.

  • win over skeptical airlines and fascinating plans for a second-generation Concorde that
