(CNN) -- Last month, a Virgin Atlantic Boeing 787 Dreamliner hitched a ride on a powerful jet stream and flew from Los Angeles to London in a record-setting nine hours and 13 minutes, hitting 801 miles per hour as it flew over Pennsylvania.
Record-setting, perhaps, but for a subsonic airliner.
Half a century ago, the legendary supersonic passenger airliner Concorde made its first test flight, on March 2, 1969. The Concorde 001 prototype took off from Toulouse, piloted by André Turcat, and first went supersonic on October 1.
In 1976 -- over 40 years ago -- elite passengers were crossing the Atlantic in under three and a half hours, flying at twice the speed of sound in the Anglo-French Concorde.
Only 20 of the sleek, delta-winged SSTs were built, and just 14 were delivered to two airlines -- seven each to Air France and British Airways.
With superlative service and cuisine, exclusive airport lounges and stratospherically high airfares, Concorde passengers flew far above other flights, and cruised faster than fighter jets to their destinations .
But what was it really like to rub shoulders with the rich and famous on a Concorde flight? CNN Travel asked some former passengers what it was like to fly on one.
"The flight attendants loved being on it; the passengers loved being on it," says CNN's Richard Quest, who flew Concorde five times. "You were aware of being part of a very small group of people that were privileged enough to be on Concorde.
"Concorde was extremely small, only about 100 seats. It had more like office chairs, bucket seats, and very small windows. It was noisy, extremely noisy, but I challenge anybody not to have a smile from ear to ear when they got on it."
With an interior fuselage width of about eight and a half feet (2.63 meters), Concorde's cabin was just wider than that of today's Bombardier Regional Jet. The SST had a single aisle, with a two-two seating configuration.
"The actual layout of the plane was in two sections. There was a front section, then a middle lavatory, and then a rear section," explains Quest.
"The two sections were identical -- not like one was First Class and one was Business. But there was always a status symbol to being in the front section."
Decant before flying
While Concorde had its regulars, including international businessman Fred Finn -- who flew a record-setting 718 times -- any number of novice passengers could be on board for their one-and-only supersonic experience.
Like Su Marshall, a globe-trotting Canadian who was treated to an Air France flight from New York to Paris by her then-boyfriend, "who had more money than Midas."
In the Concorde lounge at JFK, where the "Air France staff oozed élan," Marshall chatted with an elegant French woman, and admitted that it was her first flight on the SST.
"She was a Concorde regular, and whispered candidly to me, 'You better go to the washroom now. It is impossible to pee once in the air. Too small,'" said Su.
"For a girl used to flying steerage, once through the doors of the sleek, tiny, cigar tube into the body of Concorde, I knew I had entered into the rarified air of gods and kings. But dang, things were small and cramped. Leather, polish and flutes of never-ending Champagne, but really squished.
"But hey, three and a half hours to Paris? I sucked it up," chuckles Marshall.
In the 1980s, Richard Ford was on the team at Landor Associates charged with updating Concorde's interior for British Airways.
"As a part of the detailed technical work it was important to learn more about the flying experience. I was privileged to be offered the chance to make a return flight to New York from London in one day!" says Ford.
"Despite its small size it felt more like an executive jet than a commercial airliner, with thrilling performance," he adds.
"The quality and style of food service was exceptional, and I left with a signed certificate as evidence of my flight."
To meet with an important client some years later, Ford flew Concorde one more time, but as a fare-paying passenger.
"I felt more strongly that I had entered a private club. It was a brief glimpse into a life I had not known, polite, considerate, and beautifully detailed. It was impossible to not feel spoiled, and valued," says Ford.
Concorde was developed at a time when the aviation industry was focused on supersonic airline travel.
In the early 1960s, aeronautical engineers didn't have today's design and analysis tools. But Concorde's designers came up with a remarkably advanced and unique aircraft.
Concorde was the first -- and still only -- passenger aircraft that had turbojet engines with afterburners. Called "reheat" by the British, raw fuel was introduced into the exhaust of the plane's four engines, immediately increasing the engines' thrust by almost 20%.
"Concorde was vastly different from subsonic aircraft at the time. It had no flaps or slats (high-lift devices on the wing) and always used full power with reheat for takeoff," explains former British Airways Concorde captain John Tye.
"Each takeoff was a phenomenal experience, the performance such that we had to warn the passengers in advance what to expect. The roar of the Rolls-Royce Olympus engines, combined with being pushed back into your seat, was like no other civilian aeroplane."
Reheat was also used to push the plane from subsonic to supersonic speeds.
Cruising at Mach 2 -- or 1,350 mph -- at 60,000 feet, Concorde flew five miles above and 800 mph faster than the subsonic 747s plodding across the Atlantic.
The radio chatter between aircraft could get interesting, according to Tye. "We would often warn these slower aircraft we were coming past in case the sonic boom alarmed them, as we shot past faster than a rifle bullet."
End of an era
By 1976, social pressure over concerns with the plane's noise and sonic boom led to the cancellation of virtually all orders for Concorde, leaving British Airways and Air France as the only airlines to fly the SST.
The plane suffered its only accident in July 2000 when an Air France Concorde crashed just after takeoff from Paris, killing all 109 people on board and four on the ground.
Concorde returned to service in November 2001, but age, and increasing operating and overhaul costs, caught up with the planes after almost 30 years in the air.
Richard Quest flew on the final, celebrity-studded British Airways Concorde flight in October 2003.
Of that flight, Quest says: "It didn't matter how famous you were, the star was the plane."
While Concorde no longer takes to the skies, it can be visited at a number of aviation museums around the world. Here are some of the best:
Aerospace Bristol (UK) -- A hugely enjoyable new museum built around the Alpha Foxtrot, the last Concorde ever to fly. The museum, close to the aircraft factory where Concorde was developed, explores the UK's aviation industry. (Hayes Way, Patchway, Bristol BS34 5BZ; +44 117 931 5315)
Museum Air and Space Paris Le Bourget (France) -- Stellar aeronautical museum near Paris that covers the history of manned flight from wooden planes to space rockets and contains two Concordes, including the first ever to take flight. (Aéroport de Paris-Le Bourget, 93350 Le Bourget; +33 1 49 92 70 00)
Intrepid Sea, Air & Space Museum (New York) -- Leviathans of air, sea and space come together at this destination museum overlooking the Hudson River. British Airways Concorde Alpha Delta joins a roster that includes Space Shuttle Enterprise, aircraft carrier Intrepid and submarine Growler. (Pier 86, W 46th St & 12th Ave, New York; +01 212-245-0072)
Auto & Technik Museum Sinsheim (Germany) -- Marvels of motor engineering through the ages are the focus of this crammed museum near Frankfurt. The Concorde takes pride of place with one of the other pinnacles of recent transport history -- a Delorean DMC-12 .
The Museum of Flight (Seattle) -- Billing itself as the largest independent, non-profit air and space museum in the world, the Museum of Flight is home to British Airways Concorde Alpha Golf, as well as the first ever Boeing 747. (9404 E. Marginal Way, Seattle, WA 98108; 206-764-5700).
