Why was Concorde so fast?

Concorde used the most powerful pure jet engines flying commercially. The Aircraft's four engines took advantage of what is known as 'reheat' technology, adding fuel to the final stage of the engine, which produced the extra power required for take-off and the transition to supersonic flight.

Flying at this altitude not only helped save on fuel but also helped the jet save significant amounts of time, as at 60,000 feet, there were almost no jets that air traffic control would route Concordes around. The only aircraft flying beside the supersonic transport were either military aircraft or other Concordes.

Indeed, Concorde's technological innovations still awe aviation experts today. British and French engineers designed features for the unique challenges of traveling at supersonic speeds: the aircraft's adjustable droop nose, revamped brake systems, delta-shaped wing and expandable fuselage.

Technical, financial, and regulatory hurdles make a return to the skies extremely unlikely. Concorde is an aircraft that captures the imagination and is instantly recognizable even to non-aviation fanatics.

Fifty years ago, the federal government banned all civilian supersonic flights over land. The rule prohibits non-military aircraft from flying faster than sound so their resulting sonic booms won't startle the public below or concern them about potential property damage.

Such speed didn't come cheap, though: A transatlantic flight required the high-maintenance aircraft to gulp jet fuel at the rate of one ton per seat, and the average round-trip price was $12,000.

Concorde is sadly no longer flying, but it is still possible to visit some of the remaining 18 airframes, there are others not open to the public but you can still see them.

In real life, Diana took several trips aboard the Concorde, both with Prince Charles and solo.

Only 20 Concordes were ever built. The standard return fare from London to New York was £6,636 in 2003. Concorde guzzled a staggering 25,629 litres of fuel per hour. Over one million bottles of champagne have been consumed on Concorde passenger flights.

The aircraft quickly proved itself unquestionably as it reached speeds of up to 1,354 mph. To put that into context, that is around 800 mph faster than a Boeing 747 and over 350 mph faster than the earth spins on its axis!

The cockpit voice recorder (CVR) recorded the last intelligible words in the cockpit (translated into English): Co-pilot: Le Bourget, Le Bourget, Le Bourget. Pilot: Too late (unclear). Control tower: Fire service leader, correction, the Concorde is returning to runway zero nine in the opposite direction.

It was just one minute 17 seconds after its pilot was told the plane was on fire. According to a report by the Mirror, Captain Christian Marty's last words on July 25, 2000, were: Too late... no time. The co-pilot was then heard to say: Le Bourget, Le Bourget.

Despite the crew being trained and certified, no plan existed for the simultaneous failure of two engines on the runway, as it was considered highly unlikely. Aborting the takeoff would have led to a high-speed runway excursion and collapse of the landing gear, which also would have caused the aircraft to crash.

BA never suffered a serious accident with its seven strong fleet. Concorde service was profitable by the late 1980s and if not for the economic downturn and Air France Concorde crash of 2000, may have survived to this day.

The Concorde was famously loud: a take-off at Washington airport in 1977 measured 119.4 decibels. By comparison, a clap of thunder hits 120 decibels while the pain threshold for the human ear is around 110.
