Flight 4590 Didn't Kill the Concorde; Costs Did
pigrabbitbear writes "If the plane were around today — which some still fantasize about — it'd be like powering a stretch Hummer with dolphin blood. The airlines couldn't sell enough tickets on the small plane to even make up for the amount of fuel it needed to guzzle on its journeys, let alone cover maintenance for the technological marvel. (A Concorde's taxi to the end of a runway used as much fuel as a 737's flight from London to Amsterdam.) Customers were fine with ordinary travel times for a fraction of the airfare and the plane only took transatlantic journeys, because going over land was too disturbing. Too much noise."
Really? How is this news?
No sig. Move along - nothing to see here.
Total waste of dolphin's blood.

The Concorde was designed in the late 1950s. We have made rather substantial improvements in technology in the past half century that would allow an aircraft designed today to achieve substantially better fuel efficiency, not to mention the additional efficiencies we can gain via higher altitudes. The stigma of its failure will probably prevent anybody from trying again any time soon, but just because an aircraft designed in the 1950s wasn't cost effective doesn't mean an aircraft designed in the 2010s couldn't be.
You cannot help but wonder if the advent of the powerful laptop also helped to expedite the end if the Concorde, starting in the late 90s laptops were powerful enough that you could actually do some serious work(and/or play) on a plane, especially in business class where you had room and an outlet. All of a sudden the few hours you saved by taking the Concorde became comparatively less valuable.

Tyre explosions and damage were quite common, due to the high takeoff and landing speed of the plane, and the unfortunately placed landing gear location in the wing. Pieces of tyre would damage the wing.
The Russians noticed this was a serious problem so they completely redesigned their Tu-144 and relocated the wheel wells in the engine nacelles. The engines were much harder to damage because of all the titanium, so a tire explosion wouldn't cause a disastrous failure.
But the Concorde doen't travel at "normal cruising speed". That's for proles. It travels at Mach 2.04.
Let's get one thing straight. It's customary to refer to Concorde as "Concorde." Not "the Concorde", just "Concorde."
Carry on.

Your ideas are intriguing to me, and I wish to subscribe to your newsletter.
The vast majority of business meetings are now held virtually anyhow -- networked computers, adobe connect, PCanywhere, yadda yadda, a zillion software solutions now exist so that people with laptops just activate the built-in webcam and boom, they are part of a meeting taking place in no particular location.
Less people need to fly overnight now to shake hands and sign documents. FEDEX and the internet have changed the way we do business.
That said, I used to live a few miles from JFK airport in Queens, and loved to watch it fly in. It came in VERY regular times, it could never be in a holding pattern, so, at 8:15 exactly it would be flying over your head.
Standing on Hook Creek blvd in Rosedale, you'd see it come in at a high angle of attack, with the nose pointed down and the landing gear extended, it looked like some kind of bird of prey about to swoop down and grab a rodent off the ground.

Stop that right now. The "Too noisy" meme was started by Boeing to hurt sales of the Concorde, and it worked. You're still repeating it to this day.
A Concorde going overhead at around 1000 feet and normal cruising speed is no more noisy than a normal jet. It's the afterburners that are loud (REALLY VERY LOUD) and those are only used at take-off.
Too noisy was not just a Boeing claim. Early flights were not required to decelerate below mach 1 before reaching land and they sent sonic booms up and down the coast.
Sonic booms cover wide areas. Sitting 40 miles outside of Seattle one day I heard two large booms, and thought it was near by blasting. It turns out it was two F15s scrambling supersonic out of Portland when a small plane wandered into Air Force One's exclusion zone. Such booms leave a trail of 911 calls.
Eventually, every single Concorde route required subsonic descents and approaches for this very reason. For the same reason no country let them fly to interior airports except France and Britain.
The afterburners (reheat they called it) were turned off after getting off the runway before they hit the noise abatement zone.
With sufficient runway, they didn't need the afterburners at all except to break through Mach 1.
Sig Battery depleted. Reverting to safe mode.
According to TFA, they didn't go to supersonic speeds until after they were over the ocean.
Your ignorance of the flight regimes of the Concorde are astounding. Remember, it flew at Mach 2 (and very quite inside the cabin, as I can confirm as a passenger), and that produces "sonic boom" across the landscape; over water there are few people, so little source of complaints. Sure, the Concorde "is nor more noisy than a normal jet..." only if you consider the XB-70 the exemplar of a "normal jet."
The article has all sorts of inaccuracies and key omissions. Concorde was always fuel inefficient and it was recognized as such in the 70s. It was thought it could still be successful despite this, until wide body jets took away much of its market. Because of its limited success, and limited money at the time, a slightly improved concorde (with greater range making a lot more transoceanic routes viable and about another 30 seats), or a vastly improved concorde (with about 250 seats), were never built. These might have been more commercially successful than the concorde that was built. Even so, Concorde was profitable as a niche market for British Airways. It was until it was grounded following the Air France crash. You may recall that BA spent a lot of money improving concorde and getting it back into the air (e.g. kevlar lining in the tanks), but then quickly wound the program down. They expected it to be profitable again, and fly for another 20 or 30 years. The problem was 9/11 killed concorde. The reason was it was such a niche that BA's concorde profits depending on a lot of regular fliers who repeatedly flew on it between London & New York - and many of these frequent Concorde fliers worked in the WTC. The treaty between the UK & France meant that unless both agreed Concorde had to be kept flying, so when BA lost interest the French neither had the prestige reasons or the monetary reasons (I don't know if their Concorde operations were profitable) to continue either, and it was mutually agreed to shutdown. Also omitted are some additional locations where Concorde can be visited. There is a Concorde (one of the two British test aircraft) that you can go aboard at the Imperial War Museum in Duxford near Cambridge. By coincidence I was there today, and yes I went aboard this Concorde.
Unfortunately, take-off and landing are the times noise creates the worst impact. Also, I don't think you meant "1000" feet, as a commercial jet does not normally fly that low and certainly wouldn't at supersonic speeds (cruise altitude for the Concorde was closer to 60,000 feet, going supersonic at 1000 feet would be really really stupid: noise, safety, and structural concerns due to higher atmospheric pressure that low would forbid it).

We live in an era where we shy back from the edge achieved in the past. Air transport speeds have stagnated around mach 0.9, the top speed at Indianapolis was recorded more than a decade ago, and the optimistic plan for a return to the moon has three times the development time of the original flight. Between tendencies to ensure that we don't do anything that could fail and to form a bureaucracy to hide behind if it does, this century's progress in the peak of human achievement will far lag that of the last.
"Because Science" is one step from "Because old book". Try "Because of my experiment testing my falsifiable assertion".
Acela faces the same problem most of Amtrak does: it travels far under rated speed for most of the route because it's on freight rail. The only time it's travelling faster than the regular Northeast Regional is certain areas before it enters CT (though both trains outpace free-flowing highway traffic in NJ). The principal improvement in travel time is that it stops only once per state, and I believe has a shorter-than-normal layover in NYC (Northeast Regional stops for a good 45min at NY Penn).
"Because Science" is one step from "Because old book". Try "Because of my experiment testing my falsifiable assertion".
I travel Portland to Sacramento and back once a year. Amtrak station in Portland is a few blocks from work, and the train stops literally in front of my hotel in Sacramento. Convenient, right? Every year I investigate, and every year Amtrak is about three times the cost of a plane ticket, with a journey time around 30 hours vs 43 minutes of flight time. Yeah, go by train...
Oliver's law of assumed responsibility: If you're seen fixing it, you will be blamed for breaking it.
There's at least one video on YouTube of it taking off and setting off car alarms at Heathrow. Night too, so you can see the afterburners.
Given the cruising speed was Mach 2, I suspect at 1,000 feet it was probably a fair bit louder than a regular jet. Briefly. Also given Israel has actually used sonic booms as the basis for a form of psychological warfare, I suspect it would be plenty loud enough to wind people up.
Yeah, I had a sig once; I got bored of it.
Figments of imagination don't produce sonic booms. 's a well known fact.
Oliver's law of assumed responsibility: If you're seen fixing it, you will be blamed for breaking it.
A Concorde's taxi to the end of a runway used as much fuel as a 737's flight from London to Amsterdam.
If that much energy were released over that short a timespan, the airplane wouldn't be there anymore, and neither would the runway.
This must be that "Journalist physics" I keep hearing about, similar in methodology to "Cop math."
Oh, goody, en expert. At normal cruising speed and 1000 you would blow every window and eardrum for 2 miles either side of the flight path. And burn up the airplane in a few minutes. This is a moot point as it won't go normal cruising speed at 1000 feet. .85 over land.
The noise associated with the sonic boom, and the accompanying regulation to prevent it, was well-understood in the 60's. That is indeed what killed any possible market for the Concorde - and every other potential SST including Boeing's own. It was dubious at best even without the subsonic limitations but it was a dead loser from a business standpoint once it had to go Mach
This is hardly a Boeing-generated myth. I am sure that Boeing would encourage someone like Airbus to take up the supersonic challenge again, it would be crippling to Boeing's biggest competitor.
Concorde was a British/French vanity project to make up for their (highly justified) feelings of inferiority to the USSR and the USA during the space race. It was a nice design but it was NEVER EVER going to make any money - a fact that many people knew and pointed out repeatedly before it ever flew.
The article on which the submission was based simply stated it used too much fuel.
This was a quote from another article.
Yes, it used a lot of fuel, however at the time of the accident, the fuel and other costs were handily made up by the ticket prices. Every flight was full as I understand it.
Could concorde substitute in the low-cost carrier role - of course not.
Did it have a profitable (after writing off development costs) buisness going forward - yes, as long as the planes remained in good order.
Was it possible that at some point in the future that they would no longer be able to fill the seats - sure.
For a truly niche service, for the very rich, I question that they wouldn't be able to fill the seats at prices enough to pay all the costs now.
Actually what killed Concord was that we have to be at the airport two hours before the flight and that it takes three hours to get to a transcontinental hub. The terrorists killed rapid transport, they won and we live in a terrified world ruled by health and safety lawyers. Enjoy your cotton wool.
Facts are history now plebs have politics for religion on social media.
My parents' house in northern VA was right under a flight path of Dulles. When the Concorde went overhead during takeoff, it wasn't just REALLY VERY LOUD, it was DAMN REALLY VERY LOUD.
Given the cruising speed was Mach 2, I suspect at 1,000 feet it was probably a fair bit louder than a regular jet.
When I lived in the UK, jets from Heathrow would often fly over my house a few minutes after takeoff. Concorde was the only one I could hear from inside the house, and the usual result was a lot of people stepping out into their garden to watch it go past.
Commercial airplanes use tons (literally) of fuel while taxiing. Idling a jet engine is expensive. And london-amsterdam is about the shortest commercially viable flight possible - only about 200 miles - or to put it in US terms, DC-NYC. So, yes, the concorde guzzled fuel - maybe 5 times what a 737 uses - but its fuel usage was not completely irresponsible - after all, you have to carry most of that fuel at mach 2.2...
A Concorde going overhead at around 1000 feet and normal cruising speed is no more noisy than a normal jet. It's the afterburners that are loud (REALLY VERY LOUD) and those are only used at take-off.
I'm sorry but that's wrong. I live in London and you *knew* when Concorde was flying over. But it was damn cool!
Then a controlled dive could eliminate the need for afterburners completely.
Any sufficiently unpopular but cohesive argument is indistinguishable from trolling.
But combine the two, a supersonic Zeppelin! That's pretty much what UFO seers claim to have often seen, something the size of a football field that goes Mach 5.
Too noisy was not just a Boeing claim. Early flights were not required to decelerate below mach 1 before reaching land and they sent sonic booms up and down the coast.
Then they stopped doing that and they stopped being "too noisy". Calling them "too noisy" today is incorrect.
Eventually, every single Concorde route required subsonic descents and approaches for this very reason.
Uhhh, more like they required subsonic descents and approaches so they could be handled with normal traffic, and to obey federal law that has been around for a very long time. 250 knots below 10,000 feet, and 200 knots below 2500 AGL.
The only exemptions are "approval of the Administrator" (unlikely), and "minimum safe airspeed", which certainly isn't above mach 1 for the SST.
I fail to understand how having meetings can do anything to improve productivity.
Let us suppose,just for a moment, that Concorde flew from New York to Los Angeles-- a route that they were forbidden from due to hysteria over noise. The implication of your comment is that Concorde could easily avoid disturbing the populace between New York and Los Angeles by limiting its flight path to the oceans between New York and Los Angeles-- which do not exit, despite the efforts of Francisco de Ulloa
Comments have context.
They had a basketball team named after them?
Noise wasn't the only issue - it's just the only issue to have survived in the public consciousness.
The other issue was range, or more accurately the lack thereof. Back in the 60's, what the airlines wanted was range and carrying capacity - and attempting to provide that drove the costs of the US supersonic effort through the roof. Boeing especially wanted a piece of the growing trans-Pacific market, and took it very hard when it became clear that no practical supersonic aircraft was every going to be anything but a "small trans-Atlantic taxi". (The last quote come from a retired Boeing engineer I used to know.)
You could hear concorde's shockwave from 60 miles. Given that concorde traveled at 53,000 ft (ten miles), well you do the math.
Even military jets don't normally go supersonic at 1000ft. A clean F15 could go that fast, but in a few minutes it would use up all its fuel.
Yeah, if you want to travel cattle class - which is probably as good as business or (nearly) first class on an airplane.
So on a 'cattle class' train you get a seat that folds down into a bed, TV built in, free champagne, etc?
I should travel by train more often.
If you can make it reasonably pratical, suborbital makes sense for very long range routes (i.e New York to Tokyo). Not only is it much faster, but can potentially use less fuel. Instead of punching a hole in the atmosphere for 20 hours, you need enough fuel for the launch (which would still be a lot) plus a little more for landing. Most of the trip at the edge of space is free.
"Be grateful for what you have. You may never know when you may lose it."
A few companies have designed systems being integrated on Airbus and Boeing narrow-body planes in the next few years for testing http://www.flightglobal.com/news/articles/in-focus-manufacturers-aim-for-electric-taxi-eis-by-2016-368554/. My guess is that the technology for it was too large/heavy up until recently, so it wasn't worth the fuel waste.
Actually what killed Concord was that we have to be at the airport two hours before the flight and that it takes three hours to get to a transcontinental hub. The terrorists killed rapid transport, they won and we live in a terrified world ruled by health and safety lawyers. Enjoy your cotton wool.
Speak for your own little country. I leave home at 05:45, get to the car park at 06:00, security at 06:05, on board at 06:15, wheels up 06:30. And I don't live near a hub either - touch down at LHR at 07:30, time for a shower and breakfast, then on the 08:50 departure to TLV.
That's 2h50 until wheels up at a major airport. A modern concorde with increased range could do LHR-SIN in 4 hours, and immigration's always a breeze. Even with my connecting flight, that's 7h30 from leaving my house to arriving at hotel in Singapore.
The trip today takes twice that. If I lived near Heathrow like most of my colleagues, I could knock 1h30 off that time.
As for price, a ticket on Concorde to JFK was £4k in 2003. Today a ticket in First class on a much slower 747 is £6k.
Concorde stopped because there was no competition -- people will pay £6k to get London to New York, and if F in the 747 is the best way (although the SNN hop may be arguably better), why bother putting on a special plane?
They should have been charging £20k each way in Concorder, revamp the interior to offer 32 seats ("suites"), thrown decent wifi etc, and sold it as what it was, a fast comfortable way to New York.
By air: 1h 30m in the air, plus be at the airport 1h before departure, plus spend 15m retrieving your luggage. Total time: 2h 45m. Average airfare: $83.60 one-way, according to gofox.com.
By Amtrak: 16h on the train, plus be at the station 30m before departure. Total time: 16h 30m. $145.
So it isn't quite as bad as you claim. But I agree, it's still not a very efficient way to travel.
For fun, let's add another potential option: high speed rail. 3h 45m, $69.40 one-way, and you can use your laptop and cell phone the whole time, and get up and walk around whenever you want, and there's even a restaurant car. Would you ride it?
Any sufficiently unpopular but cohesive argument is indistinguishable from trolling.
High speed is a joke unless they lay new rails owned by the passenger rail company. The basic problem with rail travel in the US today is Amtrak sold almost all the rail lines off to freight companies so now passenger trains sit on sidings waiting for freight to open the rails up.
The problem with new rails is that it is going to cost a lot of money to tear down homes to make a new rail corridor. The existing ones are pretty much full of tracks and other stuff so there is no room for a new set of rails, especially a high speed track.
So we can look forward to high speed rail being put in, say, from Lodi to Modesto but not going anywhere near LA or SanFran. It will be a wonderful proof of concept, but it is never going to have any riders. And putting in a new rail corridor through LA or SanFran suburbs isn't going to happen.
There is plenty of desert. Not to mention that military jet fighters can easily push past Mach 2 and the US has air force bases nearly everywhere.

Yep, Concorde was noisy but in a kind of cool way. I once stayed in the Raddisson Hotel right next to one of Heathrow's runways, and my room overlooked it - a planespotter's ideal room! The windows were astonishing - they totally eliminated all noise from the planes. Except for Concorde, which created a strong vibration and a dull roar on takeoff, where everything else took off in eerie silence.
Concorde's noise seemed out of place among the modern turbofan fleets but that reflects more how far engines have come since the 60s than anything really wrong with Concorde. Compare it to a Boing 707, DC-8 or other contemporary and it wasn't so stand-out noisy. All planes were quite loud back then.
Concorde may not have made much economic sense but it was a cool thing to have actually existed. Today's world is so run by idiot bean-counters that we are never likely to see a thing built "because it can" again. Rather sad, isn't it?
Same in the UK!
The implication of your comment is that Concorde could easily avoid disturbing the populace between New York and Los Angeles by limiting its flight path to the oceans between New York and Los Angeles-- which do not exit,
Sure there is. It's just not the most direct route.
Um, yeah... Moreover, I remember reading somewhere... would have to look for the reference, that modern passenger trains are capable of going a lot faster than they do, except for the condition of existing rails.
Oliver's law of assumed responsibility: If you're seen fixing it, you will be blamed for breaking it.
Then a controlled dive could eliminate the need for afterburners completely.
Because a controlled dive works so well on takeoff. If you do it JUST right, you can achieve Mach about the time the controlled dive passes the six-feet-under mark.
Pity is, you only get to do this once, there is no go-around, and there's not even an in flight meal. On the other hand, you can get by with a one-way pass and the sniveling brat in 5A is going to die nanoseconds before you do. Small justices matter.
Sig for hire.
From the summary: "The airlines couldn't sell enough tickets on the small plane to even make up for the amount of fuel it needed to guzzle on its journeys, let alone cover maintenance for the technological marvel."
With the increasing concentration of wealth, the number of people who could and would pay >5x the former Concorde ticket price (adjusted for inflation) is probably large enough to carry the aircraft operations and maintenance and then some. To such a target market, a small number of passengers per flight is not a negative at all - it's exclusivity writ large. I think that if the Concorde were flying today, its operators could charge $75K/passenger and fill the aircraft. There isn't any transportation system at present that provides its passengers what the Concorde did: an irresistable combination of speed, luxury, and a conspicuous imprimatur of being the richest of the rich. The market for extreme luxury goods is growing very rapidly, and the Concorde would have fit in perfectly today.
Actually the Concorde had very good range for the type of plane that it was. The engines only needed reheat to bring it to cruise speed, then the reheat was shut off. During that part of the Concorde's flight regime, the Olympus engines were among the most efficient jet engines ever built, even today. All engines have an optimal operating range, and for the Concorde, since it was a supersonic airliner, that was at high altitudes and in the Mach 2 range.
The Concorde didn't even really need reheat to go supersonic, it just needed them to go supersonic in a short enough time to make the flight worthwhile. There is no point taking the Concorde if you are 2/3rds of the way across the atlantic before you hit the speed of sound.
Now as to what killed the plane? In terms of its market, two things mainly:
1) The oil crisis and the cost of fuel.
2) The pollutants were found to be ozone depleting. Now with the number of planes that were eventually made, that really didn't make much of a difference, but if the plane was built in much larger numbers then the environmental impact would have been much more significant.
Now the oil crisis had an impact, the regulatory issue of not being able to go supersonic until the plane was outside the territorial limits of the US and the UK did play a role in that, but that was more of a compounding factor than a critical one.
Once the decision was made to only make the 13 units, and the fixed cost investment was written off by the two governments, the planes were generally profitable. Yes that is accounting tricks because the fixed investment was taken off the books, but from an operational perspective, they weren't a drain on the airlines that operated them.
What forced them to be taken out of service? That was a regulatory thing. The successor manufacturer and the holder of the certificate of air worthiness (airbus) decided not to keep that up to date. So really neither Air France nor British Airways had a choice in the matter. Once the certificate expired, they couldn't fly the plane anymore.
You could hear concorde's shockwave from 60 miles. Given that concorde traveled at 53,000 ft (ten miles), well you do the math.
I grew up in southern RI, just north of the spot where the Concorde went supersonic. Every day during dinner, all the plates would rattle in the cabinets from the shock wave of the 5:00 flight. At that distance the boom wasn't audible, but there was still enough subsonic energy to shake the house.
Stop that right now. The "Too noisy" meme was started by Boeing to[...]
Okay, no. Stop. Repeat after me: NOT EVERY PIECE OF INFORMATION IS A "MEME".
This is in much the same way that not every fucking use of the internet is "the cloud". Stop that right now.
So you're complaining about the Cloud Meme... and the Meme Meme?
William of Ockham had no beard. The most likely explanation is that it was chewed off by squirrels every morning.
What? The sonic boom is generated by the passing of the shockwave from an aircraft flying overhead at supersonic speed. It doesn't just happen once when the aircraft "breaks the sound barrier". The shockwave is produced as long as the aircraft is flying at supersonic speeds. Everywhere that the trailing shock wave passes over will experience the sonic boom.
Have you heard of The Capital Gate in Abu Dhabi?
Now there's something built, Just Because We Can!(tm)
It's the world's "most crooked tower" with it's top floor overhanging the bottom floor by more than 100 feet. It's an astonishing building with a design of little practical value, and a lot of wasted space. It's core was built tilted in the opposite direction of the current tilt, then the shell was built and pulled the core straight leaving a huge 80 story tall atrium in the tower. While a gorgeous building, It's one strange customer.
Hectice, baby, Mercator says hello to you
Pre-September 11 2001, Concorde almost consistently made operating profit on every flight. The aircraft only had to be half full to break even on all costs, INCLUDING FUEL.

Operation Guillotine is in effect.
I only saw Concorde taking off once. I was in the 2nd or 3rd next plane waiting in line on Heathrow to take off. All of a sudden there was a thunderous roar and I thought "that can't be right! We're not even facing the right way yet!" because I thought it was our enginges revving up for take-off.
Then the captain came on the radio (it was a BA flight so he was rightly proud): "Ladies and gentlemen, on your left... Concorde".
And there it thundered past, 4 afterburners flaming, making the most noise I've ever heard from a plane.
So sad I never had the money to get a ticket on it.
Concorde was a British/French vanity project to make up for their (highly justified) feelings of inferiority to the USSR and the USA during the space race.
Vanity project?
Let's see they basically had a mach2 capable bomber design, which they never (AFAIK) tested as a bomber (though they *did* carry out a number of rather strange tests in France which made absolutely no sense for an aircraft intended as passenger transport, but were perfectly understandable in the context of testing out a strategic bomber..and testing out defences against similar such supersonic bombers then in development by a.n.others).
Concorde gave both the French and British military a lot of aircraft stress data, and provided a useful testbed for a number of technologies under the pretext of it being a civilian airframe design.
The reason that they never did anything further overtly militarily with the design?, feh, who knows?, typical French apathy and the usual British incompetence? (and the continued British fawning and kowtowing to the US stopping anything interesting happening here).
A cynic might argue that the main British interest in the continued subsidising and maintaining the use of the aircraft as a SST for so long after it was obviously economically non-viable (and as part of their original spec for the design was to take about 100 people across the Atlantic as fast as possible) was that it meant that they'd still be able to get Queenie and the rest of the Royal parasites across the pond to Canada in the event that WWIII broke out in a somewhat unexpected and exciting manner (height of the cold war, damn'd Russkies, don't trust 'em, never could play the war game like gentlemen..), having a fleet of them meant that some of the parasite politicians/civil servants of the day could also escape to that remote part of Canada with the suitable airstrip...
Then, the accident happened. They re-evaluated, someone spotted that the cold war was over, the inertia to change finally gave way, exit Concorde stage left...and I have to leave the last words on her to PTerry
'It wasn't a thing, it was a bit of shaped sky ...'.
My school was in the noise-abatement area near Heathrow. Naturally it was pretty well soundproofed. You could tell Concorde when it was flying over, but it wasn't much louder than other aircraft were then (they are generally quieter now). One day we heard an almighty roar, so loud that in our soundproofed classrooms we couldn't hear the teacher talk.
One the news later we found out what had happened. At Heathrow aircraft come in to land in a line of three. The plane landing before Concorde had suffered undercarriage damage and was stuck on the runway. Concorde was instructed to perform an emergency fly-over. During a normal take-off and landing Concorde had to throttle down to 30% thrust over the noise-abatement areas. I don't understand why, but something about the trim and positioning of Concorde during descent meant that to pull out of the landing path it had to use full afterburners over our school. Kids who were outside doing sports told me it was awesome, they had to put their hands over their ears because it actually hurt!
Fuck yeah. What's wrong with a bit of noise?
PEOPLE SHOULDN'T COMPLAIN THAT MUCH!!!

Indeed. However, and take this with a grain of salt, they are working on sonic boom suppressed designs, and apparently have made some good progress.
I am John Hurt.
In America, sonic booms were silenced by public complaint. In Soviet Russia, public complaints were silenced by sonic booms.
