Mythbusters didn't hear any sonic boom when 3 fighters were flying something like 5 kilometers high, and this concorde is flying 15-30 kilometers away and that sound is fucking loud. It's quite hard to believe this video...
@ERK77VI No, it really did sound very loud, I remember my uncle telling me when he heard it. Usually they waited till they were over the ocean to go past the sound barrier, for that reason. You also used to hear two bangs when the shuttle returned as it went subsonic, one from the nose and one from the tail.
@p51chkt Ok i believe you since that makes sense, but still they had 3 fighters and didn't hear almost anything... Wasn't concorde normally travelling super sonic? It would had make lot of noice when doing comercial flights and i think they had taken that in mind when they build it. Image few hundreds concordes flying around world making that kind of noice.
@ERK77VI Yes, in fact, during Concorde's life, there were thousands of complaints of noise and even property damage. The space shuttle would also produce loud twin sonic booms during reentry even when it was still 90,000 ft up. You can find some videos if you type in those key words.
@ERK77VI No, it wasnt accident or design fault which stopped it from becoming popular, but simply the fact that it ate so much fuel when compared to pax number that it was not very economical to operate it.
@ERK77VI I cant get your video showing up... it just puts me to youtube front page.
Anyway Concorde flew many years after crash before they were retired because they were not economical to operate. Of course they did have their own problems such as easily exploding tires, but that problem did stay for tens of years and they were not grounded because of that.
@Pvjinflight They were just too old. The Concorde was designed in 1960's and it retired in 2003. More than 30 years in service compared to world developing much faster, it just was too expensive to operate. It is sad that there is no replacement for the Concorde and probably will not be for a decades to come.
@kofinp Not at all. I asserted that the speed of sound (Mach 1) occurs at a slower true airspeed cooler temperatures (higher altitudes) than at sea level.
Hence my statement that an aircraft traveling at Mach 1 at Sea Level (+15 C in an ISA standard atmosphere) would be traveling faster (by approx 88 knots) than an aircraft flying at Mach 1 at 50,000 (-56.5C ISA) is very correct.
Shortest time from A to B is the result of highest Ground Speed (True Airspeed + or - wind component).
@kofinp Mach 1 would only represent moving at the local speed of sound. The speed that sound actually moves, however, would vary depending on temperature. The only time that Mach 1 would be the same speed (in mph, knots, kph, etc) would be if the same temperature existed at both altitudes. I'm sure it is possible that it could be a very cold day at Sea Level with a temp of -40C and a very "warm" day at 50,000 feet of -40C. Under these conditions, then Mach 1 at both altitudes would equal 685 mph
@ACfireandiceDC Read my previous comments. Altitude/pressure has NOTHING to do with the speed of sound in the atmosphere. Temperature is the ONLY determining factor for a particular substance, such as air. Google says 761mph is Mach 1 at sea level only because in an ISA "Standard Atmosphere" the temperature at sea level is "assumed" to be +15C. If it were minus 40C at sea level (or any other altitude), Mach 1 would be 685mph.
I flew aboard Air France Concorde several times In 2003,a few months before Concorde stopped flying.Flying to Paris, we flew at 66000 feet at the edge of space. It was awesome!!! I told the captain I felt like John Glenn & he told me everytime he flew Concorde so did he. Thre hours & 29 minutes of champagne,Caviar, great food & wine. I'll never forget the experience. We flew. at the edge of space. You can't top that!

@deep6phil You have never been flying at 66,000 ft with the concorde since the max certified CRZ for the concorde in commersial traffic was 60,000 ft... at test flights they have been up to 69,000 ft... But Maximum certified CRZ for the concorde in commersial traffic is/was 60,000 ft :D

Getting email requests for information, here is a good starting video that explains some of the questions that are being asked, also has some spectacular aircraft footage:
Bloody buggering hell that's loud, is it much louder than it would be for a fighter jet because Concorde is so much bigger or is it always that loud from the ground?
Proper terms are sub sonic, trans sonic, and super sonic and are usually written as one word each with sonic meaning the speed of sound. It is not a constant, but changes with altitude/pressure. Higher at high altitude.
@MrJdsenior Not correct. The speed of sound is dependent only upon temperature. As temperature decreases with altitude, so will the speed of sound. Therefore, an aircraft traveling at Mach 1 at 50,000 ft will be moving slower than an aircraft traveling at Mach 1 at sea level.
Yes, in gasses other than air, helium for example, mach is faster, for sodium hexaflouride slower.
In solids the there are two modes, compressive and transverse waves, and they travel at different speeds, I think. Hope I don't blow it shooting from the hip again. I NEVER learn ;-).
@MrJdsenior are you talking about shock waves? hey, how fast is the sound in a metal, like gold, or steal? i now that the sound trables at 1224 km/h, but i heard that it is even faster in metals and that the speed depends of the temterature, right?
The speed of sound is much faster in water than in air for instance.
The concorde in the video did not just fly through the sound barrier when they heard the bang. It may have been travelling ALREADY at supersonic speed for HOURS.
A supersonic aircraft makes a sonic boom the WHOLE TIME it is travelling supersonic like a speedboat leaving a wake.
Wherever the waves reach the river bank/ground a splash/boom will be heard.
@GregOrca thanks for the info, you really know about this, it is very inresting. hey, another thing, have you seen the car that people says that travels at speed of sound, is that true or it i just a fast car but people exagerated?
CRAP! Mr Hanlon (I assume) is absolutely correct. Been too long since physics and fluids to shoot from the hip, I guess. Very sorry for the missinformation. Turns out that the speed of sound is about 0.68 times the fastest molecular speed in air, which is driven by temperature. Humidity also is a very minor driver. This makes the term"speed of sound at sea level" actually somewhat of a misnomer, since pressure isn't the driver and the temperature is not specified unless by STP.
@kjhanlon Please stop spreading misinformation. This is a flat out lie, and you don't know what you're talking about. The speed of sound is given by a=sqrt(rho*R*T) where rho is the heat capacity ratio, R is the universal gas constant, and T is the absolute temperature given in degrees Kelvin. For more information, google "Speed of Sound - NASA" and go to Nasa's page on it.
@jnino92 I don't disagree with your description but Kelvin, though equal in magnitude to degress Celsius is a unit in it's own right and are not "degrees".
@HuskyMaxx The main reason for the coolness of air at altitude is the distance from the source of heat, viz the ground (air is not heated by the sun) but warm are pushed up by cold air experiences adiabatic cooling which you can feel when you use an aerosol can. When a gas pressure reduces it experiences cooling without any heat transfer
@kjhanlon Incorrect, it's also dependent on air density, although air density is closely related to temperature un the atmosphere. If you think about it a sound wave is a wave carried by air molecules and hence the density of air molecules in a given space will inevitably have an impact on the speed the wave can travel through that space.
@wahaya2 In an "ideal gas" (such as air), the effects of pressure and density cancel each other out, leaving only temperature as the determining factor for the speed of sound.
@kjhanlon you're wrong, the speed of an airplane is the same at any height, the only difference is that the greater height less resistecia air and use less power to go at the same speed at sea level, the more close to the sea, but admosferica pressure will exist so there is air, the greater the resistance.
Actually the speed of sound has more to do with the density of the medium rather than the temperature. That is why sound travels much faster in the water than in the air.
@SanRafaelSwell Indeed, however we are talking about air as the medium, since this relates to Concorde. In AIR, temperature is the only significant factor affecting the speed of sound.
@kjhanlon Not correct. the speed of sound is dependent not only on temperature but density as well, at 50,000ft the air is less dense therefore the thin density would cancel out the temperature equation.
@mad4diesel Not true. In an ISA Standard Atmosphere, the temperature is +15C at Sea Level, decreasing approx 2C/1,000' to -56.5C at and above 36,000' (until 80,000'). The speed of sound likewise decreases from 661 knots at +15C to 573 knots at -56.5C.
Therefore, the speed of sound will be the same at 36,000' and 70,000' provided that the temperature is the same.
NASA's Glenn Research Center website has an atmosphere simulator which will confirm this.
@kwmkc13 you can't hear the sonic boom inside the plane. it comes from the shock waves the plane makes as it moves through the air, faster than the air can naturally "get out of the way". these shock waves move away from the plane.
@Supplementreviewdude yes, the plane will be long gone before you hear the noise of the engines, the plane and space around it will be silent when it goes by, and then a few seconds later youll actually hear the engines
Surely, you wouldn't hear the sonic boom with the plane at that altitutde? Also, how can anyone know that's concorde? It could be any supersonic plane - military.
@250Trojan A lot of the pressure differential depends on the shape and size of the aircraft. The concorde was well capable of delivering a good boom at 30,000ft.
@250Trojan The sonic boom from the concorde can be heard from the ground :) Which is why the Concorde usually broke the speed of sound over water go comply with noise regulations.
Haha, you losers correcting @RANDOMZDUKE the fact he knows what an MD-88 is must show that he's joking. Why on earth would a human being with the ability to at least TYPE think a de-icer would make such noise...
Still guess you got a kick out of flaunting your superior aviation knowledge.
The aircraft is not BREAKING the sound barrier it is already supersonic. What you are hearing are the dual shock waves that come off an aircraft at supersonic speeds. Technically there is no sound barrier.
@lindo745 People know there is no literal barrier. 'Breaking the sound barrier' is a common way of refering to the point where the aircraft passes the speed of sound, you know that too. You're just being nerdy.
@2491cc No, many people don't. Most people don't know what it means to go supersonic. Most have no idea how an aircraft flies. Go in the street and ask some random folks.
What the fuck is wrong with "being nerdy". I guess, and I'm only guessing here, that your one of those folks that dislikes intelligent, educated and knowable people or is intimidated by same.
@lindo745 I have nothing against intelligence. Most people who watch this video simply want to see concorde going faster than the speed of sound and hearing the boom. I don't think they care about the scientific aspect of going supersonic.
Is knowledge being nerdy? I think not. Just because somebody wants to know a bit more detail and share it with others is great... don't be afraid of learning a thing or two.
@TheLondonForever No it isn't. But you're just being cocky, and know that it's a common way of referring to passing the speed of sound. Even pilots refer to it as 'breaking the sound barrier'.
Yes and no, sound is spreading at all directions from the source, since the concorde is moving forward the soundwaves stack behind it and are in fact creating a wave/barrier, when crossing the velocity of sound they stack up and create at explosivelike boom. in conclusion, there is no barrier, but the plane itself creates it, kind of!=)
Well, I did read up and that´s pretty much what it said...you only get the boom when goin from transonic speed to supersonic speed:
"In aerodynamics, the sound barrier usually refers to the point at which an aircraft moves from transonic to supersonic speed. The term came into use during World War II when a number of aircraft started to encounter the effects of compressibility."
@ultram4 ".you only get the boom when goin from transonic speed to supersonic speed:"
Incorrect!
The boom you hear is constant. It is a result of the double shock wave trailing an aircraft at super sonic speed. The double boom you hear is that shock wave as it passes you. Hence the boom everyone hears along the aircraft's flight path as it travels faster then sound. It does NOT only happen when the aircraft goes supersonic.
@ultram4 Awesome information you gave there. And you are spot on in your explination on what really causes the sonic boom when a plane becomes faster then the speed of sound.
I remember when I was a kid and we'd hear the sound barrier being broken regularly. New regulations put a stop to that happening over land areas.

@jnino92 I don't disagree with your description but Kelvin, though equal in magnitude to degress Celsius is a unit in it's own right and are not "degrees".

@kjhanlon Density of the air. Think of constant temp at varied density.
Why is the air cooler at higher altitudes?
HuskyMaxx 3 months ago
@HuskyMaxx The main reason for the coolness of air at altitude is the distance from the source of heat, viz the ground (air is not heated by the sun) but warm are pushed up by cold air experiences adiabatic cooling which you can feel when you use an aerosol can. When a gas pressure reduces it experiences cooling without any heat transfer
Climaticsman 2 months ago
@kjhanlon Incorrect, it's also dependent on air density, although air density is closely related to temperature un the atmosphere. If you think about it a sound wave is a wave carried by air molecules and hence the density of air molecules in a given space will inevitably have an impact on the speed the wave can travel through that space.
wahaya2 2 months ago
@wahaya2 In an "ideal gas" (such as air), the effects of pressure and density cancel each other out, leaving only temperature as the determining factor for the speed of sound.
kjhanlon 2 months ago
@kjhanlon you're wrong, the speed of an airplane is the same at any height, the only difference is that the greater height less resistecia air and use less power to go at the same speed at sea level, the more close to the sea, but admosferica pressure will exist so there is air, the greater the resistance.

@Checozapopan "the speed of an airplane is the same at any height" ???? What are you talking about?
Do you think that Concorde could go Mach 2 at Sea Level? That's over 1300 knots! (assuming a standard 15'C temperature)
You're basically correct about the reduced drag at altitude, but that has nothing to do with our discussion about what affects the speed of sound.
kjhanlon 2 months ago
@kjhanlon
Actually the speed of sound has more to do with the density of the medium rather than the temperature. That is why sound travels much faster in the water than in the air.
SanRafaelSwell 2 months ago
@SanRafaelSwell Indeed, however we are talking about air as the medium, since this relates to Concorde. In AIR, temperature is the only significant factor affecting the speed of sound.
kjhanlon 2 months ago
@kjhanlon Not correct. the speed of sound is dependent not only on temperature but density as well, at 50,000ft the air is less dense therefore the thin density would cancel out the temperature equation.
mad4diesel 1 month ago
@mad4diesel Not true. In an ISA Standard Atmosphere, the temperature is +15C at Sea Level, decreasing approx 2C/1,000' to -56.5C at and above 36,000' (until 80,000'). The speed of sound likewise decreases from 661 knots at +15C to 573 knots at -56.5C.
Therefore, the speed of sound will be the same at 36,000' and 70,000' provided that the temperature is the same.
NASA's Glenn Research Center website has an atmosphere simulator which will confirm this.
kjhanlon 1 month ago
@mad4diesel
the equation for the speed of sound is a=sqrt(γRT) , so you can see that the speed of sound, a, is a function of temperature

@kwmkc13 you can't hear the sonic boom inside the plane. it comes from the shock waves the plane makes as it moves through the air, faster than the air can naturally "get out of the way". these shock waves move away from the plane.

Surely, you wouldn't hear the sonic boom with the plane at that altitutde? Also, how can anyone know that's concorde? It could be any supersonic plane - military.
250Trojan 5 months ago
@250Trojan A lot of the pressure differential depends on the shape and size of the aircraft. The concorde was well capable of delivering a good boom at 30,000ft.

The aircraft is not BREAKING the sound barrier it is already supersonic. What you are hearing are the dual shock waves that come off an aircraft at supersonic speeds. Technically there is no sound barrier.

@2491cc No, many people don't. Most people don't know what it means to go supersonic. Most have no idea how an aircraft flies. Go in the street and ask some random folks.
What the fuck is wrong with "being nerdy". I guess, and I'm only guessing here, that your one of those folks that dislikes intelligent, educated and knowable people or is intimidated by same.

@lindo745 I have nothing against intelligence. Most people who watch this video simply want to see concorde going faster than the speed of sound and hearing the boom. I don't think they care about the scientific aspect of going supersonic.

2491cc 5 months ago
@lindo745
Yes and no, sound is spreading at all directions from the source, since the concorde is moving forward the soundwaves stack behind it and are in fact creating a wave/barrier, when crossing the velocity of sound they stack up and create at explosivelike boom. in conclusion, there is no barrier, but the plane itself creates it, kind of!=)

lindo745 4 months ago
@lindo745
Well, I did read up and that´s pretty much what it said...you only get the boom when goin from transonic speed to supersonic speed:
"In aerodynamics, the sound barrier usually refers to the point at which an aircraft moves from transonic to supersonic speed. The term came into use during World War II when a number of aircraft started to encounter the effects of compressibility."
ultram4 4 months ago
This has been flagged as spam show
@ultram4 ".you only get the boom when goin from transonic speed to supersonic speed:"
Incorrect!
The boom you hear is constant. It is a result of the double shock wave trailing an aircraft at super sonic speed. The double boom you hear is that shock wave as it passes you. Hence the boom everyone hears along the aircraft's flight path as it travels faster then sound. It does NOT only happen when the aircraft goes supersonic.
lindo745 4 months ago
@lindo745 Continued.
That is why you hear the aircraft after the boom. all the sound is behind those shock waves.
Back to school.
