@hilers72652 that's a scottish F18 and that's a kilt LOL

[warderseeker]

@Rik4100 for ppl who think they know, the cone around the plane does NOT mean it has passed the sound barrier, it means it's approaching it

[DutchHaggis]

@GagneCarter1217 basically water vapour in the air is condensing around the plane as it approaches the sound barrier

@Xypher911 Did you hear it kinda fade into the sound? Well when it hits the sound barrier, it won't be a fade, it will be a sonic boom which is extremely loud. This in an airshow though, so they are not allowed to fly over the speed of sound.

@Xypher911 you would be deaf

[PrivateCustard]

@GagneCarter1217 The cone, known as the Prandtl Glauert singularity, is caused by extreme pressure changes around the aircraft. The air temp lowers due to the pressure change and condensation appears.

@Xypher911 The first giveaway is that you won't hear it until it's passed you. The second is the sonic boom.

You can hear people go oh! They think the plane is failing.

@warderseeker So how do we know if it breaks the sound barrier? Just being curious.

@GagneCarter1217 When an aircraft approaches the sound barrier, certain parts of it go supersonic before others. This gives rise to what is known as a transonic shockwave, which gives rise to the Mach cone as it forms on the aircraft above. Once it is stable - the whole aircraft is supersonic.

[233kosta]

@warderseeker Actually it means the aircraft is transonic, meaning only parts of it break the sound barrier. Without a transonic shockwave, this Mach cone will not form.

Hey god, we got a glitcher over here!
