Could be wrong, but it think that's caused by the jet moving fast enough to create a vacuum behind it holding in the exhaust.
Or it could just be magic princess power! Who knows.
@TheGoogler, I think that happens when they break the sound barrier.
@El Batman, orrrrrrr... and stick with me here...
Magic princess powers.
@TheGoogler, son of a bïtch....you're right.
@El Batman, it only makes sense!
@TheGoogler, its a Sonic boom. It happens when you go faster than sound. It happens because the sound waves have to cross over one another. It's kinda confusing.
@Gruncle Stan, orrrrrr magic princess powers.
@Lellow0079, magic princess powers explain everything!
@El Batman, no this is what happens when you peak under a plane's skirt
@TheGoogler, you idiot, how could you even suggest such a stupid thing? How would you even get a vacuum up there, let alone empty the bag like that? The cockpit is sealed, you'd just be filling it full of nasty dust.
Just stick to science. Magic princess power has been the most reliable means of flight since the first pigs discovered it.
For the actual idiots out there, this comment is known as 'being facetious.' It's when you imply something obvious to intelligent beings by stating the opposite with clearly fallacious premises.
@Gruncle Stan, if your autocorrect capitalizes "sonic", you play too many games
@TheGoogler, you just made my day, thank you really, i don't remember laughing so hard in a long Time, your comments, one is better than the other!
@TheGoogler, these answers are mostly wrong. It's not from breaking the sound barrier, as you cannot 'see' sound. Read the Wikipedia article on vapor cones to get an idea. While hitting Mach 1 (breaking the sound barrier) is a part of it, that alone is not why this happens, and is actually entirely unrelated, and not a requirement for the vapor cone.
@TheGoogler, So you're partially correct, this is called a shock wave which is not necessarily the same thing as a sonic boom. A shock wave occurs (be it a direct shock or an oblique shock wave) when a solid object goes faster than Mach 1, whatever Mach 1 may be in the medium in which you're traveling. Since this is standard air you can assume Mach 1 to be the speed of sound as we know it. That mist effect you're seeing actually happens because when you're traveling that fast in the proper area of temperature and pressure air, the air will create friction around the body of the aircraft, and sometimes this is enough heat to create mist from the water in the air.
@Gadget, and Spilled Milk is right, it's called a vapor cone, and it's really more of a thermodynamics/air pressure, density problem than it is a real speed thing.
@Gadget, thank you. This effect is possible at speeds well below Mach 1. At higher relative humidity levels this is possible at very slow plane speeds.
@TheGoogler, I read all the replies, but I think it would be best if we went with magic princess powers.
@TheGoogler, MPP FTW!!
I feel pretty, oh so pretty...
OMW to my quinceanera
Its called a vapor cone the sonic booms(constantly breaking the sound barrier) create an area of low pressure and temperature allowing water vapor to condense in the cone shape.
when youre trying to get away from your fart
I'm a pretty motherfųcking princess, bıtch
If a plane wore a skirt would it where it like this...?
I'M LATE FOR THE BALL!!!
When she says her parents aren’t home
Mary fvckin poppins y'all
And whoever identifies as an Apache Attack Helicopter is turn on from looking up a jets skirt.
@The Xenocide, is that a 500 lb bomb or are you just happy to see me?
What kind of hummingbird is this?
