[rottencactus28]

wtf is that!?

[kinsley2108]

WOW! Time travel is possible!!!

[ntiffin1]

ha ha ha! good one about the ex wife

[partenavia]

If this exceeds your wingspan and you fly into it, enjoy the unintended roll...

[danm981]

Reminds me of my ex-wife and my money.

[GoofballLtG]

That's quite a wake.

[bluecshield]

Thats not a blackhole thats a Portal instance to a raid dungeon

[Johnny64ism]

Frickin Awesome  !!

[Gh0StSecurity]

omg this is the most clearly way to show me what is a wingtip vortex thanx man! this is so weird :D

[Remington1875]

No CGI here!

[Ilivemindfreak]

HAHAHA C-5A Galaxy = Cloud of Smoke that looks like a Galaxy :D Double FTW or Double PWNED!

[metallicaafeb]

fucking idiots, is impossible that can be a black hole

[Deathstar11978]

@metallicaafeb tit

[metallicaafeb]

@Deathstar11978 pff

[metallicaafeb]

@Deathstar11978 jaj and .. who would come being you? (:

[oggybodoggy]

I can assure you that is a black hole on earth, that is what NAZA does, making black holes around the globe day in day out

[metallicaafeb]

@oggybodoggy idiot

[oggybodoggy]

@metallicaafeb I was trying to be Ironic/Sarcastic, sorry that you didn't understand

[metallicaafeb]

@oggybodoggy (;

[nigelolympia]

You are cleared for take off following a heavy C-5A ,Caution wake turbulence.

[meganite03]

vortex vorTEX!! Not vortice! >_<

[Tundraboy05]

@meganite03 A VORTICE IS A MINI TORNADO.

SO SHUSH.

[meganite03]

@Tundraboy05 The word "vortice" does not exist. Singular: vortex; plural: vortices.

[Tundraboy05]

@meganite03 Oh well, it's used commonly throughout the Tornado-Chasing service, maybe it should be a word.

[meganite03]

@Tundraboy05 likewise, the word "vertice" is used throughout the computer graphics world, though the actual word should be "vertex." Using the correct word will show that you are truly a professional. If you can find a professional published usage or definition of the word "vortice," as being different from the word "vortex" or interchangeable, I will concede the point. Otherwise, I recommend you use the word "vortex" and encourage your Tornado-Chasing colleagues to do the same.

[Exploredia]

Exploredia,com

[bleedinfingers]

If anyone was wondering, they are called wingtip vortices but they are created by the entire wing as a whole, and shed at the tip. You can't create a wing that generates lift and doesn't do this too

[HeliumFreak17]

If it "looked" like a black hole then technically you wouldnt be able to see it .. right?

[1993phillipB]

@ stuartic

xD The plane had a lot of fun in Mi(y)anus xD

[stuartic]

looks like a bruised anus !!!

[robertgift]

Very poor representation.

Why not show UNCUT film of the aircraft going over.

Why not show until dissipation?

[xxcurnuxx]

@robertgift the footage doesn't exist or is extremely hard to find.

[yoshihawv]

HAARP testing?

[yemenarGTR]

That's what comes out my arse after a curry

star gate nigga

[thebig419]

i was lookin for the house and the witch on the broom (ill get u my pretty muhahahah )

[allanafraser]

thats a time tunnel, any fool can see that :P

[DKF22]

damn thats sick!!!!! it looks like a tornado

[CombatRadar]

It's called wake turbulence you idiots...Look it up.

[treborobotacon]

That is exactly what killed Goose in top gun. Bastards!!!

[raven1234]

It just opened a gateway to hell!

[xXRacer9000Xx]

damn thats f***ed up i wonder if that screws up the next plane coming

[FunktasticLucky]

@xXRacer9000Xx Yes it does. When learning to fly you will learn about this type of thing. It's called Wake turbulence and happens from all aircraft. The problem arises with wake turbulence from big aircraft overpowering small aircraft.  I have seen a 737's wake turbulence flip a single engine Cessna. While taking off in a Cessna 172 the controller will clear you

[xXRacer9000Xx]

@FunktasticLucky damn....thats insane....

[FunktasticLucky]

@xXRacer9000Xx Also While taking off in a Cessna 172 after a large aircraft, the controller will clear you for takeoff and tell you caution wake turbulence. This lets you know it might be present. The 172 is much lighter and will come off the ground before the large aircraft. But those large acft will climb at a faster rate. So the small acft would end up flying through his wake turbulence. After yout ake off in the cessna the procedure is to immediately move off to one side to fly around it

[huntercra]

that is cool

[Jameslh605]

DIVIDED BY 0 OH SHI-

[JechtAeon]

Looks like a black hole.

[JBofBrisbane]

It's actually a vortex. The plural is vortices.

[xXning3nXx]

better tell that to nasa. they're the ones who made the video...

[Helicopterpilot16]

Of course if you know aerodynamics, there are two wing tip vortices! No?

Not counting the vortex made by the flap!

[moshi7kimi]

^_^

[sheldordaworrior]

y did it cut from :09 to :11??

wish it was one video

to see how the smoke ended up that way

[crazysunami]

if anyone watches the end of the 2nd die hard movie, they can see a GREAT example of wing vorticies when a plane lands through smoke.

[bazzerpeck25]

true dude .

[Helicopterpilot16]

@crazysunami I've noticed it and its an awsome view of em! Aerodynamics rocks

[snooppupc130jrketmas]

the fast wind of the pane colliding with the still air creates a sideways tornado. is that easy?

[aguirreruru]

??? sooooooooo.......... the black hole was made by the airplane ???

[anonymouslogon6]

This is actually very important to know for pilots. Wing tip vortices have brought down small planes and passenger jets alike.  This is why there are rules governing the distance between planes.

[85kanuto]

It looks like a black hole with some spinning matter around it.

Look at center,it's black (or dark).

[Splooshiba]

i can promise you 100% its not a black hole :P

[85kanuto]

I know it wasn't a real black hole but it looks like a real at 0:22.

The center was black (or dark).

It would be terrible if this would be a real black hole ;-P

[ElRhinoProductions]

yea basicly, we would not be sitting here typing away on youtube right now if that was a black hole =P

[iBizkitas]

@Splooshiba Or mayabe it isss aa ? ;DD

[nataliev83]

it looks like the gateway to hell

[raunchbear]

More like the gateway to Obama

[anonymouslogon6]

You aren't kidding! Whereas wing tip vortices can bring a plane down to the ground, Obamas polices are just as dangerous, since they'll bring down the country!

[zabyjaku]

It looked more like the Oblivion Gate ..hehehe

[Somewin14]

That Look like a tornado twist

[alancoolio]

lol

[IdolHans]

Very old video showing an A model with filthy smoke belching engines (that was fixed). I took part in a vortice study on the drop zone enviroment back in 1987. We mounted smoke generators on the wingtips using the landing lights for the electrical circuit. Did they tests staging out of Davis Monthan (we came out of Travis) and flying around Yuma. Tests ran about 2 weeks. I have video of it and should transfer it to DVD and then YouTube. Thanks. Check out my video of the USAFJill Metzger Scandal!

[7Goggles7]

riveting tale, chap!

[Faucon551237]

Now you understand and SEE how much it's dangerous for a ligh plane O_O

[SteveCessna152]

Do they still do this or do they just do it in the wind tunnel now?

[sk8rguy178]

when designing the airbus A380 they did some testing in a tunnle, they were trying to figure out how to minimize the wake turbulence, and that why it has winglets

[sk8rguy178]

@slaneyboi no the engine cause jetwash the wingtips cause wingtip vortices both create what is known as wake turbulence. the use of winglets reduce lift-induced drag result in a less prominent wingtip vortex. do you even fly? lemme guess your an atp rated fsx pilot

[slaneyboi]

@sk8rguy178 Lmfao, i posted that comment years ago, i was just beginning my PPL. I have done 33 hours now in a Cessna 150, im going for my night flying and instrument rating when i should acheive my PPL, sorry.

[terryk1233]

@slaneyboi

thats funny.

[Hondaridr58]

@slaneyboi sorry dude, it is the wingtips that cause wake turbulence.

[terryk1233]

@slaneyboi

from the engines? and you just called someone out for talking shit? ......i love it

[otoevst]

I thought the vortex went downwards. But here it looks like the turbulence stays in the air.

[thomaskroon]

the vortices will go downwards, but it will take approximately half a minute.. see other videos. the overpressure beneath the wing will compensate for the underpressure on the upper side. to minimize this induced drag, aircraft have wingtips or winglets.

[dem3993]

it does its creates a swirling disturbance as you can see....they move outward from the plane not down

[Chopin742]

They do fall at something like 900 ft. a minute, but it is already at the ground. Once they get to the ground they just move laterally. Check the Far-aim if you're a pilot.

[moopoo23]

Very interesting. Thanks for uploading.

[xregizorx]

looks like a black hole

[desinate]

Now we know what a black hole looks like

[Rocktheworld10x]

@xregizorx You can't see a black hole... ;)

[damienoneillbree]

@xregizorx you can't see black holes

[tusiunia12]

what's that?

[jordanburr74]

Wingtip vortices are caused by the acceleration of the air around the wing. It spirals outward and downward, and will blow a little Cessna right off the runway. Heavy, clean and slow.

[adzmc123]

is that wat a jet stream is?

[jordanburr74]

The jet streams are large moving masses of air between the troposphere and the stratospere that are a lot like rivers in the sky that flow all the way around the world. They move anywhere from 150-300 miles per hour. This is why commercial jets fly in them. A tailwind of 300 miles per hour get you there faster.

[FA22RaiseHell]

Jet stremas not only get airliners to thier destinations faster, it also saves more fuel. I'm just adding from what you had stated.

[Weirdo10o4]

Wake turbulence, I think.

[tubulus3]

Wheeeeeeeeeeeeeeeeee

[jwigiMT]

yeah anyone flies through that shit... you're gonna get rolled

[ChampionServices777]

you mean like this ?

watch?v=Yu_moia-oVI

[spidertron99]

good one. that made my day

[Floatsforlife]

i saw the same thing when i pulled your moms pants down......... the galaxy and a black hole!

[5353LAZ]

crash boing 737/800 amsterdam

If the approaching aircraft if there is another "wake turbulence" What is the rate of the turbulence to produce?

- If an aircraft wake turbulence category is high, in front of the THY plane made up, how many miles of air traffic separation is made between ünitesince? Is it necessary for caution?

[WesselB]

The aircraft preceding THY1951 was a B757. Officialy qualified as a medium aircraft, but ATC regards it as a heavy one because of it's severe wake turbulence.

Minimum separation on landing between a medium (737) preceded by heavy(757) is 2 minutes. Those 2 minutes include a safe margin.

On an airport like Schiphol one can expect that ATC has complied with those minimums, so it would really surprise me if wake turbulence was the reason of 1951's crash..

[atillayayla2456]

this shit is cause of thy 737 crash in amsterdam.

[KERVERAS]

hi...this is just a thought....correct me if i am wrong but this is an example of a lift induced drag that results from the turbulent air of the upper and lower surface of the wing that meet each other and form vortice ?????

[peepeevagi]

So...

What does it help solve exactly?

[kubanpanzer]

it help us visualize why many aircraft have crashed when landing after a heavy jet, and its a powerful reminder not to do it...

[pjm5678]

coolest thing ive ever seen

[darcougar]

that is insane

[amkuc27]

Probably one of the coolest things I've ever seen. Fluids & Aerodynamics is amazing.

[sverio12345]

inside job

[rosepubmuso]

My father used to be a pilot of light aircraft many years ago and one day took his friend up for a flight over the home town. He took off after a large aircraft before him and got caught in the vortex which subsequently flipped his aircraft over. Dad, being an experienced pilot, said that it was very frightening. His friend, who openly admitted to dad that he was a little scared by flying and had to be encouraged for weeks to do it to get over his fear, shit himself. Like, touch cloth style.....

[kubanpanzer]

youre correct dude, Im a pilot myself, they teach you in school to lift off before the point where the heavy jet did it, and try to outclimb it.. yet we know its impossible since a small airplane can never outclimb a jet, so the best thing is to wait at least 3 to 5 min after the fatso took off to give it a try.. I hope I never get the chance to experience what your dad did, I might not survive as he did...

[GeneralKenobiSIYE]

I'd have shit myself too! Only because I probably wouldn't be the one doing the flying. As long as I am in control, I am unafraid. My fate is in my hands kind of thing.

[IloveSPIDERZ]

You can still fly a plane upsidedown though, can't you? Also, How high above the ground was this?

Man, that must have been VERY frightening!

[rosepubmuso]

Yes it's absolutely possible to fly upside down so that wasn't a proplem. It was just that, at 150 feet off the ground, being forced to fly upside down was a little unsettling!

[PR4Y3R]

lol ... freaky

[Yamhal]

THATS AWESOME

[prince0292]

opening a portal to another dimension..... flying into it in a small plane u will fly straight into hell

[xlqex]

I'm not sure about the portal bit. But flying into it will definitely produce some bumpy results!

[DJFiFTY24]

and in a small plane, it can send u right 2 hell

[brettv8]

Or an early 80's Flash Gordon music video with Queen....

[TheJeffreyklm]

@prince0292 It really will, because you crash if you do that! haha.

[prince0292]

a portal to another dimension ...fly into it in a small plane u will fly straight into hell

[grooveclubhouse]

like there opening a portal to another dimension.

[stucollett]

even though it looks like the left wing comes close to the tower the vortex looks like it is rotating the wrong way for the port wing. when vortecies are formed the high pressure air leaks around the wingtip to get to the relatively low pressure above the wing therefore the port vortex should rotate clockwise when viewed from behind not counter clockwise. This footage may be of two separate experiments or it could be highlighting the drift of vortecies though the windsock is pretty limp.

[d1rcwill]

It's rotating the right way for the port wing. Look at some diagrams that show WIG and you'll see.

[NKS969]

PORT is the left side matie.....This rotation is counter clock wise. Therefore it's indicitive of WTV off the STARBOARD (right) wing. Air flow comes out from the bottom of the wing and rotates upward and inboard. A 'PORT' (left) wing tip vortice would be viewed as 'clockwise' from the rear......You dig?

[d1rcwill]

You've got it backwards. Air rises off port wing, moves away from fuse, drops moves inwards, and rises. From the rear this is anticlockwise. So it's the port wing.

[cjracer1000]

Well in America(which most of us on Youtube are from) we call it counter-clockwise.

[d1rcwill]

No-one cares about the word, it's the meaning that matters.

[cjracer1000]

of corse i was just trying to use comic releif

but i just realised it wasn't funny at all :P

[GooseGrl172]

Sorry, but NKS is correct, it's originating from the starboard wing.

[d1rcwill]

Nope. You're still wrong. The air away from fuse above the wing, and towards the fuse under the wing (though by this time it's behind the wing). On the port wing that's anticlockwise (viewed from the rear).

[skipplet]

Sry d1rcwill - you're wrong. The vortex you see in the video comes off the right wing.

[NKS969]

Stucollet, you're correct. I'm not sure HOW d1rcwill is looking at this but he has it backwards. The test tower is off the right (starboard) wing at the time the acft passes by.

[walkandlookup]

interesting would be a C5M with wortec reucing wingtips (winglet or wingtails)

[1ToNJaB]

BLACK HOLE!

[grzesieksz]

lolooolol

[matt420740]

look how close his wing comes to the top of that tower!!!!!

[jmcbrid0]

it only looks close but its not

[BAYCITYROLLERBOY]

Bermuda Triangle weather?

[wildblue2]

Bwah looks so sinister, i love it. I guess is actually is if you're in a small aircraft.

[trahcceb]

So was there a few of these babies flyin around when Dorothy left kansas?

[Gharr4126]

rip the wing right off what i fly thats for sure prolly the rudder too.

[DobeDobyDo]

Thats wild and powerful

[crapper1]

spiral of doom

[vader2502005]

your right. up here in alaska several crashes and severe structural damage has been due to wingtip vortices

[ak49ericeman]

Tim, get off the radio tower! A black hole is coming right for ya! OMG.

[d2kool594]

omg!! it created a black whole!! lol

[golfcharlie232]

Really amazing !

[xxxreapercrossxxx]

dude it looked like a black hole D=

[xXxmidgexXx]

haha circle.

[Crazyalb92]

Thats scary.

[petersm69]

thats cool

[torigolddust]

Awesome! From an artist's point of view, those colors are actually very nice swirled together..now how's that for unscientific for you? lol.

[kingdomboost]

Awesome!

[cmscastejon]

wow!

[sevenboarder]

amazing!

[niflap]

Why did the bottom smoke start rotating first, since the swirling air descended into it from above? Smoke on top should have started swirling upward first & the eye descending through it. THere's a screaching tire on a gravel road.

[SarraPiyopiyo]

I believe that it started at the top, moved down, then hit the ground, compressed, and moved back up.

[niflap]

Best wtv graphics I've seen yet. Looks easily fast enough for a wing suited skydiver to "surf" on.

[shortattentionspan1]

you fly too close you will think you're in a washing machine!
