- DaBrainiac, on 10/12/2007, -13/+251Nah, this is the coolest picture I've seen all day (and may ever see): http://i84.photobucket.com/albums/k2/weekendshow/mybuckets.jpg
- inactive, on 10/12/2007, -4/+85I love this one too: http://www.airliners.net/open.file/1197485/M/
- Shwenk, on 10/12/2007, -28/+94THE PLANE IS FARTING LOL
- JohntB, on 10/12/2007, -7/+52The plane's movements cause the pressure behind it to drop, as the air gets out of its way in front of it, and takes a little time to get in back behind it. The pressure drop causes water vapor to condense.
- davidrools, on 10/12/2007, -2/+30the cloud is the result of the low pressure region created as the plan pitches upward really fast while still traveling forward (to the right, in the picture). The low pressure lowers the temperature so vapor condenses out of the air, kind of like it does on the outside of your glass.
and it can happen at speeds well below mach 1. the prandlt-glauert clouds do form in transonic flows but this isnt that. - drocha184, on 10/12/2007, -2/+27YOU WIN!
- borninda818, on 10/12/2007, -6/+31you mean they enhanced the image using Adobe® Photoshop® software?
- inactive, on 10/12/2007, -6/+27"THE PLANE IS FARTING LOL" + 32 diggs
What has Digg come to? - meridianknight, on 10/12/2007, -4/+20Seems to be some confusion as to what's going on in the photo. The photo is of a F-111 banking while doing a dump and burn. The vapor on the wings are due to lift condensation, not the Prandtl-Glauert singularity. The aircraft is banking, and not transonic. A good explaination of the difference is here:

On my last comment, I explain the fire behind the jet as fuel dumped then ignited by the afterburners.

http://en.wikipedia.org/wiki/Fuel_dump_systems#Dump-and-burn - lando3d, on 10/12/2007, -2/+17logic please, it was photoshopped to add the copyright at the bottom
- PatrickSauncy, on 10/12/2007, -1/+15It isn't a flame projector, and it isn't afterburner. The plane is dumping excess fuel and igniting it.
- noisuf, on 10/12/2007, -2/+14Pretty neat, but by far not the coolest picture of the day. I still digg it :)
http://www.airliners.net/open.file?id=1197864&size=L is cooler - chicoer2001, on 10/12/2007, -1/+12What's with all the hyped titles. That wasnt the coolest photo.
- blizzok, on 10/12/2007, -4/+13Cool picture, but the title gets a thumbs down. I hate it when people try to insist something is the COOLEST I WILL SEE ALL DAY or SOMETHING I LIKE or THE COOLEST I HAVE EVER SEEN
leave both me and you out of it. - rubored, on 10/12/2007, -1/+8Australia kicks arse..
- razrielle, on 10/12/2007, -0/+7Hey too bad this is the aussies doing that manuver and not the US millitary. If you look at the photo description in clearly says "More: Australia - Air Force
More: General Dynamics F-111C Aardvark" so please know who your bashing before you do it - bstew22, on 10/12/2007, -1/+8Frost spec is better imo.
- alex4u2nv, on 10/12/2007, -0/+7New titles please!
Almost every day I see a new digg: "Coolest... you'll ever see...," "Hottest... you'll ever see...," etc. - steveoco, on 10/12/2007, -0/+6My dumps are never this impressive
- sTiVo, on 10/12/2007, -4/+10As sad as that would be, you may be right about that...When a jet turns on it's afterburners, it doesn't look like the bottom of the space shuttle.
- adml_shake, on 10/12/2007, -4/+10"Jet cuts one in mid air"
- nelsonen, on 10/12/2007, -0/+5He is going to get kicked out of the academy for practicing the Kolvoord Starburst.
- crash331, on 10/12/2007, -2/+6I don't think anyone said afterburners, they said it was a fuel dump set afire by the afterburners.
- phenolholic, on 10/12/2007, -1/+5thats alot of fuel. i wish the government felt the toll of higher fuel prices as much as its citizens
- tito13kfm, on 10/12/2007, -0/+4Try manual focus, set your aperature as small as you can go while still maintaining a decent shutter speed (1/125 should be fine). This will widen your depth of field while still maintaining that "moment in time" look you get from a fast shutter speed. You'll need a decent lens to do this though, one of those multi-purpose 70-300mm 5.6AF lenses probably won't cut it.
or get a camera with a continual focus system that will keep a moving object constantly in focus. - drgkstep, on 10/12/2007, -9/+13dude, you don't have to be a genius to tell that is a flame projector for SHOW. dumping fuel that far behind the engines would not create flames like that. afterburners inject extra fuel into the exaust stream, after the engines compress air and fuel and ignite it, but still INSIDE the airplane. This produces an extened, brightened cone of thrust but not a cloud of burning butane like this, ALA fire breathing dinosaur monster trucks.
- HayString, on 10/12/2007, -1/+5thank you meridianknight and davidrools!
- crash999, on 10/12/2007, -0/+4Because it looks purty.
- vagarach, on 10/12/2007, -1/+5How many cool photos do you see in one day? You must admit that it's right up there, though.
- tuxidomasx, on 10/12/2007, -0/+4do a barrel roll!
- HabuMo, on 10/12/2007, -0/+3Here is a great AB shot
http://www.airliners.net/open.file/1164389/M/ - PsychoticCarp, on 10/12/2007, -0/+3What does the f-111 have to do with the war in Iraq? Its been mothballed by the US only the Australians have them now and they were built in the 60's
- jclassracer, on 10/12/2007, -2/+5i dunno. earlier today i saw this pic of a guy touching himself in front of a department store window. he was looking at mannequins without clothes on. the weird part is that the they weren't even complete mannequins, they were like armless and headless. he was just looking at their fake mannequin boobs. weird, right? i thought that was the coolest pic i saw all day.
- zackr, on 10/12/2007, -0/+3When you live practically next to the Avalon airshow you kind of treat this kind of thing with a 'meh' reaction. It was really getting old having planes refuelling over your back yard constantly...
- bmxboy661, on 10/12/2007, -0/+2i just thought it would be a really burnt baby.
but then i wondered why it would be the coolest picture i've seen all day? - Jabertsohn, on 10/12/2007, -0/+2Porn.
- AshTR, on 10/12/2007, -4/+6@archeologist
Don't you remember that story that says that Digg has users 12 and older? All the 12-14 years old got together and dugg that comment up. (Although I did too and I'm 16.) - antechinus, on 10/12/2007, -0/+2Don't knock the F111. These machines have a combat radius of around 2,000km. They afford the strategic ability for Australia to make 'deliveries' into Indonesia from the Australian mainland if necessary. That is the reason that they are still in use.
- justinmt7, on 10/12/2007, -0/+2Pilots have to be able to dump fuel. If a jet were to take off and something happens (like an emergency), it would have to turn around and land. A jet can't land heavy with all that fuel, so therefore one has to have a way to get rid of all that fuel weight--hence dumping. It's a common practice around the world. No one likes to waste the fuel like that, but people's lives are worth more than kilos of fuel.
- davidrools, on 10/12/2007, -0/+2JohntB and I were responding to crazychipmunk's question about the link that zaibatsu posted. we were actually replying to the comment rather than comment hijacking. hijacking an airplane comment...interesting...
But thanks for the info on a dump and burn. My question, does it serve any other purpose than to entertain airshow audiences? It seems to just be a waste of fuel that doesn't provide any thrust. - swicepick, on 10/12/2007, -0/+2I'm pretty sure the ability to dump fuel is a standard feature on military aircraft.
- pinkrubberband, on 10/12/2007, -0/+2Where did you find that picture? And what exactly is it? Totally made my day
- swicepick, on 10/12/2007, -1/+3@ nycmac247
Congratulations on putting the "dumbest comments I've seen all day" on the article of the "coolest picture I've seen all day." - inactive, on 10/12/2007, -0/+2wait, so theres a button in a F-111 to dump fuel and ignite it with the afterburners?
why? - piesforyou, on 10/12/2007, -0/+2@davidrools (#6398961)
from the wiki
"It has little practical use in combat except for potentially lighting up an area for observation at night, although naturally not during active combat (the plane would simply make itself into a target). It may also aid as a distraction for a heat seeking missile but is difficult to achieve as the heat is temporary, and can sometimes act as a smoke screen against a tailing enemy aircraft." - adrianwaj, on 10/12/2007, -2/+4The most amazing planes I think to look at are the new F-22 Raptor that went into Full production in 2005:

It's a SR-71 Blackbird of course.

- LowFuel, on 10/12/2007, -0/+1Bost, your photo is quite nice I think.
- taitacakes, on 10/12/2007, -0/+1I like how people are debating whether this is a flame thrower or really a dump and burn, but they do the dump and burn every single air show and at every major sports final or ceremony. It's okay, we're Australian, we see this all the time, we don't care about your physics.
